Bought 1999 e320 drove it home got up next morning key won't not start car or work at all
Do you have a second key to try? Also does it work for unlocking the car?
No just one key yes it unlock door but not ignition
I know it has been a while but did you ever resolve this problem?
On the fob lock and unlock it then within 30 seconds put the key in the lock and lock and unlock it and thats worked for me
