You need to reset the security system.
This is what you need to do. This will take 33 minutes to do. If you have a battery charger hook it up to your battery while doing this.
Get a watch, then get in you truck and shut the door and make sure everything is off.
Now turn your key on for a 11 minutes only, do not start. After 11 minutes turn your key off and then back on for 11 minutes again. After 11 minutes do it 1 more time 11 minutes only. For a total of 3 times. After the last time when you turn the key off, then start your truck.
Before you do this, check the security fuse in the fuse box on the corner of the driver's side dash, make sure it is good. ONLY 11 minutes each time, no longer and no less 11 MINUTES EACH TIME.
There is a problem with the charging system.
