I have BMW X5 2013. Somebody broke the driver key door lock yesterday night. In the morning I found the doors open. Now, the car does not respond to keys. There is no door response as well as the start does nothing when key is put in. I can switch on the indoor and main lights. The dashboard shows Power break light only for few seconds when I press the brake peddle. There are no other lights on dashboard. The Glove box apartment as well as boot door does not operate. There is a bing sound when I press the glove box button but no response. I am wondering what may have happened here ? Is it the keys [But I use one key and other is reserved and wonder how both are dead in one go] or is it the battery or something else ?
