Rekey locks in Geelong: cost, rekey vs change locks

Rekeying vs replacing a lock

A pin-tumbler lock opens when the right key lines up a set of small pins inside the cylinder. When a locksmith rekeys a lock, they swap those pins for a new combination and cut new keys to match. The lock body stays on the door, and every old key stops working.

Replacing a lock means fitting new hardware. It makes sense when the lock is worn, damaged, low quality, or you want a stronger lock. Otherwise rekeying does the same security job for less.

When to rekey

• You've just bought or moved into a home. You don't know how many copies of the old keys exist.
• Keys are lost or stolen, especially if your address was with them.
• A relationship or housemate arrangement has ended.
• After a break-in, together with checking whether doors and frames need repair.
• You want one key for every door. A locksmith can often key several compatible locks alike.

Rekey or replace? A quick decision guide

Keyed alike: one key for every door

Many Geelong homes end up with a ring of different keys: front door, back door, screen doors, garage and side gate. A locksmith can often rekey compatible cylinders so one key opens them all, which is called keying alike. Where a lock can't be rekeyed to match, a new cylinder from the same range can be fitted.

Restricted keys for homes

Standard keys can be copied at any key-cutting kiosk. A restricted key system uses keys that can only be cut by the authorised locksmith, usually with a signed authorisation. It costs more upfront, but means you always know how many keys exist. It's popular with owners of rental properties, holiday homes and anyone who has had keys go missing before.

Moving house checklist

1. Rekey or replace all external door locks, including the garage internal door.
2. Check sliding doors and ground-floor windows have working locks.
3. Reset any garage remotes and keypad or smart lock codes.
4. Change the code on any key safe the previous owner left behind.
5. Ask for all keys to be keyed alike if you'd like one key.

Rental providers and property managers

Rekeying between renters is a quick, affordable way to keep rental properties secure. Victorian rental minimum standards require external entry doors to have a working deadlock or a lock that opens with a key from outside and without a key from inside, so a changeover is a good time to check compliance. Renters who want to change or rekey locks should check their rental agreement, tell their rental provider and give them a key.

How rekeying works

Most house locks are pin-tumbler locks. Inside the cylinder are small spring-loaded pins of different lengths. When the right key is inserted, the pins line up at exactly the right height and the cylinder turns. To rekey, the locksmith removes the cylinder, takes out the old pins and fits a new set that match a newly cut key. The lock body, handle and finish all stay the same. Only the key changes.

Signs a lock should be replaced, not rekeyed

• The key is hard to turn even with lubricant
• The lock is loose on the door or the handle wobbles
• The bolt doesn't fully extend into the frame
• Visible corrosion, especially on coastal homes
• It's a basic key-in-knob lock on an external door
• The lock has been damaged in a break-in attempt

Rekeying after a relationship breakdown

If you're rekeying because a relationship has ended or you're worried about your safety, a locksmith can usually attend quickly and rekey every external door in one visit. Victorian rental laws include specific provisions for renters experiencing family violence, including around changing locks. Consumer Affairs Victoria can explain your options, and 1800RESPECT (1800 737 732) offers confidential support 24 hours a day. If you're in immediate danger, call 000.

Smart locks and keypads

Smart and keypad locks can't be rekeyed in the traditional sense, but codes can be reset and user access removed in the app. If the lock has a backup key cylinder, that cylinder can often be rekeyed or replaced so lost backup keys stop working.

What about DIY rekey kits?

Rekeying kits are sold for some lock brands, but they only work with those specific locks, need care to avoid losing tiny pins, and don't help with deadlocks and security screens from other brands. For a whole house, a locksmith is usually quicker and not much more expensive once you count the kit.

Rekeying for property managers

Property managers across Geelong often book rekeys between tenancies. Batching several properties into one visit keeps costs down, and keying rental properties to a restricted system means copies can't be made without authorisation. Give the locksmith access instructions and the number of keys needed for each property.

How many keys should you have?

Cut only what you need: one per adult in the household, one spare kept somewhere secure, and one for a trusted neighbour or family member if you want a backup for lockouts. Fewer keys means fewer chances of one going astray.

Rekeying security screen doors

Security screen doors often have their own cylinder, which means a separate key. Many screen cylinders can be rekeyed to match your front door, so one key opens both. If the screen lock is a different brand, the cylinder can sometimes be swapped for a compatible one.

Master keyed homes and granny flats

Homes with a granny flat, home office or rented room sometimes use a simple master key system: each occupant's key opens their own door and the shared entry, while the owner's key opens everything. It's the same idea businesses use, scaled down, and can often be done by rekeying existing compatible locks.

Ways to keep rekeying costs down

• Book in business hours rather than after hours
• Rekey all doors in one visit rather than one at a time
• Tell the locksmith the lock brands in advance so they bring the right pins

Renters and rental providers

Rental providers often rekey between renters, which is a quick way to keep a property secure without new hardware. If you're a renter wanting to change or rekey locks, check your rental agreement, tell your rental provider, and give them a key. Victoria's rental minimum standards require external entry doors to have a working deadlock or a lock that opens with a key from outside.

Student rentals around Deakin's Waurn Ponds campus change hands often, which makes rekeying between tenancies especially worthwhile there. See the Waurn Ponds page.
