Hints & Tips - Mortice Locks
These operate by the key lifting internal levers to varying heights to allow the bolt to throw out. The more levers a lock has, the harder it is to pick. The minimum standard you should consider is 5 levers. Those locks that conform to BS 3621 have additional safeguards: (i) The bolt contains revolving steel pins that will roll under a hacksaw blade, preventing the blade from cutting through it. (ii) The sides of the casing are drill-resistant hardened steel. (iii) The keeper that fits in the door frame is a steel box. This prevents an intruder forcing the bolt back into the lock.
