A remote entry

From the factory service manual:
RKE Programming:
1. Using a functional key fob transmitter, unlock the vehicle & disarm the Vehicle Theft Security System.
2. Insert ignition key into the ignition switch.
3. Turn the ignition switch to RUN position with- out starting engine.
4. Using a functional key fob transmitter, press & hold the UNLOCK button for a minimum 4 seconds (maximum 10 seconds).
5. While holding UNLOCK button, & before 10 seconds passes, press & release the PANIC button. A single chime will sound to verify that the Remote Keyless Entry (RKE ) module is set to receive the new Vehicle Access Code(s).
6. Within 30 seconds of the chime, press any button on each new key fob transmitter. After 30 seconds or when ignition switch is turned OFF , the RKE module will end the programming mode. A single chime will sound to verify that the RKE module will no longer receive additional Vehicle Access Code(s).
7. When Vehicle Access Code(s) programming is complete, turn Ignition Switch to the OFF position & verify RKE system operation using each key fob. NOTE: Only the primary (first two) key fob transmitters will operate the memory seat & mirror systems. If a primary key fob is being replaced, the memory seat & mirror module will require programming.


Remote Keyless Entry (RKE) Driver Memory Programming

Notes, The memory seat/mirror module interfaces with the RKE via a serial data link (single wire). The programming sequence to relate an RKE transmitter to the chosen seat, recliner & side view mirror positions consists of the following steps:

1. Adjust the seat, recliner & side view mirrors to the desired position.
2. Press momentarily & release memory switch S.
3. Press momentarily & release memory switch 1 or 2.
4. Press momentarily & release a LOCK button on an RKE transmitter.
5. To program the second driver is position, follow the previous sequence with a second transmitter.
To recall either of the programmed positions with an RKE transmitter, press momentarily & release an UNLOCK button on one of the programmed RKE transmitters. An unprogrammed RKE transmitter will have no effect on the system.
The RKE receiver uses the serial data link to notify the module of a request from a programmed transmitter, that an UNLOCK button has been pressed. This UNLOCK request (from a transmitter associated with either switch 1 or 2) will activate the Memory Seat/Mirror Module in the recall mode to the values that r stored in the module is memory.
Whenever the module receives a specific data stream from the RKE receiver that involves the programming of a new transmitter into the RKE receiver, the module will clear its nonvolatile memory seat & recliner values for both memory 1 & 2 & will default to a location consisting of seat track rearward, seat vertical risers down, & recliner forward in both memory 1 & 2. After this has occurred, the customer must reprogram their desired seat & mirror positions.
A recall is possible any time that the vehicle transmission is in PARK. This condition is monitored by the Body Control Module (BCM) .
A ground placed on the serial data link by the BCM whenever that the transmission is not in PARK, will inhibit a recall request from the door mounted memory switch 1 or 2 or the RKE receiver that was initiated by either of the validly programmed transmitters.
NOTE: The module will abort a recall if the transmission is moved out of the PARK position or if any seat, recliner or memory switch is pressed.
