Programming Additional Keys: Notes
The Adding Keys procedure does not erase any transmitters or keys prior to programming. The procedure will simply program the transmitter or key into the next available slot. The Adding Keys procedure should be used when adding an additional transmitter or key to the vehicle.
Using the Replacing Keys procedures will first erase all the known transmitters and keys from the vehicle. Any existing transmitters or keys and any new transmitters or keys will then be programmed. This procedure is typically used any time a transmitter or key is required to be unlearned or erased from a vehicle. If a new transmitter or key is being learned to a vehicle to replace a damaged, inoperative, or stolen transmitter or key, the Replacing Keys procedure is often used. This ensures that the old transmitter or key cannot be used to access or start the vehicle after programming. Refer to Replacing Keys .
If the key is unintentionally rotated while the vehicle is running, the ignition could be moved out of the RUN position. This could be caused by heavy items hanging from the key ring, or by large or long items attached to the key ring that could be contacted by the driver or steering wheel. If the ignition moves out of the RUN position, the engine will shut off, braking and steering power assist may be impacted, and airbags may not deploy. To reduce the risk of unintentional rotation of the ignition key, do not change the way the ignition key and Remote Keyless Entry (RKE) transmitter, if equipped, are connected to the provided key rings. Regardless of how the keys and key rings were configured when the customer brought the vehicle in for service, always restore the keys and key rings to the recommended configuration of the small ring on the key and the larger ring on the smaller ring. Advise the customer to follow this recommendation.
The ignition key and key rings, and RKE transmitter, if equipped, are designed to work together as a system to reduce the risk of unintentionally moving the key out of the RUN position. The ignition key has a small hole to allow attachment of the provided key ring. It is important that any replacement ignition keys have a small hole.
The combination and size of the rings that came with the keys were specifically selected for the vehicle. The rings are connected to the key like two links of a chain to reduce the risk of unintentionally moving the key out of the RUN position. Do not add any additional items to the ring attached to the ignition key. Attach additional items only to the second ring, and limit added items to a few essential keys or small, light items no larger than an RKE transmitter.
