If you are looking at rekeying locks in Perth, one of the first questions you may have is how much the job will cost. Rekeying is often a practical alternative to replacing your locks, especially when the existing hardware is still in good condition.
In Perth, the cost of rekeying depends on the type of lock, the number of locks involved, the time of the service and whether a locksmith needs to attend your property. Based on current published local pricing, rekeying can range from around $71 to $115 per lock, with a service call potentially added to the total.
What Is Lock Rekeying?
Lock rekeying changes the internal configuration of an existing lock so that the old key no longer operates it. Instead of replacing the entire lock, a locksmith adjusts the lock cylinder and provides keys that work with the new configuration.
This can be useful if you have:
- Moved into a new Perth home
- Lost or misplaced your keys
- Had keys given to someone who should no longer have access
- Changed tenants in a rental property
- Experienced a security concern
- Purchased a property and want better control over existing keys
- Several locks that you want to operate with a suitable key
Rekeying can also be considered for homes and businesses where the existing lock hardware is still working properly.
How Much Does Rekeying Cost in Perth?
There is no single price for every rekeying job because locks come in different designs and levels of complexity.
Sheehan Locksmiths Perth currently publishes the following rekeying prices:
| Lock type | Published rekey price |
| Lock Types #1–#8 | $71 per lock |
| Lock Types #4, #12, #14, #15 and #16 | $93 per lock |
| Lock Types #10, #11 and #13 | 77–110 per lock |
These prices are listed plus the applicable service call, so the final amount depends on the complete job rather than simply multiplying the per-lock figure.
Other Perth locksmith pricing guides also show that rekeying prices vary considerably depending on the lock and service arrangement. For example, some local providers charge a call-out fee plus a separate amount for each additional lock.
For this reason, it is sensible to ask for the total expected cost before work begins.
What Can Affect the Cost of Rekeying Locks?
Several factors can change the final lock rekeying cost in Perth.
1. Type of Lock
A basic residential lock may be straightforward to rekey, while some specialised locks, mortise locks, deadlatches, sliding-door locks or other security hardware may require different parts or additional work.
2. Number of Locks
If you only need one lock rekeyed, the cost will naturally be different from rekeying all the locks around a house.
For example, if you have several doors that need to be secured after moving house, a locksmith can assess whether the existing locks can be rekeyed and whether they can be configured to work with a suitable key arrangement.
3. Service Call
A locksmith may charge a service or call-out fee for travelling to your property. This is particularly important when comparing prices advertised as “per lock”.
A low per-lock price does not necessarily mean a lower total bill if a separate service call applies.
4. Time of Service
Normal business-hour work is generally different from emergency locksmith work. Evening, weekend and late-night attendance can attract higher charges.
If the rekeying is not urgent, arranging the work during normal service hours may help keep the overall cost lower.
5. Condition of the Existing Lock
Rekeying works best when the existing lock is suitable and in reasonable working condition. If the lock is badly worn, damaged or faulty, replacing the hardware may be a better long-term option.
Is Rekeying Cheaper Than Replacing a Lock?
In many situations, rekeying can be cheaper than replacing a complete lock, because the existing lock hardware remains in place.
However, the cheapest option is not always the right option.
If the lock is damaged, outdated or no longer provides the level of security you need, replacement may make more sense. A locksmith can inspect the hardware and explain whether rekeying or replacement is appropriate.
National Australian cost guidance also notes that rekeying is generally less expensive than replacing a lock when the existing hardware is suitable for continued use.
When Should You Rekey Your Locks?
There are several situations where rekeying can be a sensible security step.
After moving house: You may not know how many copies of the old keys exist. Rekeying gives you control over who can access the property.
After losing keys: If you are unsure where the keys went, rekeying prevents those old keys from continuing to operate the locks.
After a tenant moves out: Landlords and property managers may choose to rekey locks between occupants.
After staff changes: Businesses may rekey selected locks when employees or contractors no longer require access.
After a security concern: If you believe an old key has been copied or given to someone without permission, rekeying can prevent the old key from working.
Rekeying Locks for Perth Homes and Businesses
Lock rekeying is not limited to houses. Perth businesses, offices, rental properties, shops and other commercial premises may also benefit from rekeying.
A locksmith can assess the existing hardware and determine whether the locks can be rekeyed, replaced or arranged as part of a broader master key or access-control solution.
For larger properties, it can be useful to discuss the number of doors and the way different people need to access them before deciding on the best option.
