## NHTSA's summary

"Keyfob WL/WS/LB Key fobs unable to be programmed at dealers. Please check current stock and verify a Blue ""OK"" mark on part label. If not present send part back to Mopar under RMA 8925\-792 and replace with clean stock from Mopar. Some vehicles may exhibit DTC B1A0A\-00 that has set erroneously and with no associated owner complaints. It is not recommended to replace any parts for this concern, all service parts will perform the same. Engineering is aware of a software issue that may set this false DTC for FOB 3 Performance when there may not even be a FOB 3 programmed to the vehicle. A software update is expected to be released within the 1st quarter of 2025 to correct this concern."
