Summary
TRANSMITTER, Integrated Key FOB Due to a global semiconductor shortage, service availability of this part is limited. To maintain production and service requirements, FOBIKs affected by the shortage will be available on an ?as required basis?. This FOBIK should only be ordered in the event the vehicle is inoperable, and there are no other FOBIKs available. It is requested the customer uses their spare FOBIK until supply is once again available. On some 2021 vehicles, they will be sold with only one FOBIK, and will have sales code ?GXZ?. For these vehicles a CSN (Customer Satisfaction Notification) will be released to replace the FOBIK once supply is available. A unique part number will be used for this campaign. For these vehicles, only order a replacement FOBIK in a vehicle down situation. Due to the global shortage, once service inventory of this part is depleted, there may not be any additional parts available for service for an extended period of time. This may cause customer dissatisfaction and extended vehicle down time. We appreciate everyone?s consideration and cooperation to only order this part in a vehicle down situation.
