Keyless ignition is a gadget that some folks like. But some of us just don't. When I put the key in my pocket, I know my vehicle is off.

I was interested in the new Bronco until I saw a pic of the dash. Is there going to be keyless on all of them?

 

Some have a warning chime to alert the driver the vehicle is not off, also you probably won't be able to lock the doors if anything is left on. The battery saving feature is supposed to prevent accessories from staying on longer than a set specified time.
Might be a good move to see and learn how the new system works, you just might like it ..

 

Sorry Bronco workshop manuals arent available yet, I have not seen this written anywhere but I would be surprised if there is not one or two low trim levels that have a physical key. It seems to be the lower trim levels that have physical keys still, of course they cost less so dealers dont stock them as much.
Just FYI the vehicles are programmed to shut off after sitting at idle in park for X time, I think you can adjust this time, they also shut off if the key is not in the vehicle for Y time, I think it has to be in park in this case, not sure though. I dont know how long X and Y are.
