Bmw x3 cruise control locked on

SOURCE: lost keys require new locks for BMW X3

replacing the complete lock set with the EWS control unit can be expensive as the control unit will also need to be programed and/or encoded, however if the lost keys cannot be found and you are sure they cannot be used to steel you car you can just order replacement keys from your local bmw dealer. hope this is of some help. You will also nead to disable the lost keys if you order replacements rather than a complete set.
