C-8 Question 2022 versus 2021

[Jimmy G.]

In the owners manual of a 2021 it gives very precise instructions to add a third Key Fob. It is missing in the 2022 Owners manual as far as I can see (says see dealer). Does anyone know if the programming instructions for a 2021 will work on a 2022 as I have a third FOB in transit.

It does look like the procedure for adding remotes changed for 2022..

• Adding Transmitters (With SPS)

• To prevent errors or immobilizer learn failure, the vehicle must be in Park (for automatic transmission) or Neutral with park brake applied (for manual transmission).
• 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 (Add) function.[COLOR=brown !important]Note:
  • 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 igniting 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.
  • For the transmitter pocket location refer to the Remote Keyless Entry (RKE) System Operation document in the owner manual.
  
  
• Follow the on-screen instructions.
• After programming all transmitters, Programming Complete, is displayed.
• Press and hold the ignition mode switch for 15 seconds.
• Press the lock and unlock button on each transmitter that was programmed. This will awaken each transmitter and allow passive and active keyless entry functions to be established.
• With a scan tool, clear any DTCs.
• Verify each transmitter that was programmed is operating properly. Operate each of the keyless entry functions using the buttons on the transmitter and then start the vehicle. When verifying operation, make sure that no other transmitters are near the vehicle.
