How to Open a Mechanical Lock?
Pin tumbler lock:without a key in the lock, the driver pins (blue) are pushed downwards, preventing the plug (yellow) from rotating. An additional pin called the master pin is present between the key and driver pins in locks that accept master keys to allow the plug to rotate at multiple pin elevations.
The pin tumbler lock uses a set of pins to prevent the lock from opening unless the correct key is inserted. The key has a series of grooves on either side of the key’s blade that limit the type of lock the key can slide into. As the key slides into the lock, the horizontal grooves on the blade align with the wards in the keyway allowing or denying entry to the cylinder. A series of pointed teeth and notches on the blade, called bittings, then allow pins to move up and down until they are in line with the shear line of the inner and outer cylinder, allowing the cylinder or cam to rotate freely and the lock to open.
So those of you who use this lock should take note which hides a huge security risk. If you lost the key, somebody else picked up can be copied at any time, at any time can give the thief bring “door” opportunity, even without the key, the thief can also use professional tools, easy to unlock the door.
