Complete Process for Replacing a Lock Cylinder

Professional lock cylinder replacement by master locksmith:

Verify identity, check door type, confirm lock core specifications and dimensions, and confirm the quote.
Remove the screws from the door lock panel, then detach both the interior and exterior handles.
Remove the old, damaged lock cylinder and clean dust and debris from inside the lock body.
Install a new lock cylinder compatible with the model and secure the screws.
Reassemble the handle and panel, then repeatedly test key locking, deadlocking, and safe functions.
Perform multiple open/close cycle tests to confirm smooth operation, then deliver all keys.

We do not recommend that homeowners without prior experience purchase and install a lock cylinder themselves. With so many different sizes and models available, ordering the wrong one can lead to installation failures—such as doors that won't close or keys that won't turn—and may even cause permanent damage to the lock.
