What a rekey locks costs in Sydney
Rekeying locks in Sydney 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 no longer work while keeping the existing door hardware. So the cost scales with the number of barrels, and the main reason to rekey is after moving into a home, losing a key, or a tenant changing, when you want new keys without the expense of new locks.
Keying several locks alike is a popular, low-cost option in Sydney, because once a locksmith has a lock apart, keying the front, back and other doors to open with one key adds only a little per barrel and saves juggling keys. A terrace in the eastern suburbs or a strata apartment may have only a couple of locks, keeping the job small, while a larger house with many doors costs more by the barrel. Old or worn locks may not be worth rekeying and are better replaced, which a locksmith advises on, and the city's highest trade rates lift the callout. A restricted or high-security key system is a dearer specialist rekey.
Locksmithing is a service trade, and in New South Wales 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 Sydney home, the clearest way to price rekeying locks is per barrel plus a callout, much cheaper than replacement, with keying several locks alike a cheap convenience.
