Commercial Lock Repair

Commercial Lock Repair, step by step.

What this covers

When a business door key turns hard, sticks, or stops turning, we look at the parts at the door. We repair worn cylinders, loose trim rings, bent latches, and broken pieces inside the lock case. We also replace failed parts on business doors when the key no longer catches or the bolt will not move cleanly. In Mid-Missouri, that work can involve a storefront handle, an office knob, or a mortise lock with a worn faceplate. The goal is to restore the parts you use every day.

How the work goes

We start with the key, the latch, and the way the door closes. A loose screw, a damaged cylinder, or a broken spring can each point to a different repair. Some jobs need a simple part change. Others need a full teardown of the lock body and a careful reset of the moving pieces inside. We match the repair to the wear we see at the door, so a sticking key, a sagging handle, or a deadbolt that drags gets the right fix for that opening.

Where it stops

We do not cut, reshape, or repair the door, jamb, or frame. If the wood or metal at the opening is the problem, that is outside this service.

Worth knowing

Before you call about commercial lock repair

You may ask if the worn cylinder can stay in the door. If the key drags or the plug sticks, we inspect the face of the cylinder, the tailpiece, and the retaining screw. A bent cam, a cracked plug, or a stripped housing gets replaced. If the body is sound, we may keep it and change the part that fails. You also may ask whether the same key can stay in use. If the key pattern still matches the new cylinder parts, we set it up for that key.

You may ask what gets changed when the latch will not catch. We check the latch bolt, the spring inside the case, and the trim around the key slot. If the bolt hangs up or the spring is weak, we replace that latch unit or the worn case parts. If the key turns but nothing moves, the problem may be in the cam or the tailpiece, not the key itself. You may also ask if the lever handle stays. If the handle moves freely and the spindle is sound, we leave it and repair the failing part at the door.

You may ask if a broken key means the whole lock needs to go. Not always. We look at the broken blade, the keyway, and the cylinder face. If a fragment sits in the slot, we remove it and check for burrs or bent parts around the opening. If the cylinder is worn past that point, we replace it. You may ask about new keys. When a new cylinder goes in, we set the keying to match the door’s needs and test the turn at the knob, thumbturn, or lever.

FAQ

Commercial Lock Repair questions

What questions should I ask on the phone about my business door lock, and why does each one matter?

Ask whether the key turns, whether the latch sticks, whether the thumbturn feels loose, and whether the deadbolt throws partway. Those details tell us what you can see at the door and what may be worn inside the lock. We can also hear whether the cylinder binds or the key catches on the way in. That helps us plan for the parts that may need replacing.

If my key goes in but will not turn, what should I tell you?

Tell us if the key stops at the same spot, if it wiggles, or if it will turn only with force. Those signs point to wear in the cylinder, the tailpiece, or the latch side of the lock. We listen for a dry scrape, a hard stop, or a loose feel at the knob or lever. That helps us narrow the repair before we look at the door.

What if the lock turns, but the bolt or latch does not move right?

Tell us whether the bolt sits partly out, whether the latch drags, or whether the lever springs back slowly. We use that to check the moving parts inside the case and the pieces that drive them. A broken cam, worn spindle, or weak spring can leave the face of the lock moving while the bolt stays put. That changes which parts we replace.

How do I know whether my door needs repair or a part replaced?

You may see a loose cylinder, a bent keyway edge, or a knob that drops too low when you press it. We look for broken springs, worn latches, stripped parts, and cracked covers inside the lock body. If one piece has failed, we replace that part instead of chasing the same problem again. The key and the latch tell us where to start.
