Door Security & Lock Snapping

UPVC, Composite Door, Timber Door? Lock Snapping & Door Security

Nowadays all UPVC and composite doors work with a multipoint locking system which utilises a euro cylinder.

Basic euro cylinder locks are susceptible to lock snapping, in order to withstand this method of attack we recommend:

  • Upgrade your cylinder to a SS312 diamond approved lock, this being the highest standard achievable for euro cylinders.
  • Failing that – then ensure it is at least a kitemarked TS007 3 star approved cylinder

Front & Back Door Security

Does your timber door lock meet BS3621 Standard?kitemark

External timber doors should be secured using a mortice lock and / or night latch that meets British Standard BS3621. The easiest way to check whether you lock complies is to look for the British Standard Kitemark which is located on the forend of the lock.

Most mortice locks operate via a “lever” mechanism (normally at least 5 levers), however there are some which are operated by cylinders and therefore the same vulnerabilities as mentioned above may apply. However, in a domestic property it is not as common to have a euro cylinder in a timber door.

Is it a good idea to fit a Door Chain?

In short, Black Dog Locksmiths would say yes it is a good idea to fit a door chain. Fitting a door chain is a way to enhance security further. you may want to install a door chain as well as a door viewer to enable you to see who’s outside without having to open the door. If the lock on your door is capable of being operated without a key from the inside (called keyless egress) then you should consider fitting a letter box restrictor and if there is any glazing close to the lock then consider reinforcing this glass or adding security bars to stop people trying to access the lock from the outside.
