PRINCIPLES AND FUNCTIONING OF THE MECHANICAL LOCKING SYSTEMS
In the mechanical locking systems movement of locking elements - ship or tongue is done by turning the mechanical key or a special handle for this purpose. Management of mechanical systems manually is optional, that is mechanical driving force is the human hand. Conditional systems consist of two parts - lock and latch mechanism.
CONCLUSIONS MECHANISM
Much of the mechanical systems locked unilaterally, but there are those locked bilateral, trilateral and four. In bilateral locking lock by lock or rough language on both sides of the door. This type of lock is desirable to fit if the knuckles of door are weak and there is a greater danger if they fall under someones influence or exterior door is open and potential thief could cut hinges and open the door from there. To this end, if you want to avoid double lock and stay with unilaterally, may put the so-called dormant rough on the knuckles.
The tripartite and four locks for extra security against bending the door when pressure in some of its edge
Essential to the strength and sustainability of a lock is the way her fabrication and material from which it was made. There are cases in which a poor material that very easily break or bend, and those in which the structure of the lock is designed so that they resist any attack. Unfortunately materials used are often hidden beneath the decorative coatings and its impossible for you to understand their quality. In these cases you can only trust in the name of the manufacturer and product quality, but only if you have one hundred percent sure that in your hands is not a forgery, a genuine product is guaranteed origin.
Note how come out of the rough lock in the locked position. This is necessary to ensure a good lock on the door, which is within at least 1 cm penetration in the box ensures that mechanical pressure on the door will be rough enough inside to resist. Some method to open the locked door is by stretching at the checkout, where lock is. In this case there are two options for protection. The first option is the depth of the rough is so big that as to bend box, you can not out beyond. This practice is very complicated and expensive. The second option is much cheaper and effective - you just have to fill the space between the cashier and carrying beam, so that it is impossible to bend the box so easily.
Almost all mechanical locks have been installed on the wing at the door. Those with many locks are placed still in the process of making the door as a consequence can not be installed. Only double locking spar type can be mounted later, but placed outside of the inside of the door and not a precise aesthetic. Unilateral conclusions can be fitted at any time. Whatever be the type of lock and as it is multilateral, always visible element of the lock. This is the least mechanical lock that is directly related to the locking mechanism. This allows the thieves even not to attack key locking mechanism, as can use visible parts of locking systems to support (benchmarks) points to determine which type of system, the weakest locations and its exact location for the attack. For example two centimeters above the lock, six millimeters to the left be pierced three milimiters with rechargeable drill hole (quiet and without cable) and the appropriate instrument is pushing the locking mechanism. Duration - precise, clean, quiet, fast, easy, cheap. This problem is solved with some of the electronic locking systems.
There are mechanical locking systems that unlock from the inside without a key – it is done for convenience and quick evacuation in an emergency. No matter how practical is this mechanism ,it has one major shortcoming, and it's that when you get into a subject in order theft through a window,exit and removal of property takes place through the door. This type of lock saves a lot effort and the need to seek spare key left hidden somewhere in the facility. This problem is solved with some of the electronic locking systems.
When vandalism to the mechanical locking systems or to the door (bending, mechanical fractures or etc.) even lock is passed and the door is not open, it is possible to lock damaged (bent, broken) and can not be open then even with a key. The only option for opening the door is by mechanical means - cutting, drilling. If for some reason, in the process of exploitation, broke one element of the lock (and this happens often), the only option for opening the door is using cutting, drilling. Even to open lock for much of the mechanical systems are not available spare elements and will need to buy a new lock system.
LOCK
Security mechanical lock is determined by the secrecy of the lock and key. Much easier to dispose lock than locking mechanism. In this case, regardless of multilateralism lock mechanism and the thickness of the rough, if the break is (mechanically or unlock) the lock, with one rotation will unlock all the lock.
There are two main types of fasteners. The first type are the so-called cartridges, which are universal, code part in the cartridge and transmit it via thumb movement of locking mechanism. There are some other types of keys and security of its code. Due to the universality of the cartridge may change the type of key (rounds), which is used by replacing with a new one. The second type locks are so-called cash locks, in which code is part directly related to the locking mechanism. This type locks, to change the type of switch is necessary to change the entire lock. When the locks type cartridge security is determined by the accuracy of making keys. Because of mechanical windages which technology or appear during the operation, the number of combinations of keys is very limited. Often occurs any key "surprising" to unlock foreign lock. 
