How to choose a device and core

For the secrecy of the lock corresponds to the mechanism called the core, secret or larva. Its main purpose is to ensure the safety of the dwelling from possible unauthorized autopsy and penetration into the premises of the uninterested guests. In the larvae inserted the keys that, when turning, open and close the locks.

The larvae can be the most different.

The most common of them:

• Cylinder. Different degree of protection against unauthorized autopsy.

Such locking mechanisms are manufactured under the RIM standard, in limited quantities, or the Eurostandard DIN, whose larvae from different manufacturers are practically interchangeable. Cores are selected depending on the thickness of the web and the location of the fastening element relative to the inner and outer planes.

The table presents types and features of cylinders:

• Disk. Their difference from other mechanisms is the presence of rotating discs instead of the pins, which, when opening the locking device, are built under a certain angle. The key shape is a semicircular section, with propyl placed on it, according to the position of the disks.

The replacement of the larvae is harder, their nodes are not so universal, as in the mechanisms of other types. In this case, it is more expedient to replace completely.

With disk larva

• Cross-shaped. This is not a particularly reliable option. Inside the pins, sometimes you can even be tested by a conventional screwdriver. To get to the larva, you will need to fully disassemble the castle.

In constructions, pins are used, built inside the larva in four faces when turning the key. With a multiple secrecy options, cruciform cylinders in the lock can be easily opened using a screwdriver.

Tip: Do not change the larvae on such mechanisms, should replace the element completely. But in any case it will take full disassembly.

• Pin or English.

Such a door larva can be:

1. english. This is not too reliable design;
2. perforated, revealed only when knocking or driving a cylinder, which is quite difficult and long.

• Increased complexity. They are very difficult to hack, manufacturers make structures reliable and durable. The price of their more ordinary, and do not change the mechanisms with their own hands.

By purchasing high quality products of famous brands, you can not change the larvae for a long time. This most often occurs at the wrench.

Element of increased reliability ABLOY PROTEC

In the most complex shut-off mechanisms apply:

1. titanium case;
2. armored car;
3. a large number of combinations;
4. pins are made of refractory metal;
5. there are floating elements on the key.

It is impossible to choose the key to this lock, but the larvae is replaced quite real.

Secrecy of the larvae

For entrance doors, locks can be:

• Overhead.

Overhead

• Currency, more reliable closing on both sides to the key.

• Upper.

• Nizhnyhaving only locking feature and additional fixation on the latch.

With extra latch

Material for the manufacture of the mechanism and the number of combinations of the secret determines their properties:

• Reliability and probability of resistance to mechanical exposure.
• Resistance to wear.
• The probability of inclusion of keys.

Larvae can have three levels of secrecy:

• Low, with a number of combinations from 100 to 10,000. Made from low strength materials and a simple key profile.
• Average, with a number of combinations ranging from 5,000 to 50,000. It has a complex opening mechanism, but does not differ in very high performance.
• Higher, the number of secrets exceeds 100,000. They are distinguished by the quality of materials used for manufacture and high assembly accuracy.

Each larva has only its inherent design features that determine the process and the possibility of its replacement.

Choosing a new secret

The safety of the property and the life of the structure depends on the quality of the secret assembly of the lock.

When installing a product from a well-known manufacturer, it will not be difficult to choose the desired node.

To do this, you will need:

• Check the compliance of the new mechanism with dimensions and connecting sizes.
• Pay attention to the quality of the material from which the larva is made.

Tip: You should not purchase a product from silumin. This is a very fragile and short-lived material.

• For the secret, brass, steel, aluminum or alloy with zinc are best suited.
• The economy is not always justified. A cheap mechanism can quickly break, which will spoil the mood and will result in additional spending. It is known that the miser pays twice.

Causes of replacement of the larvae

It is clear that there is nothing eternal. Gradually wear mechanisms and rotating parts of it. This process can occur smoothly, and sometimes a normally working lock suddenly began to open the doors tightly. There are several objective reasons that lead to replace the secrets.

It can be:

• The breakdown of the node associated with the wear of parts during operation.

• Defects from the wrong attempt to disassemble the mechanism.

• Due to the mechanical shock on the doorway.
• After opening the castle with prudent tools when the key was forgotten (see).

• With hacking outsiders.
• When losing the key.

