Help. Smart does not answer.

Hello, just wanted to start my smart has opened completely normally and wanted to turn it on. it does not do anything. neither a cracking anywhere or a noise from the starter … nothing at all. it lights up all the lamps in the tapo and the light from the switch of the rear window heater and does not go out either. moreover the smart permanently flashes to the right and it cannot be switched off. wireless remote control, windscreen wiper etc. what can it be? have tried to bridge the smart but also there does nothing. it is a gasoline with 50 ps fortwo. without climate and bj. 2001. thanks already for your quick help mfg
