Lost Your House Keys in Gauteng? Rekey or Replace the Locks?

Losing a house key does not always mean replacing every lock. The first question is whether someone who finds the key could connect it to your home. The second is whether your existing locks are still in good condition. Those answers help a locksmith decide whether rekeying the affected locks is sensible or whether a lock change is the better option.

If you are locked out now, move somewhere safe, avoid forcing the door, and call PM Locksmith on 078 780 9046. Tell us your Gauteng suburb, which entrance is affected, and whether you have any other way in. Be ready to show that you are authorised to enter the property.

What to do first when house keys go missing

Take a few minutes for a focused search: check the bag or jacket you used last, the car, and the places where you normally put keys. Ask anyone at home whether they moved them. If a trusted person holds a spare, find out whether they can bring it to you.

Then think about where the key was lost. A loose, unmarked key that may still be inside your home is different from a key lost with a handbag, ID, address label or documents showing where you live. If the key may have been stolen or can be linked to your address, treat the access risk as more urgent even if you still have a spare.

Do not post a clear photo of your key or your address while asking online whether someone found it. If you cannot get inside, do not damage the door or lock trying to solve the problem yourself.

Rekeying versus replacing a lock

Rekeying changes a suitable lock cylinder so that a new key operates it and the old key no longer opens that cylinder. It may be a practical choice when the hardware is sound and your main concern is that a missing key could still be used. It does not automatically change every other door or gate that the old key might open.

Replacing a cylinder or lock may make more sense if it is worn, damaged, unreliable, cannot reasonably be rekeyed, or no longer meets the access needs of the property. Sometimes only the cylinder needs attention; a locksmith can assess whether a larger lock change is necessary.

• Key missing, lock working well: ask whether the affected cylinder can be rekeyed.
• Key lost with your address or possibly stolen: ask about securing every entrance it can open promptly.
• Lock sticking, loose or damaged: ask about repair or replacement rather than rekeying alone.
• One key opens several doors: check each affected cylinder, not just the front door.

The right choice depends on the actual lock. Ask the locksmith to explain which doors the proposed work covers and to test the new keys before leaving.

Check every entrance the missing key could open

Make a quick list: front door, back or side door, security gate, garage access and any outbuilding. If the same key opens more than one lock, changing one cylinder may leave another entrance accessible. A gate remote, keypad or other electronic access device is a separate issue; changing a door lock will not automatically disable it.

If you rent or live in a managed complex, speak to the owner, agent or building manager about authorisation and access arrangements before work starts. If you have moved into a new property, our move-in lock checklist covers the wider key-control questions.

What to send when asking for a quote

A useful WhatsApp message includes:

• Your suburb and whether you are currently locked out.
• Whether the missing key may be linked to your address.
• Which doors or gates it opened, and roughly how many locks are involved.
• Whether a spare exists and whether any lock is damaged or sticking.
• A clear photo of the door hardware if requested, without your house number or a close-up of a key.

The cost depends on the lock type, number of affected entrances, whether new hardware is needed, the callout location and the time of the job. Ask for the scope and price to be confirmed before work begins rather than assuming that every lost-key job needs a full set of new locks.

Can an old key still work after rekeying?

A properly rekeyed cylinder should work with the new key and stop accepting the old one. That only applies to the cylinder that was changed. If the missing key also opened another door, that other lock needs its own assessment.
