Remote Keyless Instructions for 98 Buick Regal

I lost one of my keyless remotes and will be buying a new one and want to know where I can get the programming instructions.
Is it difficult to program these remotes?
Can I possibly break my car by doing this programming?
I am a rather clueless mechanical person but cannot see paying the dealer $50 to do the programming.
Thanks in advance.

check out this site for a remote that supposedly will come with programming instructions and toll free help. http://www.keylessride.com/order/default.asp?make=Buick&remoteyear=1998
