Should a 1999 Blazer LS originally have a key-less remote system. When I bought this Blazer used, I only received the keys, and didn't realize that maybe there was a remote originally. If there was one, do I have to go to a Chevy dealer to get a spendy new one?

 

Have you tried to put the truck in learn mode?

 

I got a key fob from a salvage yard for $15. They are on ebay too.

 

places like Napa sell new aftermarket replacement remotes for some vehicles

 

Some came with keyless entry, some did not.

 

What is the easiest way to find out? Chevy dealership?? My 2003 did not come with a key "fob"

 

Sticker in glove box has rpo codes. keyless entry = AU0

 

Great! I have a "AUO" code in the box. If I can find a FOB at a salvage yard, how do I re-program it?

 

The FCC ID number needs to match on the key fob and the keyless module.

 

keyless module on your truck should be located behind the passenger or driver kick panel.. I think. Then search ebay for your year truck and match the numbers
