Defective key
 I have a 2006 330xi with 24,000 miles. Paid about $400 for Comfort Access. Engine should start with push button with key in my pocket.  Key stopped working. Clearly defective. Wont work with key in dashboard slot or with new battery. Dealer wants new key for $480. No wear and tear involved. Customer relations wont replace defective key at no charge. This is clearly technology gone mad.
