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

Adelaide locksmiths almost universally price rekeying as two components: a callout or service fee to get the tradesperson to your door, and a per-lock charge for the actual work. Some businesses advertise the callout fee alone as the headline price, so it pays to ask for a full quote before confirming.

One Adelaide resident on Reddit reported paying $110 per lock for a standard rekey, which sits in the mid-range of current market pricing. Another national thread noted a combined job of a new deadlock installation plus two rekeyed locks came to $680 total — a useful benchmark when multiple services are involved.

Adelaide has an unusually high proportion of pre-1950s homes, particularly in inner suburbs like Unley, Norwood, Prospect, and parts of Port Adelaide. Many of these properties still have original mortise locks or skeleton key mechanisms, and rekeying these is a different process to working on a modern pin-tumbler cylinder.

Not every locksmith has the tooling or expertise for heritage lock work. If your home has an ornate escutcheon plate and a long, hollow-shaft key, confirm with the locksmith before booking that they service that lock type. In some cases, particularly where a mortise lock is worn or the internal mechanism is corroded, a full lock replacement may be the more practical option even if rekeying was the original goal.

For more modern homes in outer suburbs like Modbury, Elizabeth, and Salisbury, standard pin-tumbler cylinders are the norm, and any of Adelaide's 56 rekeying businesses should handle the job without issue.

The short answer is that rekeying is nearly always cheaper, provided the existing lock is in good mechanical condition. Where lock replacement in Adelaide typically costs $70–$200 for the hardware alone (plus labour), rekeying uses your existing hardware and only changes the internal pin configuration so old keys no longer work.

The exception is when the lock itself is compromised. Older properties in Glenelg and along the beachside suburbs see higher rates of salt-air corrosion in lock mechanisms, which can make rekeying impractical on a cylinder that will fail within a year anyway. In those situations, replacing with a quality deadlock and having it keyed to match your other locks is the smarter spend.

A locksmith on a national Reddit thread put it plainly: rekeying runs roughly $30–$40 per lock in labour once the tradesperson is on site. Replacing a lock adds the cost of the hardware on top. For a tenant who has just moved into a rental in Prospect or a homeowner who has recently bought in Norwood, rekeying is the obvious first choice unless the locks are visibly damaged or outdated.

With 56 rekeying businesses operating across metropolitan Adelaide, the market is competitive without being saturated. That translates to reasonable pricing and generally good availability, but it does mean quality varies. The average rating across the market sits at 4.7 out of 5 stars, which reflects a genuinely strong local trade.

Among the most reviewed businesses, Adelaide Auto Keys Car Locksmith holds a perfect 5.0 stars from 414 reviews, making it one of the most heavily reviewed locksmiths in the city. KM Locksmiths Adelaide also carries a 5.0 rating across 223 reviews, and Loyal Locksmiths Adelaide matches that with 201 reviews. Port Locksmiths (4.8 stars, 192 reviews) and Adelaide All Times Locksmiths (4.9 stars, 172 reviews) round out the most-reviewed end of the market.

Around 82% of Adelaide locksmiths offer 24/7 emergency service, which is a higher proportion than many regional markets. Given the compact metro, most businesses can reach any suburb within 30–40 minutes, so after-hours response times are generally reliable.

Because the Adelaide market is compact rather than vast, you're unlikely to need to ring ten businesses to find one that's available. Two or three quotes from well-reviewed operators will give you a solid read on fair pricing for your specific job.

The after-hours premium in Adelaide is real, but it tends to be lower than equivalent callouts in Sydney or Melbourne. A national Reddit thread noted that emergency locksmith work should run $150–$350 depending on time of day, and that range broadly holds for Adelaide, though the lower end of that is more common here given the market conditions.

For rekeying specifically (as opposed to a lockout), emergency callouts are less common because rekeying is rarely urgent at 2am. Most after-hours rekeying requests come from people who have just had a break-in or a key go missing in concerning circumstances. In those cases, expect to pay the higher callout rate plus per-lock charges, totalling $250–$400 for a standard two-lock home.

The prices in this guide are estimates drawn from market research, local business data, and real user reports. Actual costs depend on your specific lock types, suburb, number of cylinders, and the individual business you engage. Always confirm total pricing before authorising work.
