Keyless remote programming for "97 GCL

I bought a keyless remote for my "97 Jeep Grand Cherokee Ltd and need to know how to program it to work. I have the original remote #1. This one is the #2. Can anybody help me out, PLEASE!!!!

I am also having trouble finding programming for the keyless entry remote for a 2004 Jeep Grand Cherokee.

Ditto here for 99 Grand LTD. Bought off ebay for $10. I have lost my only key and remote that I was given (purchased used), so my jeep is on vacation, but my payments are not. Any ideas? I have ordered a blank Transponder key but heard to have it cut and programmed (has to be dealer ?) will run several hundered?!?!?!?!?!
