I have a new 2021 F250 xl. I want to add an extra remote to unlock the doors without having to use the other blade key. I let my truck idle sometimes as I'm in and out alot. With my 2016 I had a smaller key ring remote (from my 2010 f150) programmed to unlock the door incase I lock the ignition key in the truck. Can I do that with this model? I don't want to start it only to be able to open the door.
