Has anyone tried adding an external keypad for keyless entry, such as Ford offers on their vehicles? Our old Explorer had this feature and my wife fell in love with it. She likes to be able to lock her key inside the car when she's hiking or at the beach. I know this can be accomplished on the Ascent by temporarily disabling the fob and using a code with the button on the back hatch, but that seems cumbersome for regular use. I've seen them available as an aftermarket item, such as the Essex AKE5, but I'm concerned about getting it to work in conjunction with the Ascent's proximity activated locking system.
