Oz Locks
John arrives within hours for after-hours emergencies and handles complex lock jobs other locksmiths have turned away.
The standout pattern across those reviews is responsiveness in genuine emergencies: customers locked out at 1:30am, families with exposed homes after garage cable failures, and new homeowners needing security upgraded the same day they moved in all describe John arriving within hours, often without an additional after-hours fee. Four reviewers flag an active impersonation issue — a separate business trading as 'Ozlock Mobile Services' is using a similar name and has charged customers up to $600 for inadequate work; when booking, confirm you have the correct Miranda-based contact before confirming your appointment. For anyone prioritising fast turnaround, transparent pricing, and a locksmith who'll genuinely explain your options rather than upsell unnecessary work, the evidence across those reviews is unusually consistent.

About Oz Locks
John runs Oz Locks as a sole trader and personally handles every job — meaning the locksmith who answers your call is the same person who shows up at your door. Customers repeatedly highlight his willingness to work outside standard hours: arriving at 7pm on a Friday before a holiday, 9:30pm on a Sunday, or 6pm on a Saturday to resolve urgent security issues without applying after-hours surcharges in most cases. He's particularly experienced with tricky residential scenarios — fitting replacement locks to warped 20-year-old sliding timber doors, sourcing barrels for unusual locks on new builds when other locksmiths couldn't help, and rekeying multiple locks (apartment entry, garage, and letterbox) to a single key in one visit. Beyond basic lockouts, John's scope includes deadlock installation, door handle replacement, gate locks, rekeying, and diagnosing botched work done by previous tradespeople. He consistently explains his recommendations in plain language, provides a fair quote upfront, and cleans up before leaving — habits that reviewers contrast favourably against larger locksmith companies. One thing worth knowing: a separate business has been operating under a similar name ('Ozlock Mobile Services') and impersonating Oz Locks, so confirm you're booking the right contact before confirming your appointment.
Best for: urgent residential lockouts requiring a fast same-day response, new homeowners wanting locks changed or rekeyed across multiple entry points in a single visit, and tricky lock jobs — such as unusual barrels, warped doors, or work left incomplete by a previous locksmith.

Does Oz Locks offer emergency after-hours callouts?+
Yes — multiple reviewers confirm John attends jobs late at night and on weekends and public holidays. Specific examples include a 9:30pm Sunday callout, a 7pm Friday visit before a public holiday, and a 1:30am lockout response. In most of those cases, reviewers noted no extra after-hours charge was applied, though it's worth confirming the fee structure directly when you call, particularly for late-night or Sunday jobs.
What areas does Oz Locks service?+
Oz Locks is based in Miranda, NSW, and reviews reference jobs across the surrounding Sutherland Shire area. Reviews don't specify a hard service boundary, so if you're outside the immediate Miranda area it's worth calling John directly to confirm whether he covers your suburb before booking.
Can Oz Locks rekey multiple locks to a single key in one visit?+
Yes — this is one of the services John is specifically praised for in reviews. Several customers describe him rekeying apartment entry, garage, and letterbox locks to a single key in a single visit. One reviewer also notes he sourced a matching barrel for a security screen door on order, so the keying would work across both doors when the screen arrived.
I've heard there's a fake business using the Oz Locks name — how do I make sure I'm booking the real one?+
This is a real concern flagged by multiple reviewers — a separate business trading as 'Ozlock Mobile Services' has been impersonating Oz Locks and charging customers significantly more for substandard work. The legitimate Oz Locks is a sole trader run by John, based in Miranda. When booking, confirm you're speaking directly with John and use contact details sourced from the official Google Business listing or this platform rather than through third-party search results.
What do customers say about Oz Locks' pricing?+
The consistent feedback across reviews is that John's pricing is fair and transparent — he provides a quote upfront, doesn't upsell unnecessary work, and in several cases did additional minor repairs at no extra charge (such as fixing a worn barrel or a jammed key). One 3-star review in the sample flagged that a $199 Sunday call-out fee wasn't communicated clearly over the phone, so if you're calling on a weekend it's worth specifically asking about any flat call-out fees before John arrives.
