The RKE programming connector (BLK/WHT wire) is grounded (CKT 1455).
The RCDLR is replaced.
A keyless remote transmitter is replaced.
A second (up to a total of 4) keyless remote transmitter is added.

Programming Procedure :

Important:
If the vehicle has more than one keyless entry transmitter, ensure that all of the keyless entry transmitters are programmed during the same programming sequence. Any keyless entry transmitters that are not programmed will not work correctly.

Open the rear compartment lid.
Pull aside the right side compartment trim in order to gain access. Refer to Compartment Side Trim Replacement - RH Rear in Body Rear End.
Use a jumper wire with alligator clips in order to ground the RKE programming connector. The door locks will lock and unlock. This action indicates that the RCDLR has entered the keyless entry transmitter programming mode.
While the programming connector is still grounded, program each of the keyless entry transmitters, one at a time. Press and hold the LOCK and UNLOCK buttons simultaneously on the first keyless entry transmitter. Hold the buttons for 10 seconds. The door locks will lock and unlock. This action indicates that the keyless entry transmitter has been programmed.
Repeat Step 4 for the remaining keyless entry transmitters. You may program as many as 4 keyless entry transmitters.
Remove the jumper wire from the RKE programming connector terminal.
Verify that the keyless entry transmitters operate correctly.
Install the right side rear compartment trim. Refer to Compartment Side Trim Replacement - RH Rear in Body Rear End.
Close the rear compartment lid.

SUPPLEMENTARY NOTES:

1) Despite the manuals vagueness about the location of the RKE programming connector, it is fairly easy to find. It is small black plug on the end of a black and white wire, taped to the main wiring harness with electrical tape, about half way between the base of the antenna and the rear of the car.

2) You should ensure that you have a good ground connection ... initially I didn't have a good ground and couldn't figure out why the RCDLR didn't lock and unlock the doors (i.e. go into programming mode).

Will this work for a '96 Lumina sedan?
