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 Melbourne
Rekeying locks in Melbourne 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.
Melbourne's many Victorian and Edwardian period homes can complicate a rekey, because an original or antique lock, a mortice lock or a heritage barrel may be worn, non-standard or hard to source pins and parts for, so a locksmith may advise repairing, rebuilding or replacing it rather than a simple rekey, which affects the cost. Keying the front, back and other doors alike adds only a little per barrel and is a popular convenience. A modern Melbourne home with standard locks is a quick, cheap rekey. Competitive trade labour just below Sydney's keeps the callout reasonable, and a restricted or high-security key system is a dearer specialist job. The winter is no obstacle to an indoor-focused service.
Locksmithing is a service trade, and in Victoria 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 Melbourne home, the clearest way to price rekeying locks is per barrel plus a callout, far cheaper than replacement, with a period-home lock sometimes needing repair or replacement instead.
