Yesterday the alarm kept going on and off which was weird so today I go out and try to start the 2004 Tahoe and I get an Unknown driver message and the lights flash on and off the dash panel goes off then back on and then driver 1 comes up and it starts. I shut it off and try to restart and the same thing happens. Anybody heard of this and know what to do?

 

Key fob needs retraining. Its asking because the key fob signal does not recognize the presets

 

Just ran my BlueDriver to get the codes and this what it found. Also it started right up and driver 2 came up with no issues very strange.

 

How do I retrain the fob
