I know I’m super late to this thread but I have a 1993 k1500 any help would be appreciated and I looked in the glovebox and the third code was AU3 does this mean I have keyless entry or not?What year is your Taho? OBDI & II are different.ALLDATAdiy has instructions to see if yours has remote entry.If you'll tell me the year I'll look it up.
