Hi guys. I bought used Mercedes benz C class. Problem was with start a car. I use a key and unlock car. Put key at position 1 lights in instrumental cluster is ready but if i want to start up turn key in position 2 to start engine, but nothing happend. Pull key out and put in back, do a same thing engine start normaly. After drive once i tested with key 10 times and every time engine start normaly. After 30 min car stay at parking and try to turn on engine same problem. I try change a battery at key but same problem. Did anybody have same issue with start engine? Thx
