Lock Repair in Monroe County, MI

Lock repair covers fixing locks and door hardware that are worn, loose, sticking or broken instead of replacing them outright. That can include freeing up a stiff cylinder, replacing worn internal parts, adjusting a latch or strike that doesn't catch, tightening loose levers and knobs, or addressing hardware that keeps a door from closing properly. CS Lock and Key repairs locks for homes and businesses, including commercial storefront hardware. When a lock is beyond repair, we can install a replacement instead. We work on residential knobs, levers and deadbolts as well as storefront deadlatches and other commercial door hardware.

A lock that sticks or doesn't latch fully often gets left unlocked, and a door that doesn't close all the way is an open invitation. Small problems like a key that's hard to turn or a latch that needs a push tend to get worse until the lock fails completely, sometimes leaving you locked in or out. For businesses, a faulty entrance lock can mean an unsecured store overnight or a door customers struggle with. Repairing locks early keeps your property secure, extends the life of your hardware and usually costs less than waiting for a full failure.

For lock repair, describe the problem as clearly as you can, such as a key that's hard to turn, a latch that won't catch, a loose handle or a door that won't close, and send a photo of the lock if it's easy to do. Let us know whether it's a residential or commercial door and the brand of the lock if you know it. Keep the keys for the lock with you. We'll need to confirm you're authorized to have work done on the property. We'll diagnose the issue on site, repair what we can and let you know if a replacement makes more sense.
