The problem
A returning customer's French double back door would not open. We had changed the lock on this door a couple of years before.
What we found
This time the lock was fine. The mechanism inside the door had failed.
What we did
We replaced the whole mechanism and kept the same lock.
How long
About an hour and a half, including the drive.
Arrived in 45 mins and fixed my broken door handle lock within an hour.