METHODS DECOMPOSITION OF THE LOCK:
There are so-called picklocks representing devices that within seconds, minutes at most is the code of the cartridge. This method is quick and quiet, but requires skill, traceless. It may come into the facility and leaving again to conclude the lock.
Another method for quickly dismantle so-called sword pad. This is a device thatis breaking the coded locking-fingers cartridge and it remains without a code. This is a quick and quiet method does not require skills, sometimes leaving traces. It may come into the facility and leaving again to conclude lock.
Another method is the breaking of the cartridge. If there is a place for holding a cartridge using design weakness in the middle of the cartridge, through special keys grip is outside of the broken shooter, and then smoothly can be opened. The method is very fast, relatively quiet, requires no skills leave quite visible.
Next method is through drilling a code of the cartridge. Comparatively slower than those in noisy and leaves visible.
The cartridge type of lock is extremely unstable in vandalism. By put on a stick or another object or injection of glue into the lock can very quickly, cheaply and unbeknown to destroy a locking system and to force its owner to break itself, which would create a lot of his headaches, take time and considerable financial means.
If your key is stolenor you lose it you will need to change the cartridge and remove new keys for all users to to prevent unlocking this lock. This is a slow process, depriving significant financial resources.
The advantage of these systems is that it is possible to unite the so-called master system, with a special selection by mechanical codes is so that you have hierarchical key. This means that one key (master key) can open all the locks in the master system may have a key that opens only set of locks or a lock. This system is very convenient for hotels or companies, but deficiency is that it is expensive and if it is stolen or lost a key group will have to master the entire system shiftwork. But as the master systems are expensive and are applicable only within a company or building, in most cases each carry a huge connection with the keys to all doors, which have access. This problem is solved in electronic locking systems.
The disadvantage of any mechanical systems is that it is impossible to choose what and when to an unlocked door. Asit is not possible to follow when using certain key.
Keys to lock type cartridge is small, comfortable to wear and use.
The key may be copied without your knowledge if you take its mechanical footprint or just quickly taken out in duplicate locksmith. This occurs most often in internal sabotage from friends or acquaintances. Unfortunately, in no way to know who and how the key is your neck.
Mechanical switches Exports in continuous use due to mechanical friction, which was put in place the key and encoding and transmitting the mechanical movement of locking mechanism.
Paper type locks for locks is widespread views that are more secure locks on a cartridge. This applies only to cash the real quality locks. More recently, the market is very spread Paper type locks that are decently cheap, but as security is almost zero, as can be opened with hardly no jagged skrew-driver. Quality cash locks are very precise, which are required to dismantle very skills and precision instruments.
Quite widespread method of unlocking cash locks through a device called hedgehog, which selected combinations of cash key while unlock lock. The more imprecise is Great, the faster open. That goes for frequently used locks that as a result of mechanical wear and windages operating loss of accuracy and can be opened quickly.
Cash locks are not vandal stable. Injection of glue in the locks leading to the same problems as in type Patron - cutting, broaching, drilling.
If you lose or steal your key, you must change the entire lock and remove new keys for all users to not who has stolen or found the key to unlock this lock. This is a slow process, depriving significant financial resources.
The disadvantage of any mechanical systems is thet it is impossible to choose what and when to an unlocked door,and also to follow when using certain key.
Keys to type Case lock latches are big, heavy, ridged, very awkward to wear and use. If you have a few locks, link your keys is huge, heavy and annoying (especially during the warm months when no pockets). This problem is solved in electronic locking systems. The key may be copied without your knowledge if you take its mechanical footprint or just quickly taken out in duplicate locksmith. This occurs most often in internal sabotage from friends or acquaintances. Unfortunately, in no way to know who and how the key is your neck.
Mechanical switches Exports in continuous use due to mechanical friction, which was put in place the key and encoding and transmitting the mechanical movement of locking mechanism.