Disassembly and replacement of the secret

Before pulling out the larva from the door lock, if it has become bad to work, you first need to try to lubricate internal nodes, including the secret. In this case, WD-40 liquid or ordinary machine oil is used. If after that the lock works as bad, the larva will have to remove and disassemble, as in the photo.

To remove and open the door larch, you will need: cross screwdriver and roulette.

If a mortise lock is inserted into the door, the instruction of the work offers:

• Remove the middle screw of the mechanism.
• Paste the key into the well.
• Turn the key so that the larva is freely pulled out.
• Save the screw.

Overhead on door locks are removed completely. For this:

• The fasteners are out, which hold the lock on the door canvase.
• Two screws fastening the larch in their place are unscrewed.
• Screws are packed carefully to the side.

In more detail, the entire process of removal and disassembling the larva shows the video in this article.

Installing a new larvae

Before changing the larva in the door lock, it is necessary to purchase it correctly.

For this:

• The overall thickness of the door canvase with the upholstery or insulation is measured, if available.
• In the absence of changes, it is possible to focus on the dimensions of the dismantled cylinder, which is much easier.
• The diameter of the removed larvae is measured.

Tip: When buying a secret for the existing lock, take a revealed cylinder with you. If it is impossible, you need to focus on accurate measurements.

• The new mechanism is selected according to the color of the door, otherwise it will not look too aesthetic.

To install the cylinder you need:

• Purchased larva set in place former.
• Secure the screw, clearly hitting the hole, which is intended for fasteners.
• A minor stitching of the core in the lock plane will help to push it on the mounting element.
• The key is fixed in the closed position.
• The lock is checked for performance with the open, and then a closed door.
• The lock must open and close smoothly and silently.

Only a high-quality larva for the door lock will provide reliable protection against hacking and penetration of unauthorized persons.

One of the most popular, in demand, reliable and constantly developing systems of shut-off mechanisms is cylinder. She was born a little over one hundred years ago.

This system is convenient to operate, does not require applying super passions when opening the lock, and in the case of a loss, the key is enough to replace only (the larch), without touching the entire locking mechanism. Another undoubted advantage of cylinder locks is that all cylinders are combined with castles of different manufacturers. If you need to replace the larva, which will meet all quality standards, it should be understood which cylinder is better. It is about how to choose a really best cylinder, we will talk in this article.

What kind of cunning "beast" cylinder?

First, let's try to figure out what is a cylinder. This is a special device, with which the beggars are opened - the force of the key being coated in the keyhole is transferred to the internal mechanism, which ensures the movement of the shut-off reinforcement. In addition, it is in the cylinder all the secrecy of the castle is hidden.

The incredible accuracy and feature of the structure of the cylinder allows for the opening of the lock only the "native" key supplied with the product (most often "native" keys happens from three to five).

Cylinders are produced in the two most popular shades, harmonizing with locks and doors of any color:

• nickel-plated;
• brass.

Depending on the type of lockable mechanism, the cylinders are two systems:

• key key (to close or open the door outside and from the inside the key);
• clean key (Outside the lock opens and is closed with a key, and from the inside - a swivel handle).

Trying to understand what kind of cylinder is better, it should be aware of what would be reliable to be a mechanism, it needs additional protection provided.

How to buy perfect cylinder

There are many types of cylinders distributed over the level of secrecy and reliability, resistance to power influence. The main parameters for which first need to pay attention to:

• ease of operation;
• durability and wear resistance;
• reliability.

The fact that the wear is wear-resistant, directly depends on the quality of the performance of the internal components of the product, as well as the materials from which they are made. Be sure to consider the lubricant used in the device.

If you add here the quality of assembly of nodes and the entire device as a whole, we can talk about the reliability of the mechanism. The higher the indicators of the reliability and wear resistance of the cylinder, the lower the likelihood that at some point it can refuse to function or will be opened with a launder.

There is no reception against scrap?

The reliability of the cylinder depends on how effectively it can resist the power options for hacking:

• drill;
• knocking;
• overwhelming;
• tightening, etc.

Today there are many developments that contribute to withstanding any of the above options. First of all, they relate to raw materials from which they are manufactured - for example, it can be kalenny steel or other solid alloys undergoing hardening. Such materials practically do not take a single drill.

Separately, you can remember the Mauer cylinders (Mayer), made according to the special technology of the "red line", when when trying to break the mechanism, only the front part of it is chosen, and the cylinder itself remains inaccessible to hackers, but continues to function safely when using the native key.

