2013 GMC Sierra - EVO-ALL w/TB box - programming?

Question

TBGM2 - programming this lil box would not work for me, due to time constraints I had to revert back to non TBGM2 install, but my question is, any tips on TBGM2 programming? Because I thought it did program, and then it failed later on.

Answer 1

I have had the same issue, what has worked for me is to install the ring around the key and connect the TB-GM2 to the EVO-ALL and transponder ring, turn one key on without starting, turn the key off and remove it, start the vehicle by remote start.

Answer 2

The only thing that can prevent it from programming was if it previously already been programmed.

 

Another something to look at, the module may have programmed but maybe it was the transponder loop that causing difficultities.
