Great thread.

I had this problem last week and the mechanic said I needed a new key (+$200). When I asked if it was covered under the warranty, he said 'come back when it's quiet and talk to your account rep'. At first he said new key, (note: do not revert to jerk mode) I said gee can you try to reprogram it or something? Just like a previous writer stated, he jumped in the X5, grabbed the steering wheel in a hug (so I couldn't see??). Then jumped out said it works now, have a nice day and walked away.

Thanks for the code, my brother has the same problem with his 2005 330xi - we'll try it next week.
