About 6 months ago I came out in the morning to find my lock cylinder pushed all the way in and door handle way loose. I thought it was an attempted breakin and took it to my local body shop who saw the bolt had come out and fixed it. Now just several weeks ago, it happened again just over lunch, this time not quite as pushed in. Both times, the door handle was loose. This seems to be a common problem, I'm guessing from checking the door is locked by pulling on the handle. Is there a better fix other than just replacing the bolt(s) in the lock?
