I have an idea I would like coded, everyone will want it if it can be done. I live in a hot climate with a black 40d. My wife would put our three kids in the car with the ac on while she loads the shopping. I don't want a car jacking with my kids in the car! Do you know if you can code that the brake/gear change interlock can be prevented if the "where's your key, not in the vehicle" warning comes up? Cheers