Almost all models of the brand cylinders Mottura (MOTETTURE) in turn are equipped with a special system of protection against knocking out, and therefore they effectively oppose any method of force exposure other than drilling.

Most cylinder manufacturers offer consumers to acquire additional, which will significantly increase the security of the mechanism and, accordingly, the safety of the room.

Therefore, determining which cylinder is better, do not forget about the overlays distributing depending on the installation option for two types:

• mortise;
• overhead.

The first type of lining is mounted on the lock. Some of the most reliable are the products of the company ,. These models actually unreal to tear off the door web, and therefore their protective properties are incredibly high.

Patch protection is mounted on the external door canvas. Although, often they are more considered decorative, because it provides protection against drilling only until it is forced. Products of companies Kale (Kale), Ritko (Ritko) and others enjoy the greatest popularity.

Intellectual protection of cylinders

One of the options for opening the cylinders is the intellectual method, the essence of which is the selection of keys and beams. Modern models of cylinders are quite effectively opposed to this method, but not all. For example, cheap devices are quite quickly wear out, with the result that they are easy to open with any key.

In general, hack resistance of cylinders is distributed into several classes and depends on the time that the attacker will spend the discovery. The simplest, weakly crochet cylinders are opening in two or three minutes. At the opening of expensive complex mechanisms, the hacker must not be half an hour. However, so much time in most cases, the robbers are simply not. Therefore, if you really want to understand what kind of cylinder is better, ask the seller with the accompanying product documentation. It must necessarily indicate the class of hacking mechanism.

To avoid the opening of the cylinder with a launder, manufacturers equip the inner secret part with false grooves, in which the latter falls. Small wells are quite common, in which it is extremely difficult to insert a wash.

Reliable cylinders should effectively resist and so-called automatic lays operating on the principle of vibration leading to the opening of locking elements. In theory, you can even open in this way the most expensive and reliable model of the cylinder, however, as practice shows, in fact it only acts on inexpensive models, and it is not always.

One of the most common ways to open the locks is the "bumping" when a pre-prepared key model is inserted into the keyhole, according to which the hammer is broken or another heavy tool. As a result of such a blow, pin and pins are diverged, and it is easily rotated. Modern expensive models of locking mechanisms are easily opposed to such a method of hacking due to several factors:

1. A small locking well, which is difficult to choose the workpiece.
2. Durable internal elements and nodes capable of withstanding an increased power load provided during impact.

There are many models designed with such a calculation so that they can withstand the "bumping", but in general, the cylinders of many firms are withstanding this method of hacking. For example, these are products of the following manufacturers:

• EVVA;
• MUL-T-LOCK;
• Cisa and others.

Above the most popular methods of hacking, but there are other. In practice, they are actually not used, since they have long become ineffective. Such methods include the use of acid, which, according to some, corps the internal filling of the mechanism. However, on the metal used in the locks, a hydrochlorian raid is formed under the influence of acid, which does not allow acid further negative effect. In addition, the internal details of cylinders and locks are most often made from Kalena Steel or Melchior, which are actually not afraid of the influence of acid.

Big secret

Trying to determine which cylinder is better, be sure to check if its secrecy. This concept is often used to voice the amount of possible combinations of the cylinder generated by its pins. According to manufacturers, the most reliable models cannot have less than thousands of combinations, and in elite, expensive cylinders, the number of combinations reaches several million.

In fact, everything is much more complicated and a lot of characteristics should be investing in the concept of secrecy, among which:

• wear resistance;
• resistance to power influence;
• resistance to intellectual effects;
• the number of combinations of the cylinder;
• the probability of opening the castle similar "native" keys, etc.

In addition to the above characteristics, the quality of its manufacturer has a direct impact on the secrecy of the cylinder, which has a positive effect on its durability and reliability.

What are the cylinders for the people?

The easiest way to determine which is better to look at its cost. So, the cheapest models in a matter of minutes will easily open even a schoolboy, reading or looking at the Internet the appropriate literature or video clips. Quite often, the most cheap cylinders are implemented even without packing with the manufacturer. Such products not only can not increase the protective properties of the door, but also very quickly emerging, which leads to the need to buy a new product and, accordingly, additional cash spending.

