No PAAK on Pro and XLT, and optional on Lariat:I would imagine they follow their Mach E example. 1 FOB and Phone as a Key. PAAK is exactly what it sounds like, your phone is your key. You use the FordPass app and link your phone through the app to the vehicle. As long as you have the app open and carry your phone you get access to the vehicle. There is also a backup start code that you create in the event your phone dies or is lost. You also have the key pad on the door for entry.
My experience with PAAK has been fine, others have had issues that render it useless for them. For me and the wife, I'd say we are 99% issue free with it
And as I said earlier, no keypad on Pro's door.
