Professional Lock Change Service in Glasgow and Paisley

If you need your door locks changed, A.L.S. Locksmiths provides a professional lock change service throughout Glasgow, Paisley, Renfrew and the surrounding areas. Whether you have moved into a new property, lost your keys or want to improve your home security, we can supply and fit suitable replacement locks.

We work with a range of door locks, including mortice locks, euro cylinders, rim locks and locks fitted to uPVC and composite doors.

When Should You Change Your Door Locks?

There are several situations where changing your locks is a sensible security measure.

Moving into a new home

When you move into a property, you cannot always be certain who has copies of the existing keys. Changing the locks gives you greater control over who can access your home.

Lost or stolen keys

If your keys have been lost or stolen, replacing the lock may be the best option, particularly if the keys could be linked to your address.

Damaged or worn locks

Locks can deteriorate through everyday use. If your key is difficult to turn, the lock is sticking or the mechanism is becoming unreliable, replacement may be necessary.

Improving home security

Older locks may not provide the level of protection you want. Depending on your door, upgrading to a suitable modern lock can improve security and provide greater peace of mind.

Lock Changes for Different Types of Doors

A.L.S. Locksmiths works with a variety of door types and locking systems.

  • uPVC and composite doors: Replacement euro cylinders, including snap-resistant options, and repairs or replacement of faulty locking components where required.

  • Timber doors: Replacement mortice locks, night latches and other suitable locking systems.

  • Front and back doors: Lock changes to help restore security following lost keys, a house move or a faulty lock.

The correct replacement depends on the existing lock, the door construction and the security requirements of the property. We assess the requirements before recommending a suitable option.

Choosing the Right Replacement Lock

Not all locks offer the same level of security. When changing a lock, it is worth considering the type of door, the existing hardware and any applicable insurance requirements.

For suitable uPVC and composite doors, a snap-resistant euro cylinder can help protect against lock-snapping attacks. The appropriate cylinder and any additional security hardware should be selected to suit the door and locking system.

For timber doors, the correct mortice lock or night latch depends on the existing fittings and the level of security required.

Our aim is to fit a suitable replacement rather than simply install a lock that does not match the door or its requirements.

A Straightforward, Fixed-Price Service

At A.L.S. Locksmiths, we offer fixed prices agreed for the work, with no call-out charge. We explain the work required before proceeding, so you know what to expect.

We also offer a 12-month guarantee on parts fitted, subject to our guarantee terms.
