The lock cylinder is a part of the car door locking mechanism construction. This part is the primary functional element of the lock.

Types of lock cylinders

  • wafer tumbler (the casing houses wafers pressed by the key. When their position is coaxial, the cylinder rotates and unlocks the lock);
  • pin tumbler (a mechanism with locking and coding pins).

Construction of the lock cylinder

The pin-tumbler type construction includes the following components:

  • housing;
  • springs;
  • plug;
  • pins;
  • gasket;
  • tailpiece.

The key grooves act as wedges, lifting the pins in the lock cylinder.

Main functional elements of the wafer cylinders are spring-loaded wafers with grooves. When the correct key is inserted into the lock, the wafers rise up out of the groove, allowing the cylinder to rotate.

The lock cylinder operation tips

To extend the part service life, you should regularly use lubricants intended for car locks.

Professionals also advise using protective covers that prevent contamination of the cylinder.
