car remote

I have a 2001 olds alero that I purchased at an auction but nerver got any remotes with it. I am planning on buying some but was wondering if there is any way to program these without the $100 cost from my local dealer to do so?
Thanks in advance for all your help

almost all sellers on ebay offer free and simle programming instructions with their remotes

You need to bring it into your dealer, sorry. they need your vin and they need to program it.
