Understanding the Difference
Rekeying changes the internal pins and key pattern of your existing lock so the old keys no longer work. It’s cost-effective, secure, and ideal when you move house or lose a key.
Replacing a lock involves installing a completely new lock body and hardware. This is best if your current locks are worn, corroded, damaged, or don’t meet Australian Standards (AS4145.2).
When to Rekey Your Locks
Rekeying is recommended when:
- You’ve moved into a new property
- You’ve lost or misplaced keys
- A tenant or contractor no longer requires access
- You want to match multiple locks to one key
Rekeying can be done quickly, without replacing your existing hardware, and gives you peace of mind that only new keys will work.
When to Replace Locks Entirely
Full replacement is the best option if:
- Locks are rusted, worn, or jam frequently
- They’re non-compliant or low-grade hardware
- You want to upgrade to deadlocks or smart locks
- You’ve experienced a break-in or forced entry
Replacing allows you to upgrade to modern, high-security options, improve key control, and refresh your door hardware’s look and feel.