Buying a cheap cylinder is justified only if it is purchased as a temporary constipation. For example, when carrying out repair work in the newly acquired apartment, which in the future suggest the acquisition of a new door with a full, reliable lock.

For the entrance door to the apartment or the house it is recommended to acquire cylinders of the average price category. Models from this group of goods significantly exceeds cheap products for reliability and ability to withstand various options for hacking. Even an experienced specialist will have to spend a lot of time to open the lock, the method of drilling or knocking, making a lot of noise, which will attract neighbors or just passing by people. Yes, and that, similar options for opening are not always effective, because it is used to produce cylinders, which prevents the layer of the product. Considering the use of modern reliable materials, the cylinders of the average price category are working trouble-free over the years, do not break and do not require replacement. Models of this price category are set at least 70% of doors.

The third category of cylinders, most expensive, guarantees the maximum level of protection and safety. Open them forces only to the genius of hacking, which all over the world is not so much. The cylinders of this type are able to withstand the power and intelligent hacking method. Especially durable materials, innovative developments used in the production of locks of this species, may even finally block the device at the slightest hack attempt, be it drill or selection of baking places. Naturally, the cost of such cylinders used in conjunction with specially designed, incredibly high. It is recommended to install them only if you are confident in the overall reliability of the door, which can not be broken, nor cut off the loops. Otherwise, spending on expensive cylinders are not entirely justified and better limit to the shut-off mechanism of the average price category.

We hope now you can understand which cylinder is better and acquired a really reliable and durable mechanism. When buying a product mandatory, consider all the above parameters and characteristics of cylinders. Do not guide only the seller's promises and the fame of the trademark producing mechanisms.

The lock - This is a portion of the cylinder lock that moves the goals, and on which the secrecy of the castle depends. Professionals are called a cylinder mechanism of secrecy (CMS). Our clients often ask the question: "How can I change the larva, and what should I know for this?" In this material, we will look at the main parameters of the CMD and consider some examples.

To properly install the cylinder, you need to know the following parameters: the length of the entire cylinder, and the distance from the edges of the cylinder to the center of the mounting screw. On the diagram is distances "BUT" and "IN".

The cylinder, which, both parts equal in length, is called equilateral.

If the length of the 2 parts are different, then such a cylinder is called versatile.

Its length is 90 mm. This size of the versatile larvae is often found in the doors of the Italian company Union, as well as in the door of the Chinese production outpost, master-lock, etc.
Parts of the cylinder are separated, the so-called swivel cam. Its width - 10 mm. The bias of the cylinder is measured from the center of the swivel cam. If the cylinder is selected in length correctly, it should not act much for the door of the door, decorative lining or door fittings. If the cylinder lock is configured, the length of the protruding part of the cylinder will depend on the type of damage installed, the installation method and the specific door. There are no special requirements for the length of the inner part of the cylinder.

The castle larva is the code part of the cylinder lock, which ensures secrecy and moves the deposit. It is due to the fact that the larva is inserted into the case and has an elongated oblong shape, it is called in the prostodoro "Licken". Single steel embryo.

In fact, the larvae of the door lock in a professional environment is called a cylinder mechanism of secrecy. Abbreviated "CMS".

It is the correct name of this important castle detail that we will use further in the text. But still leave the "larva" in some places for better indexation;)

You can buy a larvae or cylinder mechanism for the lock you can in the lock lock. And get a preliminary consultation - by phone mentioned above.

Frequently often from the buyer, we hear the phrase: "How can I replace the larva and what you need to know to pick it up"? The request has long been surprising for a long time: to figure out the entire variety of cylinder mechanisms of secrecy, their views, lengths and standards in an unprepared person is very hard. In this article, consider the important parameters of the CMD and find out some nuances.

TsMS species are a lot. Let's start with the most common, which correspond to the European standard DIN (Europrofile) and which are used everywhere.

This is what is primarily associated with the buyer with the "larch of the door lock":

EUROPROFILE Standard Mechanisms produce many countries: from China to Europe. The cost of the cylinder, depending on the model and the manufacturer, may vary: from 150 rubles to 20,000 thousand rubles. The higher the quality and the most famous mechanism brand, the more protective elements and innovative ideas embodied in the larch of the castle, the higher its value. For each model of a particular cylinder, you can write a separate material, for example, as an overview of the Slovenian CSM TITAN K56.

Here we will not stop on some particular product, consider only the main parameters when choosing a cylinder.

