Is your UPVC, wooden or composite door fitted with an obsolete locking mechanism? Has the gearbox failed, the lock become unreliable, or the original mechanism become difficult to source?

Don't replace the entire door just because the locking mechanism is obsolete. At A.L.S Locksmith, we specialise in replacing and upgrading faulty, worn and obsolete door mechanisms, helping homeowners restore security without the unnecessary expense of a new door.

We provide professional door lock repairs and mechanism replacements across Paisley, Glasgow and the surrounding areas.

Obsolete Door Mechanisms Replaced and Upgraded

Over time, manufacturers discontinue locking mechanisms, making replacement parts harder to find. Older multipoint locks, gearboxes and door mechanisms can become difficult to source, but that does not automatically mean your door needs replacing.

Depending on the door and the fault, we can assess the existing mechanism and identify a suitable replacement or upgrade.

Our services include:

• UPVC door mechanisms: Replacing faulty or obsolete multipoint locks and gearboxes.

• Composite door locks: Repairing or upgrading failed locking mechanisms.

• Wooden door locks: Replacing worn mortise locks and other locking systems.

• Multipoint locking systems: Finding suitable replacement mechanisms where available.

• Faulty gearboxes: Replacing failed components when a compatible alternative can be fitted.

• Door realignment: Adjusting doors where misalignment is affecting the locking mechanism.

Where the original part is no longer available, we investigate compatible alternatives rather than immediately recommending complete door replacement.

Why Replace the Mechanism Instead of the Door?

A locking mechanism can fail even when the door itself remains in good condition. Replacing the complete door may be an unnecessary expense if the problem can be resolved with the correct repair.

A suitable replacement mechanism or upgrade can help restore the door's locking operation, improve reliability and extend the useful life of your existing door.

Every door is different, so we assess the mechanism, dimensions, backset, centres and locking-point configuration before selecting a suitable replacement. Compatibility is essential for safe and reliable operation.

Professional Door Mechanism Replacement and Upgrades

At A.L.S Locksmith, we focus on practical repairs that address the underlying problem.

Our service includes diagnosing the fault, identifying a suitable replacement or upgrade, fitting the mechanism and testing the completed installation.

If your door has become difficult to lock, the handle no longer operates correctly or the mechanism has failed completely, we can assess the options available.

You don't need a new door – you may just need a new mechanism.
