I thought you had the code. Sorry, I’ve done automotive before and it was good money, I’ve been out of automotive for 18+ years and no desire to start trying to catch up on the technology, plus the programmers and key cutting machines are crazy expensive.? you have to get it from GM you have the license. automotive will make you a bunch as a locksmith if your willing to pursue it ! thanks and good luck.
If you want to shoot me VIN# I’ll see what I can do !
