I had something interesting happen the other day. While waiting on the wife, I was standing outside and unlocked the doors with the key remote. I didn't get in the car, waiting for my wife to come out so I could lock the front door. I heard the locks on the car click. I know I didn't hit the button again. The doors locked automatically. The elapsed time between unlock with remote and the doors locking again was about 5 min.. Tried this again later, just too make sure I didn't hit the lock button. It relocked on its own. Anybody ever have this happen?