Length and displacement of the castle larva

We are confident that you do not need to explain the calculations of the total length of the cylinder - this is the distance from one edge to another. The desired cylinder length is selected taking into account the thickness of the door of the door and on the basis of which cylinder lock you have chosen.

As we see, two parts of the cylinder shares the swivel cam. The width of the swivel cam is always 10 mm.

The cylinder displacement is measured from the middle of the mounting screw hole in both sides: outdoor and internal.

The equilateral cylinder is the one in which both parts are equal in length. A versatile cylinder has different lengths of the same parts.

For example, below the versatile cylinder mechanism of the English type of Turkish production of Kale Kilit total length of 71 mm. Frequently used on plastic doors.

The second example: a versatile cylinder mechanism of Chinese production with a total length of 90 mm. It is this size of the castle larvae now is popular for Chinese doors.

The cylinder is correctly selected length should not be strongly played for the plane of the door of the door. If it is a wooden door, here the cylinder must be installed with a decorative lining or with a bar from the handle (permissible to look up to 3 mm). If the terminal layer is installed on the cylinder lock, the length of the outer part of the cylinder will depend on the specific armored layout, from the method of its installation and on the specific door.

There are no fundamental requirements for the length of the inside of the cylinder. But if from the inside, the mechanism will also be flush with the door finish or decorative lining, it will look like it will look aesthetic and harmoniously.

Larva castle with turntable

For the convenience of operating the larva, the door lock may have a rotary turntable. It allows you to close and open a cylinder lock from the inside without a key. At the same time, the "dead points" does not have a turntable - at any position, the lock key will always open.

The equilateral Chinese cylinder mechanism is 60 mm of length, with a rotary turntable from the inside:

The versatile Italian mechanism is 72 mm long, with a rotary handle from the inside (the increased inner part of the cylinder is calculated on the thickness of the inner panel of the door):

Other Standards of the Secrecy Cylinder Mechanism

If the cylinder described above is suitable for some standards, and can be installed in any cylinder lock case, then the following segreency mechanisms have other dimensions and are approaching strictly individually under one specific lock (or for some models of one manufacturer). For example, the cross cylinder mechanism of the Turkish company "Kale Kilit".

Suitable only under the locks of this type (it is possible to install in the locks of other Turkish manufacturers (for example, Fayn), or with a small alteration, under the castles of Chinese production (for example, 3m)).

But the domestic mechanism of secrecy under the Crimping Key:

Suitable only under the castles of Kirov production. And as you already, probably understood, the Kirov mechanism will not be able to insert into the Kale Kilit body and vice versa.

To some domestic overhead castles there is an opportunity to purchase a cylinder separately. For example, often broken mechanism "Fort", which is only suitable for castles produced in the city of Petrozavodsk.

The locks of terrible quality, the mechanism of secrecy and the lock assemblies are made for the most part of the silumin (a very fragile alloy), from here frequent breakdowns and, of course, the availability of the opportunity to purchase a new cylinder! In the next photo from left to right, you can see the cylinder mechanisms to the overhead locks "glazes" and "Iset".

Their problem is the same - soft materials and poor quality of manufacture. Often such specific cylinders (the possibility of choosing a cylinder of a better quality is not ordered and manufactured in China.

The lock cylinder is the code part of the mechanism that ensures the secrecy of the design and moves the deposit. Because the cylinder is inserted inside the case and looks an oblong detail, in the commoner it was painted with "larva".

Many buyers are wondering how to choose a cylinder for a lock, which must be taken into account and, in general, which there are varieties of this mechanism. Let's try to understand the entire structural diversity of "Lar", considering the basic standards, parameters and nuances.

Before choosing a cylinder, you should know that the types of "larvae" are very much. Denote the most common models that meet European DIN standards ("Euro-concrete"). In addition, their ubiquitous use has displaced other similar types of cylinders.

Certified mechanisms produce many countries: from Japan to Portugal. The price of "larvae" directly depends on the structural features and the manufacturer (from 100 to 30,000 rubles). The more serious brand and a better mechanism, the higher its cost. You can also add any innovative ideas, original material, etc.

In order for a simple man in order to figure out how to choose a cylinder, you must specify the main parameters responsible for the operation of the mechanism.

Length and offset

The first parameter is the length: the distance from one edge of the cylinder to the other. Depending on the thickness of the door leaf and the lock, dimensions vary.

