High Security Door Locks – Luxury or Necessity?

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.

 

High Security Locks

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.

 

UPVC High Security Locks

The type of lock required for a UPVC door is a Euro cylinder.

To be classed as high security the locks must be;

  • Anti-snap Read our post about lock snapping.
  • Tested to the latest British Standard TS007:2012
  • Hold no less than a 3 star British Standard rating or Sold Secure Diamond rating.

When it comes to high security locks for doors as a general rule a timber door and the locks for timber doors offer greater levels of security than a UPVC door. I will explain exactly why.

 

Timber Door High Security Locks

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.

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.

 

So from the consumers perspective the BS3621 prevents;

  • Ability to reach in and open the door from inside.
  • Destructive entry
  • Lock picking
  • Forced entry
  • Likelihood of duplicate keys in the same area.

 

BS3621 locks are without a doubt the best high security locks available.

 

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.
