What is the difference between a Euro and Rim cylinder?

Euro cylinders sit within mortice locks; Rim cylinders are surface-mounted and used with nightlatches.

Can I replace just the cylinder in a door lock?

Yes. Cylinder locks are modular—swap the core without changing the full lock case.

Can cylinder locks be keyed alike?

Absolutely. Many of our locks can be keyed alike or built into a master key system.
