What to Do Immediately After Losing Your Keys in Perth
- •Act the same day — every hour of delay is an open window for whoever has your keys.
- •Rekeying your locks is faster and cheaper than replacement when your hardware is in good condition.
- •Every entry point sharing the lost key needs attention — not just the front door.
- •A licensed Perth locksmith can rekey your entire home in a single visit.
- •If your keys were stolen alongside ID, treat it as an emergency and call immediately.
You’ve checked every pocket, every bag, every bench — and your keys are nowhere to be found. Whether they slipped out at the shops or disappeared with your bag, your home may now be accessible to a complete stranger. This is not a situation to leave until tomorrow.
What Should You Do in the First Hour After Losing Your Keys?
The first sixty minutes matter more than most Perth homeowners realise.
Start by retracing your steps quickly — but set a time limit. If you haven’t found them within 20 minutes, stop searching and start acting. Delaying a locksmith callout while you hunt adds hours to your exposure window.
Call a licensed mobile locksmith and book a same-day rekey. You don’t need to wait until you’re sure the keys are truly gone — if there’s any doubt about where they are, treat it as lost and act accordingly. The cost of a rekey is far less than the cost of a burglary.
If your keys were in a bag that also contained your wallet, gym fob, or any mail showing your address — treat it as a stolen keys emergency. The combination of key plus address is all an opportunist needs. Call 0481 365 802 immediately.
Should You Rekey or Fully Replace Your Locks?
The right answer depends on the condition and age of your existing hardware.
If your locks operate smoothly with no rust, stiffness, or visible damage, rekeying is almost always the right call. A locksmith removes the cylinder, replaces the key pins (leaving the driver pins and springs untouched), and cuts new keys — all without touching your door hardware. Your old keys stop working permanently.
If your locks are more than 10–15 years old or already showing wear, lost keys are the perfect trigger to upgrade entirely. Perth’s coastal climate accelerates internal corrosion — what looks minor on the surface is often far worse inside the cylinder.

Which Locks in Your Home Actually Need Rekeying?
A partial rekey leaves gaps a determined person will find.
If your lost key opens the front door, it likely opens every other external entry point too — especially if you’re on a matched-key or master key system. Rekeying only the front door while leaving the back door on the old key defeats the purpose entirely.
- •Front door — highest priority, rekey first
- •Back and side entry doors — equally critical, often overlooked
- •Garage entry into the home — a common secondary access point
- •Deadbolts and separate security locks — each cylinder needs individual attention
- •Storage sheds or workshops if the same key was used
A licensed locksmith can assess your full set of entry points in a single visit and rekey everything that shares the lost key’s profile. Our locksmith services page covers the full range of rekeying and installation options available across Perth.
What If You Don't Have a Spare Key — Can a Locksmith Still Help?
Losing your only key doesn't mean you're stuck — here's what's possible.
Yes — a licensed locksmith can work directly from your lock without needing the original key. The related article Can a Locksmith Make a New Key Without the Original? What Perth Homeowners Need to Know explains exactly how this works and what to expect during the visit.
When the locksmith arrives, have photo ID confirming your name matches the address ready. This is standard practice — a professional operator will always verify your right to access before beginning work.
If you’re rekeying multiple locks in one visit, ask your locksmith about a master key setup — one key that opens every lock on your property. It eliminates the bulky keyring problem that causes keys to get lost in the first place.

Your Lost Keys Questions — Answered Directly
Straight answers to what Perth homeowners ask most after losing their keys.
How quickly should I rekey after losing my keys?
The same day is the safest answer. Every hour you wait is an hour of potential access for whoever has your keys. Most licensed Perth locksmiths offer same-day or emergency callout rekeying — call immediately rather than waiting for the weekend to pass.
Will rekeying work if my key was stolen, not just misplaced?
Yes — rekeying is equally effective whether your key was lost or deliberately stolen. Once the pins are changed, every existing copy of your old key stops working permanently, including ones you didn’t know had been cut.
Do I need to replace my locks, or is rekeying enough?
If your locks are in good working condition, rekeying is enough — it achieves the same security outcome at a lower cost. If your locks are older than 10–15 years or visibly worn, replacement is the smarter investment and the cost difference narrows considerably.
