Electrical Issues

[2020 Blue Powerwagon]

2020 Power Wagon - my issues started with the key fob unlock working sporadically.... Then it started with not unlocking with the fob if I used the remote start and would say the key fob has left the vehicle, even though I am in the drivers seat..... Now it will turn a number of times before starting and once it starts, the next time you try to start it will not turn over - like the battery is dead. Took it to the local Ram dealer and they could not find any errors. I went to a parts center and they installed a new battery and checked the alternator - everything looked good. they tested the old battery and it was still reading 12v. The person who installed the battery suggested I let it run for awhile so the truck can recalibrate.... I hit the remote start, the truck started and within 45 seconds powered off. I am at a loss, no error codes. I called Ram and was told the key fob not in the vehicle was a known issue, but none of the other stuff was. Any thoughts?

As dumb as it sounds, have you replaced the battery in the key fob? Check the battery contacts inside the fob when you do. Might have to tweak them so they're tight.
Like all fobs, they're just cheap garbage.
