Which castle is better?
Level castle
It is considered the most reliable and burglar-resistant device. Invented back in the 19th century, it has enjoyed constant popularity among the population all over the world for several centuries. The lock mechanism is difficult to open due to a unique set of levers or plates (no more than 6) on which there are cut teeth different sizes. If the key is lost, it can be easily recoded without disassembling the case. The lever lock is vandal-resistant and continues to work normally even if small objects get into the keyhole. Modern locking devices are equipped with effective protection against burglary: false grooves, buffer mechanisms for recognizing master keys, armored plates, and therefore can only be opened by force.
Pros:
- durable and shock-resistant housing;
- high burglary resistance;
- ease of repair and replacement of the mechanism.
Cons:
- heavy weight
- marker key;
- the presence of a through keyhole that freezes in cold weather.
Important:
When choosing a lever lock, pay attention to the shank shank of the bolt. There should be a gap of 0.3-0.7 mm between it and the groove of the lever. A lower value will lead to frequent jamming of the deadbolt, greater force being applied when turning the key and its rapid wear, especially when closing and opening doors frequently. Too large a gap reduces the burglary resistance of the lock and increases the likelihood of opening the door using a special master key.
English (cylinder) lock
The cylinder lock design, equipped with a cylindrical coded or secret mechanism, is a universal option for entrance doors.

- compact dimensions;
- high reliability;
- small key;
- maintainability - the cylinder is replaced, not the entire lock;
- high secrecy (billions combination for expensive models).
Cons:
- poor protection against forceful hacking;
- the hole can be easily plugged with a match;
- costs of installing armor plates;
- The larva is unstable to concentrated acids.
Important:
Reliable protection of the apartment is provided by a cylinder lock with a hole cylinder, five or more “pins” - spring-loaded balls and pins that are combined with the key bits, a smooth drive and armor protection against knocking out the cylinder. Its reliability is significantly increased by multi-row keys with perforation at the end. It is almost impossible to open such a lock with master keys, only by bumping.
Disc lock
The device belongs to pin cylinder locks and differs high reliability. It does not use the selection of pins by height, but the alignment of discs at a certain angle. The key is a metal rod with a semicircular cross-section and transverse threads. In most cases, models are equipped with an automatic or semi-automatic (push-button) latch. They are more suitable for doors public buildings, the locking devices of which experience increased load.
Pros:
- does not freeze;
- high performance resource;
- opens when debris gets in.
Cons:
- the larva protrudes beyond the door leaf;
- automatic slamming function in the absence of a key;
- the cylinder is drilled out and knocked out.
Important:
A disc lock is often opened by drilling, so it is better to choose designs with carbide protective inserts.
Cross lock
A distinctive feature of the device is the cylinder and the key, which have a cross-shaped end. The mechanism consists of four rows of pins and has good secrecy - about 20,000 combinations, but it is not very reliable and can be easily drilled or opened using master keys.
Pros:
- efficiency;
- corrosion resistance;
- ease of use;
- If it breaks, just replace the cylinder.
Cons:
- low burglary resistance;
- low degree of secrecy;
- low quality;
- wears out quickly on all four sides.
Important:
Locks with a cross-shaped core are often made of unreliable material, due to which they quickly wear out and break. When purchasing it, it is better to choose models made of armored steel. In the attached documents it is designated as C85.

Whatever one may say, the choice of locks for the front door should be approached with special care and responsibility.
Pick up good castle decorating the front door yourself is not as easy as it seems at first glance. It is better to trust a qualified specialist in this matter, who, based on his knowledge and experience, will be able to advise you on the most reliable mechanism in terms of burglary resistance, which will serve you for a long and faithful service.
Sometimes it is practiced to sell doors with built-in locks, but, unfortunately, the degree of their reliability is often questionable, especially if they are Chinese, or simply do not meet all consumer requirements for providing protection.
As experience shows, it is most convenient, both for your pocket and for confidence in the reliability of the mechanism, to purchase locks for your front door from the same company where your door block was ordered. Moreover, it is not at all in their interests to offer you Chinese or other untested devices.
If this is not possible, look for separate locking devices, but mostly new models. Since opening and breaking techniques have not yet been developed for them, they will be more reliable. In addition to the obvious advantages, the acquisition of new models is fraught with significant financial costs, both during purchase and installation.
Door lock installation method
It is necessary to have a good understanding of the types of locks according to the installation method, so that the purchase and installation of a locking mechanism will be a success and not a mistake.
Thus, the types of locks for entrance doors are divided into padded, overhead and mortise mechanisms.
Let's look at each of them in more detail.
Simplicity of the hinged mechanism
Padlocks, it’s worth clarifying right away, are not used for wooden or metal entrance doors; they are intended for equipping gates and other similar structures. Simply put, where padlocks or mortise locks cannot be used.
Traditional hinged locks are durable, but not very reliable during operation. The closure of such a device occurs through a shackle, which is not difficult for attackers to crack or simply rip off if they have available tools.
If we talk about the material of the mechanism, then brass will make the job of robbers even easier, but cast iron will force them to put in more effort. The most resistant to physical hacking is a lock in a steel case.
