2008 BMW 528xi Q&A

2008 BMW 528xi Question: Key won't go into ignition and start engine.

My car was detailed today at a car wash and when I went to pick it up, the key would not go into ignition slot. I got a warning light with a slash through the key. After several tries, the car started, but the key wouldn't stay in the ignition and the warning signal stayed illuminated showing a slash through a key. What could be the problem? -
Answer 1
Not sure, but it may be either with the key or with the lock cylinder. Have you checked with the dealer yet? -

The next morning, the key worked and since then I've had no problems. Maybe some dampness got into the cylinder and it dried out. It's a mystery, but all is well. Thanks for responding. -
