Charge to open a BS 5 lever mortice lock and change the lock (Non Emergency)

The Millenco Mantis Mechanism is one of the more expensive lock mechanisms to replace and this will definitely be reflected in the final price you pay.  The Millenco Mantis MK1 is the only mechanism that has the unique 117/86PZ measurements that match the door handle. It may be possible to repair these locks but that is at the locksmiths discretion, as sometimes other parts of the lock may fail afterwards.  Many locksmiths feel it's best to supply a new system so they can provide a 12 month warranty.

Euro Cylinder locks are most commonly seen on residential properties with UPVC doors. The prices quoted here are for non emergency callouts on standard (Non BS) euro locks.  If you have lost the keys, and the door is locked, there will usually be an extra charge depending on the labour involved. In an emergency or out of hours situation, the prices will usually increase around 25 %.  British Standard locks will usually be dearer also.
