What our lock change service covers

  • Moving into a new home β€” Make sure no previous owner, tenant or tradie still has access.
  • Between tenants β€” Fast lock changes for landlords and property managers, with invoices for your records.
  • Lost or stolen keys β€” New locks so the missing keys are useless.
  • Staff changes β€” Change office and shop locks when staff leave or keys go missing.
  • After a break-in β€” Damaged or forced locks replaced with stronger hardware.
  • Upgrading security β€” Swap old, low-grade locks for quality deadlocks and commercial-grade cylinders.

Residential lock change

For homes and apartments we change front, back and side door locks, deadlocks, sliding door locks and gate locks. We'll match finishes where we can and make sure every door locks smoothly before we leave.

Commercial lock change

For offices, shops, cafΓ©s and strata buildings we fit commercial-grade locks built for heavy daily use. We can work before opening or after close so your business isn't disrupted.

Lock change or rekey?

If your existing locks are in good condition, rekeying can be a cheaper way to stop old keys working. If the locks are old, worn, damaged or low quality, a full lock change is the better choice. We'll tell you honestly which makes sense.

FAQ

Lock Change FAQs

How quickly can you change my locks?

Usually the same day across inner Sydney. Call in the morning and we can often fit new locks that afternoon.

Do landlords have to change locks between tenants?

Rules about locks are set by NSW tenancy law and the lease. Many landlords change or rekey locks between tenancies for security. We provide invoices for property managers.

Can you change all the locks in an office?

Yes. We change single doors or every lock in a building, and can schedule the work outside trading hours.
