Hi
I need to replace a Yale lock in my patio doors but I do not have the
key.
The dorr is currently locked.
I have reoved the lock surrounds in the hope there would be a lock
number which would enable me to order anew key but I can't see a number
.
Is it possable to get a new key without having the old one?
How do I replace the lock without having the original key?????
Cheers
