What are High Security Locks Anyway?!

High Security is a term that is used a lot in my line of work as a locksmith in North London . My customers often ask me what high security means when it comes to high security locks for homes. There are a number of factors that need to be considered when it comes to high security residential door locks.

If you want to achieve High Security you should consider the type of keys as well as the type of lock. You can have;

  • A high security door lock without a high security key
  • A high security key without a high security door lock
  • A high security door lock with a high security key

The latter option being the most high security option.

The factors that make a lock “high security” are as follows;

  • The lock offers optimum security to your specific property
  • The lock that has been officially tested by a respected security product test house such as Sold Secure www.soldsecure.com owned by the Master Locksmiths Association.
  • The lock is well fitted by a qualified professional locksmith

UPVC doors and Timber doors require different lock types.

There are different types of high security locks that can be used for timber doors;

  • Chubb locks
  • High security cylinder locks (as above)
  • Night latches

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.

To conclude, it probably won’t surprise you to hear that in my opinion as an experienced locksmith security is paramount and is a basic necessity. So to answer the question “Are high security locks a luxury or a necessity?” I certainly wouldn’t class the safety and security of my family as a luxury. The first thing I did when I moved into my home was to install high security locks with high security keys! I wouldn’t sleep otherwise.
