My pal just got a new F150, (2020, not brand new, but you'd never know it. I digress) it's pretty deluxe. The extra key had this gadget hooked to it, but he doesn't have any idea what its for. He's been looking through the owners manual, but so far he can't figure it out. (The button at the end isn't magnetic. he checked)
Does anyone here have any ideas?
