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 Darwin
Rekeying locks in Darwin 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. Labour rates among the highest in the country lift the callout, and the remoteness can add freight and lead time to a specialist lock component. The cost scales with the number of barrels, with moving in, a lost key or a tenant change the usual trigger.
The tropical climate is hard on Darwin locks, because the wet-season humidity and the salt-laden coastal air corrode and seize an external lock barrel fast, more so than almost anywhere, so a coastal or exposed lock may be too corroded to rekey and need replacing with a corrosion-resistant one, which affects the cost. A well-sealed, maintained lock rekeys better. Keying the front, back and other doors alike adds only a little per barrel. Darwin's transient population and rental turnover make rekeying between tenants a common job, and the remoteness means a hard-to-source restricted key component can delay a job. A modern home with standard locks is a quick rekey despite the high callout.
Locksmithing is a service trade, and in the Northern Territory 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 Darwin home, the clearest way to price rekeying locks is per barrel plus a callout, with a corrosion-seized lock often needing replacement and remote freight a factor.
