Hey everyone

I have a 1997 k1500 truck and want to program a key fob from a blazer to it. I've gotten as far as getting the truck into programming mode where you connect pin 4 and 8 on the data link port and the doors lock and then unlock. then i would hold the lock and unlock buttons on the key fob but nothing would ever happen. Can you program a blazer key fob to my truck, is so, how?

 

First, make sure the numbers on the back of the remotes match and remote Battery is in good cond,
Then I've had good luck with programyourremote.com
Good luck, Fred
