Locks are mechanical devices, and like everything mechanical, they wear out. The deadbolt that used to glide smoothly now needs to be wiggled into place. The front door lock occasionally refuses to turn at all. The back gate lock has rusted solid after one too many Perth winters. Locksmith Ninja Perth repairs and replaces locks of every type, restoring smooth operation and reliable security to your property.
Wherever possible, we'll repair before we replace — saving you money and reducing waste. But when a lock has reached the end of its service life or no longer meets modern security standards, we'll explain your replacement options clearly and fit the new hardware on the same visit.
When repair isn't viable — or when you want better security — we replace locks with a wide range of trusted Australian and international brands. Whether you're after a discreet entry-level deadbolt, a high-security restricted key cylinder, or a sleek modern digital lock, we'll match the hardware to your door type, security needs, and budget.

Our team is trained to diagnose the actual cause of a lock problem rather than defaulting to "you need a new one". Often, the real fix is a quick clean and lubrication, a re-pin, or a small adjustment to the strike plate. We'll always present the cheapest workable solution first — and only recommend full replacement when it's genuinely the right call.
In many cases, yes. We can extract the broken portion of the key and, if the lock itself isn't damaged, simply cut you a new key on the spot. If the cylinder has internal damage, we'll explain your repair vs replacement options.
Quality residential deadbolts usually last 10–15 years with normal use, but exposure to weather, salt air, and heavy daily use can shorten that. If your lock is more than a decade old and showing signs of wear, replacement is often more cost-effective than repeated repairs.
Often yes — we can rekey new replacement cylinders to match your current key, so you don't end up carrying multiple keys around. This works best when sticking with the same lock brand or compatible families.
