A lock change in Australia typically costs around $70 to $200 per lock in 2026 for a standard replacement during business hours, with high-security and smart locks at $250 to $700 and a call-out fee on top.
Rekeying is cheaper than replacing because the lock body stays. High-security and smart locks cost more, and after-hours or emergency call-outs carry a clear premium over a booked daytime visit.
