Ensure Proper Alignment: Verify that the rim cylinder is aligned correctly with the strike plate on the door frame. Adjust if needed to ensure smooth operation.

Dispose of the Old Lock: Properly dispose of the old rim cylinder and any packaging from the new lock. Keep the key in a safe place, and you’re all set with your newly installed rim cylinder lock.
