When it comes to mortise locks, several common issues can affect their function and security. Some problems include loose or sticking latches and bolts, making it hard to secure your door. You might also find keys that turn but do not retract the bolt, leaving your door open to risks. Misaligned strikes or door frames can cause big problems, as can jammed lock cylinders and keyways that stop smooth operation. Other issues include worn internal springs or cams, which can lead to locks that do not work well. Damaged thumb turn or lever handles may also need to be replaced. For those with smart or electronic mortise locks, losing connectivity can be very frustrating. Our skilled locksmiths can diagnose and fix these problems on-site. They use high-quality tools and replacement parts to make sure your locks work perfectly.
We start by inspecting the door hardware to find the cause of the problem. This could be due to wear, misalignment, or electronic failure.
We replace broken springs, pins, or latch assemblies with original parts. This ensures long-lasting durability.
We realign strike plates and adjust the latch to make sure the door closes properly and the key turns easily.
After the repair, we test each mortise lock. We check for smooth key function, lever tension, and ADA-compliant operation.
If your door hardware is severely damaged or outdated, see Commercial Lock Repair – Greenbelt, MD for full-door restoration options.
Repair is often the best choice when the internal parts are still working but worn out. However, replacing the item may be better for old hardware or if it keeps breaking.
