Hi,

I have an up and over garage door with bog standard "locking mechanism"
comprising of a small key lock and two side metal bars.

I'm conscious of how poor the secutity of the locking mechanism is.

So I'd like to fit some extra locks. The only proviso is that the lock
must be able to be operated by key on both sides of the garage door.

I don't mind fitting said locks to the actual garage door (of metal
construction) or to the door frame (which is made of wood.)

Regards,

Stephen.