The following is the offset of the "larvae". As a rule, the cylinder for is separated by a swivel cam, which is shifted in one direction, separating the mechanism on the outer and inner part. If the cam is exactly in the middle, the cylinder is considered equilateral.

Dimensions

For example, the sizes of cylinders for the castles of Turkish production of English type are as follows: 71 mm with a displacement of 40 and 31 mm, respectively. This design is used mainly in plastic products: office and verandas, arbors, and so on.

The most common sizes of cylinders for locks have Chinese mechanisms with a total length of 90 mm. This size is used everywhere in the input and interior doors of Chinese production, which literally flooded our market.

Choosing a castle under the cylinder, it is important to take into account that the entire design does not perform for the plane of the door cloth both from one and on the other side. If the door is made of wood, then the "larva" must be flush with a decorative lining. Maximum permissible peeping "larvae" - 3 mm: everything that goes beyond these frames can easily be used by crackers. In the event that the castle is equipped with a bron alphabet, the length of the external part of the mechanism will already depend on the specific sizes of this lining and the door itself.

Cylinder for a castle with a turntable

Sometimes the cylinder can be equipped with a rotary turntable for convenience. It allows you to easily open and close the mechanism without a key. It is worth noting that the turntable does not have "dead" points, so at any position the runner, the native key on the other side will always open the lock.

The main lineup is presented in our market by Chinese manufacturers (60 mm mechanism) and more expensive Italian models with a rotary handle (72 mm).

Other standards of cylinder mechanisms

If the above-mentioned models are suitable for almost any lock and can safely buy on standard doors, then the following mechanisms have specific dimensions and can only be suitable for a particular design or one manufacturer. Therefore, always pay attention to the "larvae" specification before choosing a cylinder.

The most vivid example of originality is the products of the Turkish company Kale Kilit. Their locks are distinguished by increased reliability, but are suitable only under the mechanisms of the same type. Some competent craftsmen can redo the Chinese castle under the cylinder from Kale Kilit, having obtained a significantly reduced cost of the mechanism.

Domestic castles

Domestic manufacturers are not lagging behind imported, although prices with similar quality of other times higher than Turkish. Kirov cylinders with a crusade have perfectly proven themselves, and just as in the previous case, the domestic mechanism will not be able to insert into the imported case and vice versa.

Before choosing a cylinder, it should be noted that some domestic mechanisms can be purchased by "larch" separately. A bright example is a frequent broken mechanism "Fort", which is produced in Petrozavodsk. The explicit cheapness of the design has its indisputable minuses: the mechanisms of secrecy together with the main cylinder assemblies are made of a challenge and fragile silumin alloy, hence the frequency of breakage, and at the same time the ability to buy a new cylinder assembly (good

Other domestic mechanisms like "glazing" and "Iset" suffer similar problems: too fragile materials together with low quality products. But, unlike Kirov castles, specific cylinders are not sold separately by plants, so you have to order them in China.

Secret

The cylinder in most cases is the weakest link of the locking mechanism. The attackers are melted, drill or just pick up the launder, so the reliable secret of the castle is the main obstacle for this kind of exconse. You need to choose a mechanism and save on the cylinder in no way. Consider the basic methods of hacking and how to avoid them.

Selection of laundry. The sensible manufacturer always equips its mechanisms with false grooves, significantly complicating the key selection process.

Bumbing. The method is based on rough strength: any suitable key in the well is inserted, then it is hung with a hammer. Pins and pins diverge, and the mechanism is already useless. In this case, high-strength cylinder material and non-standard well helps.

Drilling. The only protection against this kind of hacking is reinforced alloys and metals that are not drilling.

Knocking out The main protection is again the materials from which the cylinder is made. The optimal option is the tirdo-allies that do not get bend, do not crumble and reliably protect against this type of hacking.

Summarizing

Choosing a cylinder for a lock, in no case should not save. Nice materials are not seeing, so the caming Chinese design for 300-500 rubles will not save you even from the amateur fraudster. It is also worth considering such factors such as the durability of the mechanism, design and ease of operation. If your family has children who you trust the key, then the castle should not be an obstacle to get home. Be sure to take into account this moment. Sometimes, in pursuit of anti-burglar mechanisms, people forget about such obvious things as easy to use, and suffer with uncomfortable keys and cunning castles. Therefore, this factor also needs to be taken into account.
