Lock Replacement in Johannesburg
Some locks have done their time. Others are fine mechanically but the wrong people have keys to them. Either way, a new lock or cylinder is the answer. As a mobile locksmith we bring the hardware to you, fit it to the existing door where possible, and test it with you before we go. If you'd rather know your options first, the technician talks you through them on site.

Reasons people change locks
- Keys lost or stolen, especially if they were with something that shows your address.
- Moving into a home where you can't know who still holds keys.
- A tenant, employee or ex-partner who hasn't returned a key.
- After a break-in, when a lock has been damaged or the door was opened with a key. See break-in lock repairs.
- A worn-out lock that a repair won't save.
- An upgrade to a stronger cylinder, a better deadlock or a keypad lock.
What we fit
- Euro and oval cylinders, including anti-snap types, for aluminium, uPVC and many timber doors.
- Mortice deadlocks and sashlocks, lever and cylinder types, sized to the existing cut-out where possible.
- Nightlatches and rim locks, often on older doors and flat doors.
- Multipoint gearboxes and cylinders for doors that lock at several points.
- Gate and trellis locks, and padlocks for gates and burglar bars.
- Keypad and smart locks where the door suits them. Read smart and keypad door locks before choosing one.
Choosing a better cylinder
On doors that use a euro cylinder, the cylinder is the part that matters most. A cylinder sold as anti-snap is designed to keep the door locked even if the outer part is attacked, and it should be fitted so it doesn't stick far out of the handle. When we quote, we'll explain the options for your door in plain terms, without pushing the most expensive one. On older doors, a like-for-like mortice lock is sometimes the right call: see older doors, older locks.
Keys with a new lock
We don't cut or duplicate keys. Every new lock comes with the keys its maker supplies, which varies by brand. Ask how many are included when you get the quote, and plan who should hold them. Landlords and short-let hosts may want to read key control for landlords.
Flats and shared doors
If you're in a sectional title scheme, the body corporate rules may cover what you can fit on your front door, and shared gates usually belong to the scheme. Our guide to upgrading an apartment front-door lock explains what to check before you book.
Price
R250 call-out fee. The technician assesses the job on site and gives you the price before any work starts. Nothing is done until you agree. The cost depends on the lock you choose, the door, and how much fitting work is involved. Pay by EFT, cash or card.

Where this service is available
We provide lock replacement as part of our mobile locksmith service across Johannesburg. Areas we're often asked about include:
Questions customers ask
Do I have to replace the whole lock, or just the cylinder?
On doors with a euro or oval cylinder, changing only the cylinder is often enough to make old keys useless. Lever mortice locks usually need the whole lock replaced. The technician will tell you which applies.
Can one key open all my doors?
Some brands offer cylinders that share a key when ordered as a set. Ask when you call and we'll tell you what's possible for your doors. We don't cut keys to make this work.
Will the new lock fit my existing door?
Usually. We try to match the existing cut-out so the door doesn't need modifying. If it does, you'll know before work starts.
