I've just moved into a flat-share and noticed there's a painted-over mortice lock which is part of the door handle assembly.
There is no keyhole on the door and I assume no keys for it. Is it possible for me to remove the lock and take it to a locksmith to find me a suitable key, or refit the screens and supply me with keys? How much does this kind of service cost? Would most High Street locksmiths be able to provide this service (I've noticed there's MANY in Wandsworth (worrying!))? Would it be cheaper/easier to buy a brand new lock mechanism?
