2006 Pontiac Grand Prix Programming Keyless Remote

I bought an 06 Grand Prix used. It did not come with a remote to open the doors or trunk as the owners manual stated. I spoke to the dealer where I bought the vehicle and he said he did not have the remote to the vehicle. If I buy one is it user programmable or will I need to take it to a dealer? What would be a reasonable charge for this? I read where a PGM fuse may have to be removed for user programming. If so where would this fuse be located?