Questionable aesthetics of the rim lock
The front door rim lock has more benefits than a hinged one, but still it is not installed on metal door leaves, rather than on wooden ones.
Installing an overhead locking device on a metal door inevitably leads to increased costs total cost designs.
In addition, such a lock can rarely be combined with the block door, due to the protruding part of the blade intended for attaching the seal.
And the aesthetics of the product are completely lost due to the installation of the mechanism on the inner visible side of the canvas.
Popularity of mortise devices
Mortise locks, undoubtedly, can be called the most popular and most often used to equip both metal and wooden doors. They are located inside the canvas, performing the function of protection and fastening. Unlike hinged ones, mortise mechanisms are not visible on the surface of the canvas, which looks very neat and aesthetically pleasing.
The mortise mechanism, in turn, differs in the type of mounting: insertion and mortise. Of course, installation is easier using the piercing method, because it is done in accordance with the lock, the locking plate of which will be visible at the end.
As for the insertion method, despite its complexity of installation, it is a guarantor of reliability and safety. The difficulty of installation lies in the need to locate the hatch on inner sheet doors.
Features of locking mechanisms
From technical characteristics The lock, and especially the operating principle, depends on the level of its resistance to unauthorized breaking. Locking mechanisms for wooden doors There are cylinder, level and crossbar.
Each of them has certain advantages and disadvantages, by comparing which you can choose the most reliable locks that best meet your requirements.
Cylinder mechanism: convenience and reliability
The principle of its operation is to line up small pins at the required positions when inserting a figured key into the well. If you try to open such a mechanism with a master key, as a result of missing at least one groove, the lock will immediately jam, which is quite problematic.
Locks with a cylinder mechanism are quite reliable, but still have one significant drawback, which is the weak point of the mechanism - the cylinder. Due to its design, it is quite easy to knock it out or drill it out. To avoid such situations and to smooth out the deficiency, special armored linings and balls are used to prevent direct access to the device.
When you try to drill, the drills will break from contact with the balls inside the mechanism, and the armored plates will prevent knocking out, as they strengthen the structure well.
In addition to this disadvantage, cylinder locks have a huge and undeniable advantage - ease of use and repair. If you lose the key or jam the well, you will not be forced to completely change the lock body, but only replace the cylinder, after which the mechanism will function correctly again.
The perfection of a lever lock
Like the cylinder, the lever mechanism can be found in almost every entrance door. The operating principle is based on plates (levers) located inside the lock. The interaction of the levers and their insertion into the corresponding grooves ensures the locking of the lock and the entrance door.
The degree of burglary resistance of a locking device is determined by the number of levers; to ensure complete security, the minimum number of plates must be at least six. It is impossible to get close to the keyhole; its narrow dimensions exclude the possibility of intelligent hacking.
As for physical hacking, there will also be a problem for attackers, since the lever mechanism is one of the possessors of a high degree of anti-vandalism.
To summarize the above, front door with a lever lock, can rightfully be considered reliable, especially when installing the device indoors. Do not doubt, the reliability and protective properties of the lever mechanism are excellent not only when equipped on a metal door, but also on a wooden one.
Questionable reliability of the deadbolt lock
If you are the owner of a high-quality steel door, it is not recommended to use the deadbolt mechanism as the dominant locking device, other than as an additional lock on the front door.
This advice is explained by the low level of security of the device, which can be easily opened with a master key, and the level of secrecy leaves much to be desired. The deadbolt lock is unlocked with a rather heavy key, which is not convenient to use and can be easily copied.
Required number of locks
How many locking devices do you need on one door to be sure of the safety of your home? Two is just right. The traditional, and perhaps the most competent combination of locks is cylinder + lever.
What can be gained by resorting to such a scheme? Firstly, than a large number combinations the key of the cylinder lock will have, the more difficult it will be to break into the mechanism using a selection of keys and a master key. Secondly, the lever mechanism is massive and durable, which means that it is not as easy to open it with a primitive tool as it might seem at first glance.
Additional measures to protect against hacking
To ensure that an intruder who does not enter the apartment through the door cannot easily leave it by opening the lock from the inside, the door leaf is equipped with a special lock pocket. It blocks the path to the secret mechanism and fastening the lock from inside the room.
By installing the armor plate under the covering sheet of the canvas, next to the lever mechanism, opening it will be difficult to achieve. And installing an armored cup helps prevent the cylinder from being knocked out or drilled out. Its price is quite reasonable, and it would be extremely unreasonable to refuse to install it.
There are some established rules, following which will not only allow you to acquire reliable protection property, but also to ensure a long service life of the locking product:
- buy products exclusively in specialized stores to get competent advice;
- do not purchase locks below resistance class III, which require about 10 minutes to open;
- choose devices with a minimum number of combinations of 100,000;
- When purchasing, pay attention to the appearance of the device and its component keys. Chinese and other low-quality locks are made in a handicraft or semi-handicraft way.
You can tell whether a product is of high quality or not by using the brand name on the keys. industrial method. Then you can be sure that the keys are highly clean and complex shape working part.
