Given a close relative with a propensity for locking the keys in the car, James tried a variety of Slim-Jims, Lock-picks, and other tools to gain forcible entry to his own car before he decided to go high-tech. Fortunately, he drives an older-model Chrysler and was able to wire in parallel to the door lock a momentary switch hidden inside a drilled hole on the driver's side mirror. He discovered Fords to be a tad more burglar-proof, requiring the addition of an in-line relay to activate the door lock.
