97 service manual says to:
1 find data kink connector under steering column.
2 turn ignition on
3 ground pin 1 upper left most pin this is the programming line.
the door locks will lock then unlock.
4 press any key on the transmitter, locks will cycle to confirm
if you have a second transmitter press any button, wait for lock to cycle.
5 remove ground from pin 1
6 Done, test it out
By the way replacement transmitter battery is a CR 2016 Radio Shack has them.

I wonder if this would work with newer models.. i have a 02 SE. and the dealer didnt give me the keyless entry remote. was thinking about purchasing on online. anybody know if this method works on newer models? thanx

i know there is a easy way to program ADDITIONAL remotes.. its just that INITIAL programming that i need help with.

thanx
