I have the following problem: KeylessGo sometimes didn’t work lately, with the second key already. First key doesn’t work with new battery, the second key doesn’t work anymore. Open with the mechanical key doesn’t work either. Keys can be turned, but the lock doesn’t matter. After many attempts, the car is now open and it started after several attempts. Starter went through quickly, so that the car battery probably isn’t the problem. Nevertheless, I first connected a charger. Since I need the car tomorrow morning, I don’t dare to close it again. Did it try with an open window, but there was no reaction again. Does anyone know what this can be? Especially irritated me that I couldn’t open the door with the mechanical key. Frustrated greetings Jürgen
