Quick answer

A rekey swaps the pins inside the locks you already have so old keys stop working and a new key opens them. In business hours it’s $195 inc GST for the first lock, call-out and 2 keys included (more keys are $7 each), then $55 for each extra lock; after hours costs more, and we agree the price before we start. It’s the quickest way to secure a home after moving in, losing a key or changing tenants. Amco rekeys on site across Perth, Western Australia.

What a rekey actually does

What happens in a rekey

Every lock has a row of small pins set to match one key. We take the cylinder out, swap those pins for a set that matches a brand new key, then refit it and test the door.

The lock, the handle and the door stay as they are. Only the key changes, which is why a rekey costs less than new locks and why every old key stops working the moment we finish.

Lane deadbolt with key inserted above a knob lock on a white storeroom door

From one of our jobs: two locks, one key

Losing the key to a door doesn’t always mean new locks. On this storeroom job the door was locked and the key had been lost, so Magnus opened the lock first. He then rekeyed both locks on the door, a Lane deadbolt and a knob lock, to match a key the customer already had. Nothing was replaced, and one key now opens both.

What it costs

What does a rekey cost?

Business hours, inc GST

A rekey is $195 inc GST for the first lock, which includes the call-out and 2 keys, then $55 inc GST for each additional lock rekeyed at the same visit.

First lock
$195, call-out and 2 keys included
Each extra lock
$55 at the same visit
5 / 6 / 7 locks
$415 / $470 / $525

After-hours costs more and varies with the time; the price is agreed before we start.

Prices checked September 2026.

Worked example: 5 locks = $195 + 4 × $55 = $415 inc GST. 6 locks = $470. 7 locks = $525.

What pushes the price higher: the number of locks on the door and gates, and any cylinder that’s worn or seized enough to need drilling instead of picking – we tell you first, then replace the barrel and key it to your existing key at no extra charge. After-hours bookings cost more too.

When to rekey

Good times to rekey

You’ve just moved in

You don’t know who still has a key to the old owner’s locks.

A key is lost or stolen

Rekey the locks it opens and the lost key is useless.

Tenants have moved out

Shopfronts, offices, warehouses and staff rekeys.

Too many keys

Put the doors on one key so you carry less.

How it works

How a rekey works

  1. Count the locks

    Front, back, side and screen doors, plus any gates or windows you want on the same key.

  2. Agree the price

    You know the cost before we start.

  3. Rekeyed on site

    We re-pin each lock, cut the new keys and test every door before we leave.

Good to know

One key or two?

Most Australian homes use Gainsborough or Lockwood key types. If your doors are one and your security screens are the other, you’ll end up with two keys after a rekey.

Changing the screen door cylinders solves it, so one key opens everything. We’ll tell you on the day whether your house needs it.

Good to know

Landlords, screen doors and cost

Landlords and property managers

Rekeying between tenants means every key the last tenant had stops working, without buying new locks. Tell us how many doors, screens and windows have keyed locks and we’ll quote before we come. See our work for landlords and property managers.

Screen doors too

A rekey is the right time to get your security screen door locks onto the same key as the front door.

What decides the cost

How many locks there are, which key brand they use, whether screen door cylinders need changing to get you onto one key, and whether it’s during business hours. The price is agreed before we start, and WA Seniors Card holders get 5% off.

Common questions

Straight answers

Rekeying keeps your lock and changes the pins inside so a new key works and old keys don’t. Replacing swaps the whole lock. Rekeying is usually quicker and cheaper.

Around an hour for most homes, which usually have 6 to 8 locks.

Usually. If your doors and screens are different brands, we change the screen cylinders so one key does the lot.

In most cases, yes. We only suggest a new lock when the old one is worn enough that replacing it is cheaper than another visit.

Yes. You can’t know how many keys the last owners, tenants or tradies still have. Rekeying is usually the cheapest fix: the old keys stop working and you keep your locks.

Most have 6 to 8, counting front, back, side and screen doors. We rekey them on site in about an hour.

Most Australian homes use Gainsborough or Lockwood locks, and they take different keys. If your doors and screens are different brands, we can change the screen cylinders so one key works both.

It depends on how many locks there are and whether they need rekeying or replacing. A typical Perth house has six to eight. In most cases you do not need the locks changed at all. You need them rekeyed, which resets the pins so old keys stop working and costs far less than new hardware. A rekey is $195 inc GST for the first lock, call-out and 2 keys included, then $55 inc GST for each extra lock, so six locks is $470 inc GST. After-hours costs more and varies with the time; the price is agreed before we start.

Yes – $195 inc GST covers the call-out, the first lock and 2 keys. Every extra lock rekeyed at the same visit is $55 inc GST.

No, and the difference matters. Changing locks means new hardware on the door. Rekeying keeps the lock and changes what key opens it. Nearly everyone who asks to have the locks changed actually wants them rekeyed.
