Types of locks and keys

there are many types of locks and keys but the main types of locks and keys we will discuss in this article 

ENGLISH KEY

The key to the cylinder lock. One of the most common types of locks. Very low protective properties. Usually, lock cylinders with such keys are poorly protected from key selection or force breaking of the cylinder.         

DOUBLE-SIDED ENGLISH KEY

The key to the cylinder lock. Almost identical to the first key, but complicated by the use of the second side of the key. The security properties of a lock with such a key are only slightly higher than with an ordinary English key.    

CROSS KEY

The key to the cylinder lock. Also a very common type of locks with very low security properties. Despite the rather complex shape of the key, due to the insufficiently hard metals used in the locks, such locks can be broken with a simple screwdriver.      

FINNISH KEY

The key to the disk cylinder lock. Low protective properties. Practically not protected from power hacking and drilling.  

PERFORATED KEY

The key to the cylinder lock. Cheap Turkish and Chinese locks, with cylinders of this type, are quickly opened by thieves by simply breaking the larvae or bumping, using a specially made key or percussion gun. More expensive, modern locks, with bumping protection and armor plates protecting the lock cylinder from force, are a good protection for your property. 

LEVEL KEY

Another common name is “safe” – the key to the lock with a lever mechanism. A good lock of this class can make the most experienced burglar sweat. Like other locks, this one has its weaknesses – simple, cheap locks are quickly opened with a special thieves’ tool – a roll, or drilling.
