How Much Does Lock Rekeying Cost in Perth? (2026 Guide)

Perth's housing stock creates a rekeying situation you won't encounter at the same scale in Melbourne or Brisbane. The overwhelming majority of metro homes, from Morley to Rockingham, have both a solid wooden entry door and a separate aluminium security screen door in front of it. Each door has its own lockable cylinder. That means moving into a new property, or changing keys after a break-up or lost key, typically means rekeying two cylinders at the front door alone, not one.

Add a back security screen, a side gate, or a granny flat door, and the cylinder count climbs quickly. One Perth Reddit user noted paying around $100 callout, $40 per rekey, which aligns with the lower end of market data for a straightforward single-lock job. A more realistic figure for a standard three-lock Perth home (front screen, front door, rear screen) would land closer to $250 to $350 during business hours once the callout is included.

Perth's spread-out geography also plays a role. The metro area stretches roughly 90 kilometres from Joondalup in the north to Rockingham in the south. A locksmith based in Subiaco attending a job in Armadale will often charge more than the base callout rate to account for travel time. If you live in outer northern or southern suburbs, factor in the possibility of higher travel fees and longer wait times, especially for non-emergency bookings.

With 72 rekeying businesses operating across the Perth metro, you have real options, but the market here is different from Sydney or Melbourne. Perth's isolation means fewer national locksmith chains have a strong foothold. Independent local operators dominate, and that generally works in your favour in terms of customer service and price flexibility, but it also means pricing is less standardised.

The quality of operators in Perth is notably high. Sheehan Locksmiths holds a 4.9-star rating across 934 reviews, which is an impressive signal of consistency across a large volume of jobs. Atlas Lock and Key, a mobile locksmith, carries a perfect 5.0-star rating from 599 reviews. Fort Locks (4.9 stars, 318 reviews) and Krazy Keys (4.8 stars, 410 reviews) round out a strong local field. These ratings reflect the Perth market's reliance on word-of-mouth reputation, since locals tend to return to and recommend businesses they trust.

All locksmiths in Western Australia must hold a Security Agent's Licence under the Security and Related Activities (Control) Act 1996, administered by WA Police. Always confirm a tradesperson is licensed before they handle your locks. It's a quick check that protects you legally and practically.

Perth summers are genuinely brutal on locks. Sustained 40°C-plus temperatures cause uPVC door frames to expand and warp, which can misalign the lock cylinder relative to the strike plate. In these cases, you might find rekeying alone doesn't solve a stiff or non-functioning lock. The locksmith may need to adjust the door alignment or replace the cylinder entirely, adding to the cost.

Electronic smart locks and keypad deadbolts are also vulnerable. Battery life drops sharply in extreme heat, and some electronic components can fail outright. If a lock misalignment or battery failure is the underlying problem, rekeying the mechanical cylinder is only part of the solution. A good locksmith will diagnose this on arrival, but be aware that a simple rekey quote may grow once the door is inspected.

Perth also has a notable FIFO (fly-in, fly-out) workforce. Workers returning from weeks on mine sites occasionally find locks seized from disuse, or discover keys were lost or distributed to maintenance contractors during their absence. This drives a specific type of emergency rekeying demand, often in suburbs with high FIFO populations like Baldivis, Ellenbrook, and parts of the northern corridor. If you're in this situation and need same-day service, 93% of Perth's rekeying businesses offer 24/7 emergency availability, though you'll pay the after-hours premium.

Rekeying changes the internal pins of an existing cylinder so old keys no longer work. Replacing a lock means fitting an entirely new lockset. The mechanical outcome is similar, but the cost difference is substantial.

A decent replacement lockset costs $200 to $300 before labour, and that's before considering the matching security screen cylinder. Rekeying the same lock typically costs $30 to $55, with no hardware to purchase. For most situations, including moving into a new property in Fremantle or Midland, rekeying is the smarter spend unless the lock itself is damaged, low-quality, or more than 15 years old.

There is one important caveat: if the existing lock is a basic builder's-grade cylinder (extremely common on Perth's large volume of 1990s–2010s brick veneer homes), some locksmiths will recommend replacing rather than rekeying it. A worn cylinder that has been rekeyed multiple times can develop play in the plug, making it easier to pick or bump. In those cases, the higher upfront cost of a quality replacement cylinder is a reasonable investment.
