Question about 2000 GMC Sierra
I changed my used sierra's battery and when I got power, my factory stereo locked up. The original owner can't remember the security code. Is there anyway to reset it without taking it to a GM mechanic?
Look behind the glove box, there should be a sticker with the code on it. or in the owners manual if you have one.
