The choice and installation of the castle on the entrance door is the usual case for the nurses or for those who decided to strengthen the entrance to their home. The case is usual, but the choice is not easy: a variety of diverse types and models of door locks offer domestic and foreign manufacturers. It is not worth a hurry in such a choice: ensuring housing security requires a thoughtful approach.
The lock for the entrance door ensures the reliability of the entire apartment, so it is not worth saving on it.
In addition, as you know, no money does not happen, so the search for the lock for the entrance door is usually associated with reluctance to overpay for him extra money.
Approach to the acquisition of the castle
Before choosing a lock on the door, you should decide on a number of very important issues:
- How many locks should have an entrance door;
- What models provide better protection against hacking;
- what is better to use, overhead or mortise versions;
- What types of locking devices from all the castle varieties are most suitable by the price / quality criterion.

Housing protection practices by installing constipation at the entrance door helped to form a general summary of the following recommendations for those who have not yet decided on protective events:
- It is better to put on the door of 2 locks than 1, but 3 is already an excess that leads to an increase in time to open and closing the door, which in itself can be unsafe and also weaken the door canvas.
- Put 1 good castle better than using 2 low-quality.
- A high-quality lock with the provided protective function can replace 2 good but not having to protect models.
- It is preferable to use on the door of 2 locks, but fundamentally different designs.
- When installing and installing locking devices to the input door, it should be remembered that the door also prevents unauthorized access to these devices as they - the opening of the door.
- It is better to spend big funds to protect the apartment, including the locks than spending money to restore the stolen property.
Thus, taking into account the presented recommendations, you can proceed to the process of selecting such a desired device to protect the house.
Locking mechanisms for the entrance door
Overhead and mortise locks
Scheme of the device of the overhead lock.
Devices that fix doors in a closed state and preventing them from the opening without the use of special devices (keys, cards, control panels), differ in the installation method and, accordingly, are divided into overhead and mortise species. The 1st belongs the locking mechanisms that are attached to the door and door frame with their parts. By 2nd - locks, the main mechanism of which is crashed into the canvas of the door, and the shut-off part - in the door frame.
Sometimes even such locking complexes, which have mobile parts, called the Bolt, can, put forward, block the door through the 3rd directions: up, down and horizontally.
Currently, overhead locks have lost their attractiveness for the reason that the method of fastening such devices is not mechanically reliable. If they are used, then in old houses or in a pair with the main locking mechanism.
Therefore, wishing to acquire the lock more often stop the selection on mortise models, which are presented in the modern market in a huge amount.
Existing mortise locking devices may differ in many design features, ranging from the metal used for the manufacture of the maintenance of the driving parts of these devices. To overcome the specified blockages by the method provided by the developer, it means to apply the key to the lock.

Types of blocking systems used in locking mechanisms
Connecting the electromagnetic lock.
According to constructive types and methods for blocking an unauthorized opening of the lock, the locking devices are divided into mechanisms in which the specified function is carried out: mechanical, mechanical electrical and mechanical electron methods.
The first type of devices uses in its design such a combination of the parts of the locking mechanism and the inserted key, which eliminates the manufacturer's free opening and closing the lock. In mechanoelectric systems, unlocking the locking mechanism is carried out by introducing a code combination of electrical pulses by pressing the corresponding buttons of the lock control panel. The blocking of mechanical electronic systems is removed by an electronic signal coming from the control magnetic card, through the reader and the controller, to the corresponding magnetic lock.
The choice of electrical and electronic locking devices for the home - the solution is quite rare, since their good functioning is associated with the constant availability of electricity. Not everyone can afford financial and resource costs conjugate.
Installation scheme of the Invisible Castle.
However, in recent times, the models of electromechanical locks appeared in the market, called invisible locks, began to be used in demand. The mechanism of such locking devices is triggered from the signal coming from the mobile control panel. The operation of such a mechanism is provided by an electrical drive that again requires the presence of backup electrical power sources in the stationary device. On the other hand, to equip keyaches for such models there is no need that is undoubted advantage. Potential attackers will not be easy to determine where the lock is located and how it can be opened.
Mechanical locking systems for locking devices do not require additional third-party resources. Such types of locks are quite simple in the installation and reliable in operation, so more in demand. Especially since the selection of such devices is very large. And the correct, competent implementation of this choice is possible on the basis of a thoughtful and detailed study of the issue.
Types of mechanical locks of locking devices
Castle models, the blocking part of which is purely mechanical, is produced much more than others. Objectively, this is quite explained: the period of the existence of mechanical locking devices is much greater than that of electrical and electronic models. During its existence, mechanical locks from simple devices that could be opened with a nail, turned into masterpieces of human thought. Currently, the locks used with mechanical blocking systems can be divided into several types:- rush;
- cylinder;
- disk;
- Suwald.
Rush locks, their use
Rush locks are very guided and not blocked in the absence of a key.
Rush locking devices are characteristic of what they are opened by simply input into the key lock with inclined special slots, without its additional turns. For each device, its number of slots is installed, their character and tilt. The entered key with its slots interacts with the elements of the mechanism (racks) in such a way that the bolt system is removed into the lock case, opening the door. The devices of this type are usually very heavy and deprived of the desired design. The keys to them have a greater length and the corresponding weight, which is extremely uncomfortable when mobile keystrokes. In the form and material of the keys, the choice is small: they are either round or flat, made of metal. When opening such locks, a large muscular effort may be required. Most often, such models put on the entrance doors of special buildings, such as garages or sheds. In the absence of a key, the mechanisms of such models are not blocked. Rigel can simply move away if you organize access to it.

