These instructions showed up in one of the threads I have bookmarked from ClubGP. You can give them a shot:
Here's the procedure for programming the keyless entry transmitter:
1. Sit in driver's seat.
2. Remove ignition key from ignition
3. Close all doors
4. Press and Hold the Door's Lock switch to the Unlock position.
5. Insert and remove the ignition key twice (don't rotate the cylinder - leave in off)
6. Insert the ignition key a third time, leaving it in the cylinder
7. Release the Door's lock switch from the Unlock position
Three fast chimes will indicate the system is entering programming mode
8. On the keyless entry transmitter, press and hold both the Lock and Unlock buttons simultaneously.
Two fast chimes will be heard to confirm programming of the keyless entry.
You may have to hold both buttons for up to 12 seconds
9. Repeat step 8 for each transmitter.
10. Remove ignition key from cylinder.
I had the correct ones bookmarked at one time...but then the forums were redsigned and none of my links worked anymore
