Find the right replacement gearbox for uPVC and composite doors from our range of reliable multipoint lock gearboxes.

We stock replacement centre cases and gearboxes suitable for many popular door lock brands and systems. Whether your door handle is stiff, the key will not turn correctly, or the multipoint locking mechanism has failed, replacing the gearbox can often restore the lock without needing to replace the complete locking strip.

Our range includes gearboxes with different backsets, centres, spindle configurations and locking mechanisms, helping you find a compatible replacement for your existing door lock.

For the best match, check the manufacturer, backset, PZ centres and gearbox dimensions on your existing lock before ordering.

Shop replacement gearboxes for uPVC front doors, back doors, patio doors, French doors and composite doors, with options available for a wide variety of multipoint locking systems.
