My silverado won't start and it's not the key fob

Brandy Medsker · May 8, 2022

I've been having problems with my truck not starting because the truck isn't registering the key fob. Usually if I get the alarm to go off I can start it after. The dealership couldn't find anything in the day they had it probably because there isn't a code. The problem has progressed. While I was driving earlier one by one the tire sensors went out until they were all out. I parked at home and tried to lock the truck with the door button but it wouldn't work. Now my truck won't start and setting off the alarm doesn't fix the problem.

Welcome to the site.

Could you share some more info about your truck?

Are you the original owner, year, model, trim level, mods, miles, and any other thing you can think of?

Otherwise we will all just be guessing like you are.

I had a similar issue with my prior RAM 1500 that the dealership couldn't figure out. I had changed my 3rd brake light, reverse lights and cargo lights to aftermarket LEDS. The cheaper LEDs I had used were causing radio interference which interrupted the signal from the key fob. Not sure if you have aftermarket LEDs in the truck but that could be a place to start.
