The EWS control unit can manage up to. 10 keys paired with the control unit, which means that a maximum of. 6 spare keys are available. The control unit can identify individual keys, allowing keys to be blocked and released individually. If all 10 keys are lost, the EWS control unit must be replaced.
Any new key ordered is always released for the car, however central locking will not be possible remotely. The remote control keys must then be initialised. See function "Initialise remote control keys".
