Lock Repair in Johannesburg
Locks tend to fail slowly. The key takes a wiggle, then two, then a shoulder against the door; the latch needs a slam; the gate key only works if you lift the gate. Catching it at that stage usually means a repair rather than a lockout. We're a mobile locksmith that repairs door, gate and safe locks on site, and we'll tell you plainly when a repair isn't worth the money and a replacement makes more sense.

Faults worth getting looked at
- The key is stiff or gritty going in or turning.
- The bolt drags or only throws partway.
- The latch doesn't catch when the door closes. See why a door won't latch.
- A multipoint lock won't engage when you lift the handle. Our guide to multipoint locks that won't engage explains the common reasons.
- A gate lock has seized or turns without moving the bolt. Read pedestrian gate lock problems.
- The handle droops or springs back slowly.
- The cylinder moves in the door when the key turns.
Is it the lock or the door?
A good share of "broken lock" calls turn out to be door problems. Hinges loosen, timber swells in the rainy season, aluminium frames shift, and suddenly the bolt is a few millimetres off the strike plate. The lock then has to fight the door every time. The technician checks the alignment before blaming the lock, because adjusting a door or moving a strike plate costs less than fitting new hardware.
Repair or replace: how we decide
| What we find | Usual outcome |
|---|---|
| Door has dropped or the strike is out of line | Adjust the door or reposition the strike |
| Loose cylinder, handle or fixing screws | Tighten or refit, replace any missing parts |
| Dirty or dry mechanism | Clean and service as the lock maker recommends |
| Broken spring, follower or gearbox part | Replace the part if it's available |
| Lock body worn out or obsolete | Quote for a replacement lock |
What not to do in the meantime
Don't force a stiff key. Snapped keys almost always start with someone leaning on one. Avoid squirting cooking oil, general household spray or grease into the lock: some products collect dust and make things worse, and many lock makers specify what should and shouldn't be used. If a lock gets harder to use every day, stop using that door if you can and call us. A key broken in the lock is a bigger job than a service.
Gates and security doors
Pedestrian gates and trellis doors live outside in sun, dust and storms, so their locks wear differently from indoor ones. Hinges sag, the gate drops, and the lock bolt starts rubbing on the keep. We check the gate's hang as well as the lock. For a padlocked gate or burglar bars, our guide to choosing padlocks for gates and burglar bars may help.
What a repair costs
R250 call-out fee. The technician assesses the job on site and gives you the price before any work starts. Nothing is done until you agree. The price depends on what's wrong, any part needed and how long it takes. If a repair isn't sensible, you'll hear that too. EFT, cash or card.

Where this service is available
We provide lock repairs as part of our mobile locksmith service across Johannesburg. Areas we're often asked about include:
Questions customers ask
Can you fix the lock instead of replacing it?
Often, yes. Many faults come from alignment, a loose fixing or a worn part. Where the lock itself is worn out, we'll explain why a new one is better value.
Do you repair multipoint locks on aluminium doors?
Yes. Send a photo of the edge of the door showing the faceplate and the make if you can see it. That helps us bring a matching part.
Can you repair a lock on a gate in a complex?
Yes, with the body corporate's or managing agent's go-ahead if the gate is shared property.
