Make sure that the battery terminals are clean and tight. Low voltage will not activate the Drive Authorization System (DAS) that allows the key to turn the ignition switch. The next step will be to check the Mercedes EIS / EZS Immobiliser Key Module, it may have a problem and needs to be replaced.
