I’m also looking for how to retrieve the key code on a 1988 GMC Sierra.

Wish I found this thread before towing my 1988 GMC Sierra.

Can confirm it worked for my 2013 1988 GMC Sierra.

Can’t believe this worked on my 1988 GMC Sierra. Huge thanks!

I tried this with my 1988 GMC Sierra but still no luck. Any suggestions?
