Ford had the (pin code) entry system on the door locks years ago. It's just as easy to make it work for the ignition. My phone uses either of the recognition systems you mentioned. It's setup for a finger print as that is the fastest way I can get into it without it being completely unlocked. Hope this doesn't rain on your parade.I was thinking would it possible to use a Face ID or pin code as an anti theft system to start your car?
Has somebody been down this road?
