Hi together, yesterday evening in a public underground garage with low ceilings suddenly the radio lock no longer worked. Also the try with the 2nd key, which we had with us by chance, did not bring anything, the part was dead. So back home and bring other car before the immobilizer turns on…but see there…at home and since then no problems, it works like it should… What could that have been? Can it be that in the underground garage something disturbs the radio station or receiver…???
