:help:I was programming a new key fob when I accidently made the truck go into lockout. I mean suddenly there was no power at all. (absolutely as if the battery was disconnected). I tried a reset by removing a battery cable for a few minutes but no luck. I am positive it is not the battery cables causing the issue. I'm also tried another key. I called the dealer but they just wanted it towed in to repair. $$$$ Can anyone advise me-- PLEASE?

Try disconnecting both positive and negative cable and holding them against each other for about 30 seconds, this will clear all memory.
