Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Replacing Transmitters (With SPS)
- This procedure will unlearn all previously learned transmitters. This includes accessory keypads. All transmitters that are to be programmed must be with the vehicle.
- A minimum of two transmitters must be learned during this procedure. The vehicle will not exit the learn mode until at least a second transmitter is learned.
- This procedure may be used with or without existing learned transmitters being present.
- This procedure will take more than 15 minutes to complete.
- A total of eight transmitters can be learned to a single vehicle.
- This procedure will only learn the vehicle transmitter information. This procedure will not learn any immobilizer information between the body control module (BCM) and engine control module (ECM).
- If the battery voltage is low, charge the battery before continuing with the procedure.
- Connect a scan tool to the vehicle and access SPS.
- Ensure that all power consuming devices are turned OFF on the vehicle.
- Select the SPS application and follow the on-screen instructions.
- Select Reprogram ECU.
- Select IMMO Immobilizer Learn - Setup.
- Select the Program Transponder or Remote Key (Delete) function.
At multiple times during the learn procedure, SPS will instruct you to turn the ignition to the run position. Make sure the vehicle is actually in the run mode before continuing on the SPS terminal. If the ignition is not in the run mode, the learn procedure will fail. To verify the vehicle is in Run mode, verify the green LED is illuminated on the ignition mode switch.
