Rekey vs Replace: Lock Cost Calculator for Adelaide
How this estimate works
The rekey estimate is a per-barrel cost for each external door, plus a callout, with a small addition per door if you want everything on one key. The replace estimate multiplies your door count by a per-door supply-and-fit cost for the lock quality you choose, plus a callout.
Each is shown as a range, and the tool recommends the cheaper path, unless your locks are damaged, in which case replacing is the safer call regardless of price.

Frequently asked questions
Is rekeying cheaper than replacing?
Usually, yes. Rekeying reuses your existing lock hardware and only changes the internal pins, so you pay per barrel plus a callout rather than for new locks and fitting. If your locks are worn or damaged, replacing can be the better value.
When should I replace instead of rekey?
Replace when your locks are damaged, insecure or old, or when you want a security upgrade like high-security deadlocks. Rekeying a lock that is already failing just resets a weak point.
Can all my locks be keyed alike?
In most cases, yes, provided the locks are compatible. Keyed-alike lets one key open every external door. The calculator adds the small per-door cost for this option so your estimate stays accurate.
