Do you have an aftermarket alarm installed on your truck? Sounds like you may have to take it to a dealer, should be pretty easy for them to figure out since it won't start and it's not an intermittent problem!

Sorry man, I love being able to fix most everything myself, but from what you describe is going on, I would be looking towards the dealership if I was in your situation!! Good luck with it all and please report back with your findings!!
