Changing locks in Perth: rekey or replace?
Changing the locks in Perth is one of two jobs: rekeying, at $47–$125 per lock in our Perth table (typically $68), or replacing the lock, at $125–$370 for a basic single lock (typically $230). If the lock still works and the worry is who has a key, rekeying is the cheaper fix.

Rekey or replace: how to choose
The question is whether the problem is the keys or the lock. If the lock works and you just don't know who holds a key, rekey it. If the lock itself is failing, or you want something better on the door, replace it.
| Your situation | Usually the right job |
|---|---|
| Just moved in and don't know how many keys are out there | Rekey |
| Lost a key, or a tenant or housemate has moved out | Rekey |
| Want one key for every outside door | Rekey the locks to one key |
| Lock sticks, grinds or was damaged in a break-in attempt | Replace |
| Outside door with no deadbolt | Fit a deadbolt |
| Want keyless entry or codes you can change | Smart lock |
Rekeying keeps the hardware you already paid for: the locksmith re-pins the cylinder so a new key works and every old one stops. Replacing makes sense when the lock body itself is worn or damaged, or when you are upgrading what is on the door.
Three worked totals for changing locks in Perth
| Worked job | Rows used (typical) | Total at the typicals |
|---|---|---|
| Just moved in: rekey 3 locks, cut 4 keys | 3 × $68 + 4 × $13 | $256 |
| Replace a worn front lock, rekey the other 2 to match | $230 + 2 × $68 | $366 |
| Rekey 2 doors and add a deadbolt to the front | 2 × $68 + $260 | $396 |
Each total multiplies and adds the typical figures of the rows named in our Perth locksmith table; quotes move within each row's range.
Rekeying three locks at the typical rate (3 × $68) still comes in under replacing one basic lock ($230), which is why a rekey is the first thing to ask about after you move in.
When replacing the lock is the better spend
A latch that drops, a key that only turns on the third try, a cylinder that has been drilled or forced, or an outside door with nothing but a knob set: in each case new hardware fixes something a rekey can't. A deadbolt or a smart lock is an upgrade, so price it as one rather than as a lock change.
Frequently asked questions
How much does it cost to change locks in Perth?
Rekeying is $47–$125 per lock in our Perth table, typically $68, and replacing a basic lock is $125–$370, typically $230. If the hardware is sound, a rekey is usually all a lock change needs.
Is a rekeyed lock as secure as a new one?
Yes, as long as the lock is in good condition. Rekeying changes the pins inside the cylinder, so old keys stop working and the lock is as secure as it was. If the lock is worn or has been forced, replace it instead.
Can all my locks work on one key?
Usually. A locksmith can rekey compatible locks to the same key in one visit, at the re-keying row ($47–$125 per lock in our Perth table). A lock that won't take the same key may need a new cylinder or a replacement lock.
Is a smart lock worth it instead of a new key lock?
A digital or smart lock supplied and fitted is $315–$840 per lock in our Perth table, typically $545, against $230 typical for a basic replacement. It is worth it if you want keyless entry or codes you can change; to cut off old keys, a rekey costs far less.
