Traditional locks work


The Pin-Tumbler lock is one of the most commonly used locks in residential properties. The locking mechanism in these locks has a series of spring pins that are in turn inserted into the cylinder. The cylinder consists of a set of pins that are designated as key pins and drive pins. When the correct key is inserted into the locking mechanism, the key pin is raised, which pushes the drive pin up.


Once the correct key is inserted into the lock, the drive pin and key pin are aligned at the cut line. Then the key can be rotated in the lock, unlocked, and sometimes locked. If the wrong key is used, the misalignment of the pin will prevent the key from being rotated because the pin will be tied at the cut line.


When a key is used to activate the locking mechanism, most traditional locks work, which will enable them to be locked or unlocked. Some very common examples of these traditional locks are pin locks, rim locks and mortise locks.
