Standing at your front door wondering whether to rekey or replace your locks? It’s one of the most common questions Gold Coast homeowners ask us — and picking the right one can save you a good chunk of money. In this guide we’ll break down exactly what rekeying and replacing a lock actually involve, when each option makes sense, and which one is cheaper for your Gold Coast home.
Rekey vs Replace: What’s the Difference?
The two sound similar but they’re very different jobs. Rekeying keeps your existing lock hardware and simply changes the internal pins so your old key no longer works and a brand-new key does. The lock stays on the door — only the “code” inside it changes. Replacing means removing the entire lock body and fitting a completely new one.
Here on the Gold Coast, most homes use Lockwood, Yale or Dormakaba hardware, and the vast majority of those locks are perfectly good candidates for rekeying. If the lock still turns smoothly and isn’t damaged, there’s usually no reason to throw it away — a rekey gets you the same security outcome (a fresh key, old keys dead) for less than the cost of new hardware. Because a rekey is quicker and uses no new lock body, it’s almost always the cheaper of the two options.
When Rekeying Is the Smarter Choice
Rekeying is usually the winner in these Gold Coast scenarios:
- You just moved into a new home or unit — you have no idea how many old keys are floating around (previous owners, tradies, real estate agents). A rekey kills every old key overnight.
- You lost a key or had one stolen — rekey and the lost key is instantly useless, no need to buy new locks.
- A tenant or flatmate moved out — landlords across Southport, Robina and Surfers Paradise rekey between tenancies to keep every property secure.
- You want all your doors on one key — a locksmith can rekey multiple locks to match a single key, so you’re not juggling five different keys on the ring.
In all of these cases the hardware is fine — the only “problem” is who might still hold a working key. That’s exactly what rekeying solves, and it’s why it’s our most-requested job for Gold Coast homeowners.
When You Should Replace the Lock Instead
Sometimes rekeying isn’t enough and a full replacement is the right call:
- The lock is worn, sticking or faulty — if the mechanism is failing, no amount of rekeying fixes it. A new lock restores smooth, reliable operation.
- You want to upgrade security — moving from an old builder-grade lock to a high-security deadbolt, a keyed-alike system, or a smart lock means new hardware.
- There’s been a break-in or attempted forced entry — damaged locks and strike plates should be replaced, not just rekeyed.
- The lock is old or mismatched — if your entry set looks dated or doesn’t match a renovation, replacement gives you both security and a fresh look.
A good Gold Coast locksmith will always tell you honestly which one you actually need — we won’t sell you new locks if a rekey does the job.
Which Is Cheaper on the Gold Coast?
In almost every case, rekeying is cheaper than replacing. You’re paying for the locksmith’s time and a small set of new pins rather than the cost of new lock hardware plus fitting. The more locks you rekey to match at once, the better the value gets per door.
For honest, upfront pricing: our call-out starts from $90 and a lock change starts from $85, with the exact quote confirmed over the phone before we start — no surprises. Rekeying is quoted the same way, based on how many locks you have and the hardware brand. We never spring hidden fees on you at the door.

Practical Takeaway for Gold Coast Homeowners
Here’s the simple rule of thumb: if your lock works fine and you just need old keys gone, rekey it. If the lock is damaged, worn, or you want an upgrade, replace it. Just moved in, lost a key, or changed tenants? Rekeying is almost always the faster, cheaper fix. Lock sticking, been tampered with, or ready for a security upgrade? That’s when a replacement earns its keep.
Either way, our mobile team comes to you anywhere on the Gold Coast — from Coolangatta to Coomera — usually the same day. We’ll assess your locks on-site and give you the honest cheaper option, not the one that pads the bill.
How the Rekey Process Actually Works
People are often surprised how quick a rekey is. When our mobile locksmith arrives at your Gold Coast home, they remove the lock cylinder from the door, take out the old pins, and insert a new pin combination matched to a fresh key. The lock body goes straight back on the door — same hardware, brand-new key, old keys dead. Most single locks take around 10–15 minutes, and if you’re rekeying several doors to match one key, we do them all in the same visit.
Because everything happens on-site in our fully stocked van, there’s no need to leave your door open, drop hardware off at a shop, or wait days for a return visit. It’s one of the reasons rekeying is so popular with busy families and property managers across Burleigh Heads, Nerang and Broadbeach — it’s sorted in a single, tidy call-out.
Common Rekey vs Replace Questions
Does rekeying make my lock less secure?
No. A properly rekeyed lock is exactly as secure as it was before — you’re changing the key combination, not weakening the mechanism. If your existing lock already meets your security needs, rekeying keeps that protection while cutting off every old key.
Can you rekey all my locks to one key?
Yes, as long as the locks are compatible (same brand/keyway). “Keying alike” is one of our most requested jobs — one key for the front door, back door and garage side door means no more fumbling through a crowded keyring.
Is it worth replacing an old lock with a smart lock?
If you want keyless entry, remote access or codes for tradies and guests, upgrading to a smart lock is a genuine step up — and that’s a replacement, not a rekey. We can advise on reliable models suited to Gold Coast homes and coastal conditions.
