Key Activation

Keys that are lost or stolen may be deactivated or made to not operate the starter functions. The SERVICE FUNCTIONS of the DISplus or MoDic for EWS II contains a "Bar/Release Code" function that activates and deactivates keys of the EWS II. Any key may be "Barred" except the key in the ignition at the time of deactivation. The lost or stolen key can be identified by the identification of the remaining keys.

There is no limit to the number of times a key can be activated/deactivated.

Beginning MY 1997 E31 and E36 vehicles with manual transmissions were updated to include a clutch pedal position switch. The clutch switch signal is provided by a hall-effect sensor providing a high signal when the clutch is depressed.
