# Intermittent Operation and/or Difficulty Programming RKE Transmitter

Subject: | Intermittent Operation and/or Difficulty Programming Remote Keyless Entry (RKE) Transmitter -- Verify RKE Transmitter Part Number and Reprogram RKE Transmitter Using Updated Process

Models: | 2000 Saturn S-Series vehicles equipped with RKE -- RPO AU0

### Condition:

Some customers and technicians may experience intermittent remote keyless entry (RKE) transmitter operation while inside the vehicle. Technicians may also experience difficulty in programming RKE transmitters.

### Cause:

Intermittent RKE transmitter operation and/or difficulty programming may be caused by the RKE transmitter being too close to the body control module (BCM) during the reprogramming attempt. If the RKE transmitter is too close to the BCM, the RKE transmitter may overdrive the RKE receiver located in the BCM. This can result in an unsuccessful programming attempt and no RKE operation.

No operation of RKE transmitter may also be caused by trying to program an incorrect P/N RKE transmitter into the vehicle.

### Correction:

Ensure that the RKE transmitter is at least 1.2 meters (4 feet) from the BCM during operation or a programming attempt. Refer to the procedure in this bulletin to verify proper RKE transmitter programming and operation.

### Procedure:

Important:

• | 2000 model year S-Series RKE transmitters will only operate when programmed to a 2000 model year S-Series vehicle. 1999 and earlier model year S-Series RKE transmitters will only operate when programmed to a 1999 and earlier model year S-Series vehicle.

• | Although the RKE transmitter P/N has a 99 after it, this number does not indicate any model year usage information. The 99 indicates the range of P/Ns from 1263074 to 16263099. On 200 model year S-Series vehicles, Saturn uses the first P/N in that range.

1. Inspect the P/N on the back of the RKE transmitter intended to be programmed into the BCM.

• | If the P/N is 16263074-99, The RKE is for a 2000 model year S-Series vehicle.

• | If the P/N is any number other than 16263074-99, the RKE transmitter is not for a 200 model year S-Series vehicle. Obtain the correct P/N RKE transmitter and program it to match the vehicle.

Important: During RKE transmitter programming, ensure that the RKE transmitter is kept at least 1.2 meters (4 feet) from the BCM. Refer to the above illustration for BCM location.

Use the Tech 2 to program the RKE transmitter into the BCM. Refer to Program Key FOBs in the 2000 Body Special Functions section of the Tech 2 Users Guide.
2. Perform the RKE System Check to ensure proper operation. Refer to Remote Keyless Entry (RKE) System Check in the Locks and Security section of the 2000 S-Series Body/Electrical Volume II Service Manual.
