This TSB applies to 2010 Volvo S80, V70 and XC70 vehicles. One or both keys are not accepted by the vehicle, leading to a no-start condition.

DTC B10D794 may also be set, which indicates that the SCU (start control unit) is not able to read the transponder inside the key within the pre-defined time. If the vehicle is within the chassis range listed here, the symptom is most likely due to electro-magnetic interference caused by the chrome plated ignition lock bezel and not the SCU itself.

A new SCU bezel with a non-metallic coating has been introduced into production. The panel is available under P/N 9123403.

Remove the SCU to access the three bezel plate screws. Replace the ignition lock bezel and reinstall the SCU.
