Cylinder core simply explained

Cylinder core in an ABUS locking cylinder
The cylinder core is one of the most important components of a lock cylinder. Only when the cylinder core is turned by the correct profile key can the locking cam, and thus the bolt in the lock, be actuated.
In double-sided doors, the two cylinder cores are connected by a coupling. In the center of the cylinder housing is a recess for the locking cam, also called the follower. A follower hub is used to ensure the locking cam fits securely in the housing.
The cylinder core is the part of the lock cylinder that contains the keyway. In everyday language, this channel is also called the keyhole. The profile key is inserted into the keyway to lock or unlock the door. The profile key can only turn the cylinder core if its profile aligns the locking pins (tumblers) located in the housing and cylinder core correctly. If a key with the wrong profile is inserted, the tumblers will block the attempt to turn the cylinder.
If the cylinder core, and therefore the lock cylinder, is defective, the lock can no longer be locked or unlocked. In this case, it is necessary to contact a locksmith who can perform a professional door opening and expert cylinder replacement.
