What is the deal with replacement "diamond" keys? I placed an order for one at the dealer in November and they still show out of stock with no estimated delivery date.


I only have a single key that came with the vehicle and the remote doesn't work. I am concerned of losing the key, and/or the lock cylinder going bad and being stuck.


From what I've heard the eBay replacements all need programming and the BMW dealers won't touch them. Are there any alternatives? This seems like laughably bad service for BMW to force owners to source keys from them (at ridiculous prices, almost $300) and then not even have them available.
