I will be bringing it back next Monday and their plan is to pull both of the other locks and find the damaged tumblers, replace them, re-key, and re-install. I did ask what they are going to do if/when they pull the two other locks and the tumblers are fine (which is what I’m expecting since I hadn’t had an issue prior to them pulling the driver’s side lock). They really just think there are more bad tumblers in the locks and it was a coincidence that they both went at the same time, and the same day the driver’s side door was fixed.
