Why You May Need a Lock Replacement

Lost Keys or a Stolen Bag

Losing your keys can leave your house vulnerable to theft, especially if they were taken during a break-in. A new set of door locks removes the risk instantly. I replace cylinders, bolts, latches and rim cylinders quickly so your property stays secure.

Worn, Faulty or Sticking Door Locks

If your door lock or latch keeps sticking, slipping, or not turning smoothly, it could fail at any time. Replacing old or damaged cylinders and mortice locks is often more reliable than repeated repairs.

After a Burglary or Attempted Break-In

Burglars often damage door locks, mortice lock bodies, bolts or night latch plates. I replace damaged locks fast and ensure everything is secured to high security standards, including British Standard options.

Moving Home or Changing Tenants

If someone else has a copy of your keys, replacing your door locks is the safest course of action. I carry a wide range of door locks in stock so I can change everything in one visit.

I recently used AD locksmithing to carry work out at my elderly neighbours property. The work required was out of normal working hours. They were very helpful when I contacted them and the work was carried out very efficiently, and in a timely manner. I would definitely recommend their services and they will be the first on my list of go to companies should I require similar services in the future.

Anthony arrived promptly to align upvc french doors which would not close or lock. He was very diligent and took his time to make sure the job was done correctly. I would highly recommend AD Locksmithing.

What I Replace – Full Range of Door Locks

Euro Cylinder Locks

I replace euro cylinder locks on uPVC, composite and timber doors. This includes standard cylinders, high-security cylinders, anti-drill, and anti-snap options.

Mortice Locks and Deadlocks

Mortice locks are standard on wooden doors. I replace 3-lever and 5-lever mortice locks, deadlocks and sash locks to suit the level of security you need.

Night Latch and Rim Cylinders

I replace night latch units and rim cylinders on wooden doors, including Yale and ERA style locks. These are common on front doors and are replaced quickly.

Multipoint Locks

If your multipoint lock is jammed, slipping or won't fully lock, I can replace the cylinder and service the mechanism. If the whole unit is damaged, I replace the multipoint lock strip with a suitable version.

Padlocks, Bolts and Additional Security

I also replace and upgrade padlocks, bolts and can fit additional locking options on sheds, garages and back doors.

Interior Doors and Home Offices

For internal rooms, home offices, and storage spaces, I replace interior door locks and latches to ensure everything remains secure.

How My Lock Replacement Service Works

1. Quick Inspection

I inspect your existing door, including the lock type, cylinders, latches, and bolts. This helps me choose the most suitable replacement.

2. Removing the Old Lock

I remove the old lock, cylinder, mortice case or night latch. If small repairs are needed to the door materials or timber frame, I handle them as well.

3. Fitting the New Lock

I install the new lock, ensuring it suits the door type, security level and insurance requirements. I carry a range of brands to fit most doors.

4. Testing and Securing Your Door

I test the door, handle, latch, and keys from both inside and outside to ensure everything is properly secured.

You'll receive straightforward guidance on maintaining your new lock in optimal condition and ensuring long-term home security.

Prices vary based on the type of lock, the brand, the security rating and the door materials. Mortice locks, euro cylinders, multipoint locks, and night latches all have different price ranges.
