Hi Jan, Next to a door release by remote control, for lots of fun, is a remote starter.....I have had my D for four years and installed this when I got it. It gets as much of a double take as the car itself! If anyone is standing in front of it, they leap out of the way thinking it is going to run over them. I'll never forget an elderly lady in a supermarket parking lot, who had a paper bag of groceries.....she was next to the D and I did not see her or would never have pushed the button which startled her.....she dropped her bag of groceries that went all over the place including UNDER my D. I apologized and picked up the mess. She wasn't mad at me though. Usually I push the remote start button from inside the store so the car will be cooled or warmed by the time I get out there. I don't have the door release yet, but got the info from Darryl Tinnerstet. He says he enjoys walking up to the car, pop the door and without missing a stride, slide into the seat! Mostly it just takes a strong solenoid that will yank the door release from within the door...plus a lot of work! I don't "bend" like I used to or I would have one installed by now! I am almost 80 and am sitll the 12 year old boy with the first balloon tired bike in town!! Murray Vin: 05962 Lic: DMC-XII Washington State, USA
