A method for operating an electronic device (35), in particular a mobile electronic device, wherein the electronic device (35) has a normal operation mode (NOM) allowing full functions of the electronic device (35), and a restricted operation mode (ROM) allowing only a part or none of the full functions of the electronic device (35), is characterized in that in the normal operation mode (NOM), the electronic device (35) expects to receive a next one-time upkeep code (NUC) within a specified upkeep time interval UTI after having received a previous one-time upkeep code,and that in case an expected next one-time upkeep code (NUC) is missing or incorrect, the electronic device (35) switches into the restricted operation mode (ROM).The inventive method improves the security of electronic devices.
