When do you need to rekey your locks in Perth?

You should rekey your locks when moving into a new home, if keys are lost or stolen, at the end of a tenancy, after a relationship breakdown, following a break-in, or when buying a property with an unknown key history.

How does the rekeying process work?

A locksmith removes the lock cylinder, replaces the internal driver pins with a new set that matches a freshly cut key, and then reassembles and refits the cylinder to the door. Most rekeying jobs take under an hour per lock.

The Complete Guide to Lock Rekeying in Perth: What It Is, When You Need It & What It Costs

Q: What exactly is lock rekeying and how is it different from replacing a lock?

Rekeying involves adjusting the internal pin configuration of your existing lock cylinder so that the old key no longer works, and a new key is cut to match the new pin arrangement. In contrast, replacing a lock means removing the entire lock assembly and fitting new hardware.

Q: What does lock rekeying cost in Perth?

Rekeying is generally less expensive than full lock replacement, as it involves labour and new pins rather than new hardware. Costs depend on the number of locks, lock type, and whether the service is during business hours or an emergency callout.

Q: Can all locks be rekeyed, or only certain types?

Most standard pin tumbler locks can be rekeyed, but some older, worn, or heavily corroded locks may not be suitable. A locksmith can advise if replacement is necessary.

Q: Is rekeying really secure, or do I need to replace the lock entirely?

Rekeying provides the same level of security as a new lock when performed by a licensed locksmith, as it invalidates old key combinations. Replacement is only needed if the lock body is damaged or outdated.

Q: How long does it take to rekey a lock?

A single standard residential lock typically takes under an hour to rekey. Multiple locks can usually be rekeyed in a single appointment.

•Rekeying changes your lock's internal pins so old keys stop working — without replacing the hardware.
•It's typically less expensive than full lock replacement when the lock body is in good condition.
•Moving into a new home is the single most common — and most overlooked — reason to rekey immediately.
•Lost keys, a tenancy change, or a break-in are all triggers to act the same day.
•A licensed Perth locksmith can rekey most standard locks quickly, often in a single visit.

You’ve just moved into a new Perth property, or your keys have gone missing — and you’re wondering whether your home is actually secure. Rekeying your locks is the fastest, most affordable way to regain control of who can get through your front door, and most Perth homeowners don’t realise how simple the process is.

What Exactly Is Lock Rekeying — and How Is It Different From Replacing a Lock?

Same hardware, completely different key — here's how it works.

Rekeying means a locksmith adjusts the internal pin configuration inside your existing lock cylinder so that the old key no longer operates it. A new key is then cut to match the new pin arrangement. The lock body, the strike plate, and the door hardware all stay exactly where they are.

Full lock replacement, by contrast, means removing and discarding the entire lock assembly and fitting new hardware. Replacement makes sense when locks are visibly damaged, corroded, or outdated — but if your lock is in good condition, rekeying achieves the same security outcome at a lower cost. For a detailed comparison, our related guide Rekeying vs Replacing Locks: Which Option Is Right for Perth Homeowners? walks through the decision criteria side by side.

Rekeying works on most standard pin tumbler locks — the type found on the vast majority of Perth residential doors. If you’re unsure whether your lock is compatible, a licensed locksmith can assess it in minutes.

When Do You Actually Need to Rekey Your Locks in Perth?

These are the situations where waiting is not an option.

Moving into a new home is the most common trigger — and the most frequently skipped step. Previous owners, contractors, real estate agents, and neighbours may all hold copies of your keys. Our related post Moved Into a New Home in Perth? Here’s Why Rekeying Your Locks Should Be Your First Priority covers exactly why this is non-negotiable, even when the vendor hands over every key they own.

Lost or stolen keys demand immediate action. If someone finds your keys and knows your address — from a wallet, a gym fob, or a car registration — your home is exposed. Our related article Lost or Stolen Keys in Perth? Why an Immediate Lock Rekey Could Save You From a Break-In details the real risk window and what to do first.

•Moving into a new home — you can't verify who holds copies of the current keys
•Lost or stolen keys — especially if your address is identifiable
•End of a tenancy — a previous tenant may have copied their key
•After a relationship breakdown where a former partner had access
•Following a break-in or attempted forced entry
•Buying a bank-owned or estate property with an unknown key history

How Does the Rekeying Process Actually Work?

A quick, straightforward job when handled by a licensed professional.

A locksmith removes the lock cylinder from your door, disassembles it, and replaces the internal driver pins with a new set that matches a freshly cut key. The cylinder is then reassembled and refitted to the door. Most standard residential rekeys take well under an hour per lock. Our related step-by-step article How Lock Rekeying Works: A Step-by-Step Guide From a Perth Locksmith goes deeper if you want the full technical picture.

One practical bonus: if you have multiple locks across your home, a locksmith can rekey them all to operate on a single new key — what’s known as a master key setup. That means one key for the front door, back door, and garage, rather than a bulging keyring. You can explore the full range of locksmith services available across Perth to see what’s included.

Ask your locksmith to rekey all external entry points in a single visit. Rekeying only the front door while leaving the back door or side gate on the old key defeats the purpose entirely.

What Does Lock Rekeying Cost in Perth?

Honest expectations so you can budget without surprises.

Rekeying is generally less expensive than full lock replacement because you’re paying for labour and new pins rather than new hardware. The total cost depends on the number of locks being rekeyed, the lock type, and whether the job is scheduled during business hours or called in as an after-hours emergency.

Emergency and after-hours callouts attract higher rates — that’s standard across Perth’s locksmith industry. The smartest approach is to schedule non-urgent rekeys during business hours and call 0481 365 802 immediately if you’re in a situation that can’t wait, such as lost keys or a security breach. Ultimate Lock provides transparent, upfront pricing with no hidden fees.

Lock Rekeying in Perth — Your Questions Answered

Straight answers to what Perth homeowners ask most before booking a rekey.

Can All Locks Be Rekeyed, or Only Certain Types?

Most standard pin tumbler locks — the type used on the majority of Perth residential and commercial doors — can be rekeyed. Some older, worn, or heavily corroded locks may not be suitable, and a locksmith will advise you on the spot if replacement is the better call.

Is Rekeying Really Secure — or Do I Need to Replace the Lock Entirely?

Yes — when performed correctly by a licensed locksmith, rekeying provides the same level of security as fitting a brand-new lock, because the old key combinations are completely invalidated. Full replacement is only necessary when the lock body itself is damaged, outdated, or a low-security grade that no longer meets modern standards.

How Long Does It Take to Rekey a Lock?

A single standard residential lock typically takes under an hour to rekey. If you’re having multiple locks rekeyed in one visit — which is recommended for whole-home security — a licensed locksmith can usually complete a full house in a single appointment.
