Rekeying in Carnegie
Rekeying alters the internal arrangement of a lock so that the previous key no longer operates it and a new key does. The hardware on your door stays exactly where it is.
It is the appropriate option when the hardware is sound and the real concern is who might still hold a working key.

Rekeying · Carnegie VIC
What it involves
In practice
Every job is different, so this describes the shape of the work rather than a fixed procedure applied regardless of what we find.
- 01
Confirming the hardware can be rekeyed
Most conventional cylinders can. Some products, and some worn or damaged mechanisms, cannot be sensibly rekeyed and are better replaced.
- 02
Changing the internal arrangement
The cylinder is serviced so it responds to a different key. The old key will no longer operate that lock.
- 03
Keying locks alike where practical
Where the hardware allows, several locks can be arranged to work from the same key, which reduces the number of keys people carry.
- 04
Testing and issuing new keys
Each rekeyed lock is tested with the new key from both sides of the door before handover.
Worth knowing
Before you arrange anything
Rekeying does not upgrade the hardware
If the lock was already worn, loose or unsuitable, it will still be worn, loose or unsuitable afterwards. Rekeying changes the key, not the condition.
Count the keys first
It helps to know how many keys are in circulation and how many you actually need. That determines how many new keys are cut.
Replacing fits new hardware to the door. Rekeying keeps the existing hardware and changes which key operates it. Rekeying addresses key control; replacement addresses the condition or suitability of the hardware itself.
