Composite door lock repair in Penistone – Avantis gearbox replacement

We recently attended a property in Penistone, Barnsley, where the locking mechanism on the customer’s front composite door had failed.
The door had become stuck in the locked position, leaving the customer unable to open it.

Using specialist locksmith tools, we carefully opened the door without causing any damage. Once open, we identified the problem as a failed

Avantis multipoint lock gearbox.

We replaced the faulty Avantis gearbox with a new one and fully checked the locking mechanism.

We also adjusted and serviced the door to ensure everything operated smoothly and securely.

During the repair, the customer upgraded their existing lock cylinder to an Ultion TS007 3-star anti-snap thumbturn lock.
This provides improved protection against lock snapping, a common method used by burglars to attack vulnerable door locks. The thumbturn also allows the door to be unlocked from inside without using a key.

We completed all work during the same visit using parts carried in our mobile workshop.

The customer was very pleased with the completed repair, which comes with our two-year parts and labour guarantee.
