To reprogram your keyless entry system for a new key fob:
1) Turn ignition to OFF.
2) Ground pin 1 of the Data Link Connector (black 16-pin connector under dash driver'* side). Pin 4 of this connector is a ground, so placing a jumper wire between pins 1 & 4 will accomplish this. Grounding pin 1 tells the system you are getting ready to reprogram it.
3) Close all the doors.
4) Turn the key to ACC, then back to OFF. The power locks will lock/unlock. The system is now ready to be programmed.
5) Press a button on your key fob.
6) If you have two key fobs, press a button on the second fob within 1 minute of pressing a button on the first one. Both must be programmed at the same time. If you only have one remote, press a button on it 2 more times to signal that you only have one.
7) The doors will lock/unlock to signal that the codes were received.
8 ) Remove the connection between pins 1 & 4.
I found that the power locks locked and unlocked immediately upon jumping pin 1 to pin 4. The system was ready to be programmed. steps 3 & 4 were unnecessary.
That'* more similar to what I remember for my '95 SE. Except, I didn't know about the multiple fobs until this minute.
I can remember doing fob A. Great it actually worked. Then i did fob B and that worked. Double great... But then fob A didn't work. So i redid fob A and then fob B didn't work.
Fortunately, my wife stepped in to stop me from further stupidity, and a road to insanity which would have lasted 9 yrs 'till tonight.
Steps 3 and 4 might be necessary in an SE, which doesn't have the key On/Off, lock/unlock as part of its normal programming.
