We also offer a high security cylinder replacement service for PVC U and aluminium doors. Many of these products were fitted with standard lock cylinders which are extremely vulnerable to lock snapping which allows someone to gain access to your property very quickly.
We supply and fit replacement cylinders from the Ultion rage which are diamond secure which is approved by the police, British standards and the locksmiths association.
All the cylinders come with a £1000 guarantee against lock snapping (see website for details*)
All the details for the lock cylinders can be found in the download section
