Target might have the thief on camera at the register.
Not sure how they got in your car. What kind of lock do you have? Can a fake key be made or hacked?
My hubby is not allowed to have my key with the clicker thing in his pocket. When he walks, the key lock clicks unlocking our car, without him knowing. (Same thing happened when we were younger and he had the garage door opener in his pocket....... open, close, open, close, open close every stinking time he used the lawn mower and moved forward. (yes................ many years ago we had a lawn and he mowed it..... I know very unirvine like but it was years ago when people did mow their own lawns). I couldn't figure out how our car was always unlocked when I KNOW I locked it and then one day I heard it click when we were walking to a store and bamm......... knew it was just like that garage door opener years ago.
