I recently bought a used 1989 Camry. Within two days of moving into a large city it was broken into by drilling through the door directly above key lock. Somehow they managed to pop the lock and get some stuff out of my trunk and also my 15 year-old battery. Would anyone know how this could be prevented? Possibly disabling the power locks? Any info would be of help, I can't be buying batteries everytime someone walks by with a drill...I'd appreciate anyones help.
