Keyless entry fob

I have two remotes that belonged to my 1999 Jimmy that I no longer have. They have never been used and are like new. I have a friend with a 2004 Blazer that wants to buy them but I'm not sure they will work. They look the same but have different numbers on them. Will they work with his Blazer?

Doubtful. You have to go by numbers. If he is a friend, offer to try them. If they work, sell them. If not, list them on ebay.

Thanks for the reply. I'll give it a try.

Just remember once you start to attempt to program. Any keyfobs in memory will be erased.
