uPVC Door Lock Upgrades

The latest estimates report that 70% of home entrance doors are now UPVC.

As the earliest multi point locks are now 30 years old, the older lock mechanisms are starting to fail. The public are frequently led to believe that the only option is to replace the existing door for a new modern door, at a cost of several hundred pounds.

Cusworth Master Locksmiths are able to offer cost effective solutions to many situations –  in most cases we are able to offer upgraded locks and security items to save the need for costly replacement doors.

TS007 Kitemark Three Star Rating

This is the most common standard – The cylinder in your door (that’s the part you put your key in) needs to withstand 5 methods of attack:tsoo7 attack

The MLA advise that the lock cylinder and door handles on your entrance doors should meet the three star standard, and protect against all these latest forms of attack. So your lock cylinder should be uprated to the TS007 Kitemark standard.

To ensure the security on your door effectively protects your home, you need a TS 007 three star solution.


You need EITHER:

A TS007 Kitemarked 3-Star cylinder

This is a new generation of cylinders with several layers of protection in-built. They are currently undergoing rigorous testing before they can be approved to this new standard. PLEASE NOTE: the cylinder must feature the TS007 Kitemark together with three stars.
