The main door of my flat has 2 yale type locks and a Mortice lock.
The mortice lock key is the only one I ever received.
It's only when the plumber came to do some work that I realised the
possible problem of having two potentially self locking devices on the
door with no key to open them from the outside.
How do I overcome this? Will a Locksmith be able to provide the means
of making these locks fully functional, with minimum cost and work
involved, or will a complete replacement be necessary?
