Rekeying changes the lock's pins so old keys stop working, cheaper than replacing locks and perfect after moving in, losing a key, or a change of tenants. Keying everything alike to one key is a cheap, worthwhile upgrade.
Ways to save
- Rekey rather than replace if the locks are sound, it is roughly half the cost.
- Key all locks alike to one key while the locksmith is there, it is only a small extra.
- Do all locks in one visit to spread the call-out fee.

What a rekey locks costs in Perth
Rekeying locks in Perth is priced per lock barrel rekeyed plus a locksmith callout, and it is far cheaper than replacing the locks, because rekeying changes the internal pins so the old keys stop working while keeping the existing hardware. The cost scales with the number of barrels, and the usual trigger is moving into a home, a lost key or a tenant change, when new keys are wanted without the expense of new locks.
The hot, dry Mediterranean climate is kind to a lock mechanism in Perth, because the low humidity means less corrosion and seizing of an old barrel than in the humid north, so a lock is more often in good enough condition to rekey rather than replace, which can keep the job cheaper. Fine wind-blown sand can, though, work into an external lock and stiffen it over time. Keying the front, back and other doors alike adds only a little per barrel and is a popular convenience. The isolation of the WA market can add lead time for a specialist or restricted key-system component, though a standard rekey uses stock pins. Labour sits near the national average, and a double-brick home's locks are standard door hardware regardless of the wall.
Locksmithing is a service trade, and in Western Australia a locksmith works under the state security licensing that covers the trade rather than a building licence, so rekeying is not a licensed building trade but a licensed security-related service, and a reputable locksmith is insured. For a Perth home, the clearest way to price rekeying locks is per barrel plus a callout, far cheaper than replacement, with the dry climate kind to the lock mechanism.