Cylinder and disk locks
Cylinder lock diagram.
Cylinder locks were obtained from the form of a blocking element made in the form of a cylinder. This element carries the blocking code, which can be removed only with the key carrying the corresponding response combination. A structurally blocking cylinder consists of 2 parts inserted one to another. The outer part contains the elements of the blocking code, and the inner having the ability to rotate around its central axis is designed to introduce the key to the corresponding form containing the necessary code information to remove the lock lock.
When the receiving part of the cylinder comes into contact with the entered key, the lock is removed (if the key is suitable for the opened device). The transmitting mechanical moment on the cutting of the lock is carried out by a swivel cam, rigidly connected to the inner cylinder of the locking device. This cam moves the battle system in the desired direction: to open or closing the door.
The selection of such locks allows you to get locking devices of very high resistance to attempts to open them by possible attackers by selecting keys or using mobile keys.
If in the first models of the cylinder locks, the blocking code was gained using a different number of special pins installed on the springs, which, without being "recessed" to the neutral state inserted by the key, were blocked the possibility of moving the riglel, then modern systems are complicated. In them, blocking codes can be closed using mechanical and magnetic systems located in the cylinder instead of blocking pins. Moreover, the keys and lock magnet interact in contactless way. Choose a code combination and create an appropriate keyboard for such locks is simply impossible - it is easier to hack than to open. In the case of a key from such a castle in dishonest hands, nothing terrible will happen. Make a working copy from it will not work anyway.
Disc lock device diagram.
Castles disk principle of work are similar to cylinder locking devices: Also in the blocking cylinder, a code combination is created that prevents the free movement of the riglel. The difference of disk models is that the code combination is recruited using the installation of special disks with structurally specified grooves and slots. The more the number of such discs participates in the set of blocking code, the harder to open the lock without a complete key.
The scheme of the work of such models is not complex: the original key introduced into the well turns the discs of the locking set before receiving the general longitudinal groove on their edges, which corresponds to the size of the rod transmitting the opening force on the beel.
Installation scheme and operation of the early response lock.
The selection of modern cylinder or disk type models will allow you to install a lock with a blocking code of high complexity to the entrance door of the house or apartment. This, on the one hand, will not allow possible attackers to penetrate the building protected by the castle by disclosing the locking mechanism, and on the other hand, the reinforcement of such models may simply break in order not to spend time to endorse the blocking.
Devices of this species have a vulnerable place in its design: conjugation of the inner shut-off mechanism with a plug-in locking cylinder, which is carried out through a certain transmitting item. If you remove the lock knot, then the device can be fluently moved.
Manufacturers of locking devices take steps to strengthen a number of elements of such structures, however, the principle of construction does not change. At all, the Suwald models of locking devices look in this light.

Suwald castles
Diagram of the device of the Suwald Castle.
Suwald locks are named according to the name of the inner metal plates (Suwald), which are included in the locking system of the locking device. The more plates take part in ensuring the locking of the movement of the battle of the reiglee, the harder it is to open the lock without the original key.
The keys for such devices are a round metal rod (rod), a diameter of about 5 mm and a length of about 120-150 mm, at one end of which is a flat head of plastic, on the other - a flat metal part of a rather complex configuration. This flat part of the key, for good locks, it usually happens on both sides of the rod, has grooves, slots and protrusions that correspond to the set of the locking device. When you enter a regular key to the keyhole and its turn, the slots and the protrusions of the flat part come into interaction with the Suwalds of the lock, remove the blocking moment and transmit the rotation of the key to the battery.
Thus, by choosing in favor of the Suwald Castle model, it is possible to obtain a fairly strong, resistant to external physical exposure device, the secret of which, however, is not so reliable as the model of the cylinder blocking principle.
If the Suwald models are easier to open, but heavier to break than cylinders, then it is reasonable to combine the advantages of the first and second.
Types of keys for the Suwald Castle.
It turns out that the optimal choice is the installation on the front door of the house 2-locks: a cylinder and a suvalid model. However, it is not necessary to cut two of these individual devices to the door. Contemporary manufacturers can find models that combine in one housing 2 independently active locks with a cylinder and a suvalden mechanism. There are similar devices in which the cylinder lock unlocks Suwald, and the latter is already the door.
By choosing the necessary locking devices, it should be remembered that, in addition to the originally present characteristics, due to the type and type of locks, you should pay attention to their additional features.
For example, it is recommended to purchase mortise locks with the number of riglels of at least 4, made of high-strength steel, non-hacksaw for metal, and select the device in the safety class not lower than the 3rd.
At this point of choice, it is necessary to clarify, for which doors the model is intended for, since the mounting systems for metal and wooden doors have their own characteristics.
It will not be superfluous to obtain additional information about the materials applied in the product, data on the quality of manufacturing and service life. Practice shows that castles manufactured by European manufacturers are higher than the quality level than domestic or Chinese products.
In addition to the locking devices themselves, it is worth paying attention to their additional protection.
The modern market offers special armor plates for additional enhancement of the door web. If necessary, you can install a protective damper on the lock well, which opens and closes the well by a signal from the control of the mobile panel.
However, it should be noted that the castle mounted on the entrance door, whatever it be wonderful, will still not solve the question of the security of the house. Only a complex of protective measures, which includes a security alarm device and restricting access to unauthorized information about the availability of values in the apartment, as well as the debt of the host in it, you can protect yourself from intruders.
