The bottom pins move within pin channels inside the cylinder assembly and are cut at different lengths corresponding to the lock keying. The driver pins are installed in the lock housing and spring pressure forces them to penetrate the lock cylinder and prevent it from turning.
The mechanism involves the movement of lower pins within channels inside the cylinder assembly, which are trimmed to match the lock's specific keying requirements. Driver pins are then inserted into the lock housing, where they are forced by spring pressure to penetrate the lock cylinder and prevent rotation.
