A hello to everyone, it is your swarm knowledge asked, because I am finished with my Latin. The following problem. From now on I could not open my smart by infrared key any more, he was dead. I thought. ADAC put it Smatri in the garden where it stands for 4 weeks. ADAC has read out: error code B111. He tried a lot without success. Auto key service came, has key coded. New batteries were inserted. NOTHING! Then an idea ?? Maybe it is the infrared receiver, ordered, inserted! NOTHING! (I opened the car at the rear flap) I can lock it with, the central locking button on the dashboard, key position 1, press, then 0, then and quickly out, o.s.a. fuses were checked (31+11) ! That’s it. Hope you can help me!! L. G. from Berlin, Sarah (battery from the car hung on the charger, so is full)
