How to program 99 Malibu key fob?

How can I program another key fob for keyless entry on my '99 Malibu LS?

1. Turn the ignition off.
2. Ground the receiver program terminal. Jump the two terminals located in the programing ground connector. (What this means in simple terms is locate the wires that run on the right side of the trunk. There is two black wires that has a plug on the end with two prongs. It is in between the antenna and tail lights.)
3. Within 2 seconds of connecting the prongs the door locks will lock. The unlock and the rear compartment lid release will produce a cycle, causing the horn to chirp. This indicates that the module is ready for reprogramming.
4. Press and hold the lock and unlock buttons at the same time until the doors lock and unlock. The rear compartment lid will release and the horn sounds to indicate that the transmitter has successfully been reprogrammed. (Hold buttons down for approximately 12 seconds)
5. Repeat the previous step for the remaining transmitters.
6. Remove the jumper at the program connector.
7. Verify the proper operation of each transmitter.

Thanks for the very clear instructions. If you were any closer to Alberta Canada, I'd buy a fob from your website. Cheers.

We do ship to Canada if you're still looking for a fob.

Look at instruction #2, the part in brackets, where it says it's on the right side. Up there, above the wheel well, behind the trim panel.

Is this procedure the same for a 2001 Malibu?
Because I looked for the wires between the antenna and the tail lights, and the only wires there were for the antenna and the tail lights.
Any other places it could be?
