What goes wrong
We handle common residential failures: a jammed deadbolt that won't retract, a cylinder that turns but doesn't move the bolt, snapped keys stuck in the plug, and mortise locks with warped faceplates. We diagnose by inspecting the door, frame, and hardware to see whether the issue is the lock body, the cylinder, the strike, or the door geometry. For older multi-point and surface-mounted locks we check each actuator and the spindle so the repair addresses the broken part rather than just the symptom.

What the job involves
When a key breaks or the cylinder is scored we use pinning kits, extractor tools, and replacement cores or whole cylinders as needed. For rekey work we remove the cylinder, match the new pin stack to your remaining keys, and then test every cut to be sure the plug rotates cleanly. If a latch is misaligned we may replace the strike with a reinforced strike and adjust the door stop or the rebate so the bolt has full engagement into the jamb.

Good to know
For electronic or keypad locks we bring the common batteries, programming tools, and replacement mechanical parts where the actuator has failed. We can also convert electronic hardware back to a mechanical cylinder when requested. While we’re working we secure the immediate area, lay down a drop cloth for weather or debris, and show you how the lock functions afterward so you know how to engage any added security features, like a deadbolt with a long throw or a reinforced door edge.

Worth knowing
If you call from Northeast Philadelphia we drive out from Havertown and bring the parts and tools we commonly use for houses in the area. While you wait it helps if you can unlock a different door for access, move pets into another room, and have any keys you use most handy. Tell us the door material (solid wood, hollow core, metal clad) and whether the strike has visible screws or has been shimmed; these details speed diagnosis and let us bring the right replacement parts for homes in Northeast Philadelphia and nearby areas such as Mayfair.
