My 2012 X5 remote key has been acting up for about a week. When I go to open my door in the morning by pressing the button , the doors will not open. If if press on the door handles to open the door nothing happens either. I have to physically put the key in the door to open it. I also have to to put the remote into the slot on the dashboard for the car to start. This doesnt happen all the time so I'm not sure if it is the remote key or something else in the car, any suggestions?
