'01 4.4 with 75K and I want to know if I can manipulate the door lock behavior and eliminate electrical system use when key is off. With the door locks, I would like the doors to unlock when I shut off the car. The double pull to get out of the vehicle is maddening. I've noticed that the GPS periodically spins up when the key is off. Is there a way to reprogram the system to manipulate these things?
