Whilst we make every effort possible to ensure each and every Rockdoor leaving our production line is perfect, we recognise that on very rare occasions the delivered product might fall short of the quality you’d expect. With this in mind, Rockdoor is pleased to offer the following guarantee.

Lock snapping £2,000 security guarantee

Rockdoor lock cylinders meet the requirements of the British Kitemark TS007 3* and Sold Secure Diamond testing criteria, whilst also holding Secured by Design accreditation – the Police Crime Prevention Initiative.

Our 3 star locks have built in “Active Snap Protection” technology with an advanced internal locking system that will prevent access into the inner workings of the door bolt if it has been snapped on the outside.

Our locks will remain secure after forced entry snapping attacks, and in most cases will still be operable with the key from the inside.

We are therefore so confident of our locks that we offer a £2,000 security guarantee against lock snapping that would enable a burglar into your home.

The £2,000 security guarantee only applies if all of the following conditions are adhered to.

  • Doors covered by the guarantee are deadlocked and the keys not left in the cylinder internally.
  • The products must have been fitted by a Rockdoor Trusted Installer.
  • Any claims must be made in writing within 28 days of the break-in providing details of the incident and MUST include the crime reference number provided by the Police Authority the crime was reported to.

  • The lock must be returned to Rockdoor (c/o GAP, Customer Services, Partnership Way, Shadsworth Business Park, Blackburn, BB1 2QP) for inspection with photographic evidence of the lock snapped within the door.
  • After investigation if the report confirms that the lock relating to the compensation guarantee was correctly fitted and maintained, according to our 5 star installation guideline, and failed due to a forced entry through the door the lock was fitted in, the claim will be processed within 28 days of the inspection.
  • Only one claim per installation is permissible within a guarantee period which commences at the order date.
  • Guarantee is valid for UK mainland installations and applies to domestic homeowners properties only.
  • Only available for all doors ordered after 1/02/2020
