Timber door locks
There are two main types of lock found on timber doors:
  • Night latches
  • Mortice Locks

Night latches are commonly referred to as Yale locks.  If you have lost your keys or it is only the cylinder

which is damaged we will  only change the cylinder, which is cheaper than replacing the entire lock. If the lock

body is broken or damaged we will attempt to repair it, if this is impossible we will replace the entire lock. We 

can fit night latches to new doors, or upgrade your existing lock to BS3621 one. At the very least the lock

should automatically deadlock so that the latch can not be 'slipped' - as seen being done in all the films with a 

credit card etc. As locksmiths we would recommend that all night latches meet BS3621 standards, as

recommended by the police and insurance companies.


Mortice locks come in various types, including rim mounted ones for thin doors. Insurance companies

usually insist on a five lever mortice lock which meets BS 3621 standards. As locksmiths we would always 

advise to have a BS approved five lever mortice deadlock or sashlock fitted. Many houses still have 2 or 3 

lever locks fitted to external doors. These can be replaced at a reasonable cost and the security of your home 

will be greatly improved. Mortice locks can also be operated by a cylinder, in which case we recommend a 

snap safe or anti snap and anti bump lock cylinder.

We also supply and fit door chains, door restrictors, door viewers, numerals, knockers, and letter boxes.
