My french doors are fitted with Yale cylinder locks, both sharing the same key.
I am now finding that I can only unlock the left door from the outside. And can only lock it also from the outside.
Attempting from the inside, I am finding that the key wont turn, hence wont lock/unlock.
I have always been able to lock/unlock this door from either inside or outside.
What has caused this problem ?
