Well I've been getting everything ready for shaving the door handles and I'd like to keep my keyless entry through the keypad (although now that I think about it what difference does it make). Anyway, I saw that the explorer has a vertical keypad that mounts on the door jam. Does anyone know if this keypad would work with our cars without much modification to wiring? I'd like to keep the doors smooth so mounting the keypad on the door jam would be perfect.
