There are two major advantages of installing “high security locks”. Firstly, a High Security Lock cannot be picked, bumped or tampered with, an intruder would be forced to use some other means such as drilling the lock with a high powered drill and high end bit or cutting it off with a torch, and secondly, either method would be arduous and time consuming, neither of which is attractive to a potential intruder! They are highly likely to be deterred and to go and seek easier opportunities.

For a timber door lock to be classified as a “high security door lock” it must carry the British Standard 3621 kite mark. This is the minimum requirement for most insurance companies.

What is a British Standard 3621 Lock?

  • It can be deadlocked and the key taken away from both sides.
  • It prevents access or exit through the door without the use of a key.
  • The case and the bolt are resistant to drilling with standard tools for at least 5 minutes.
  • It has a mechanism that prevents tampering (picking).
  • The bolt must project into a steel keep by 20mm at least.
  • The locking bolt can take a sideways force of up to 10kg.
  • There should be at least 1000 different key cuts for the lock type before a key is repeated.
