Hey guys new members check this out I have a 2007 x3 BMW that would not start, ok change the battery not it, BMW dealership you need a dme, cost $2200 no deal went to someone who's know BMW cars well, lots of test, car won't start still
Here is the deal, go home get the other key to your car, this is it, the keys are interfering with each other making the car think it's being with an shout down the starter. One key start the car but won't lock the door, if the key lock the door it won't start the car. Found don't have both keys in the same place. Come from droping them to much get a new key made at dealership, hope this helps. Check before buying dme. Thank Jlaw.
