What's the difference between rekeying and replacing a lock?

Rekeying changes only the internal pins of your existing lock so old keys stop working and a new key operates it - the hardware stays on the door. Replacement removes the whole lock and installs new hardware. Rekeying costs $50-$70 per lock; replacement runs $110-$300+ per lock.

When is rekeying the right choice?

When your locks are in good working condition and your concern is who holds keys: after moving into a new home, losing keys, a break-up or flatmate change, or when you want one key for every door (keyed alike). It's faster and significantly cheaper than replacement.

When should I replace locks instead of rekeying?

Replace when the lock itself is the problem: worn or sticking mechanisms, damage after a break-in, rusted external locks, discontinued hardware with no key blanks, or when you want an upgrade such as a deadbolt or smart lock.

Is rekeying as secure as replacing the lock?

Yes - for key control. A rekeyed lock is exactly as secure as it was the day it was installed, and old keys are dead. Replacement only adds security if you upgrade to a higher grade of hardware than you had before.

Can all my locks be keyed to a single key?

Usually. If your locks are the same brand or use compatible cylinders they can be keyed alike during rekeying at no extra charge. Mixed-brand homes may need a couple of cylinders swapped so everything matches.

How long do rekeying and replacement take?

Rekeying takes about 10-15 minutes per lock, so a typical home is done within 1-2 hours. Replacement takes 20-45 minutes per lock depending on the door and hardware. Both are same-visit mobile services in Canberra.
