How to program keyless remote for 2003 Alero

I recently purchased a 2003 Alero and found a pair of remotes on Ebay. Could you please tell me how to program these remotes?

Much thanks, Jeff

The Grand Am procedure is similar so checkout link below.

Try the one for the 2000 model. If that doesn't work then you'll probably have to take it to a dealer because a scanner is required. I had one programmed at the dealer and it cost around $37.00.

Thanks for the link, but as you suspected this does not work for my 2003 Alero. Looks like I'll be visiting the dealer...
