I just bought this accessory today. It was a little finicky entering the personal code but otherwise really simple process. I have yet to attach it though as I haven't decided where to put it. I have a red 08 Fusion. Its definitely a little bigger than the factory installed keypad but it really isn't that bad. I'm trying to decide whether I want over the door handle where the factory installed pad would go or vertically along the window like I've seen in previous year's SUV's. I think it looks pretty good in both places. What do you guys think?
