Lost Key Fob - cheapest solution?

A friend of mine lost her comfort access keyfob to her 428i 'vert, but still has the metal blade key part. What's the cheapest place to get a replacement fob? Can it be programmed to the car like the old e series keys with a combination of start button and unlock pushes, or does it need a trip to the dealer? I tried searching but didn't see anything definitive. It looks like bimmernav doesn't offer f series keys.

Any help would be appreciated. Thanks

Comfort access definitely requires a trip to the dealer. Even my local mechanic was not able to program my spare key fob, and they have a certified BMW machine to do it.

The dealer will have to order it. They're about $300

Thanks for the video. My understanding is that method does not work for comfort access. In order to enable comfort access, the dealer has to remove the old key from the system and add the new one (only two comfort access keys can be paired to a car at a time so says the interwebs...)

What about the used key fobs on ebay that look to be comfort access. Can those be reprogrammed?

I've got three functioning keys for my 335i MSport with comfort access. I purchased the car used and it only came with one key. I paid over $400 to get a new key with programming. Then about three months later, the dealer I purchased the car from "found" the second key for the car and sent it to me.
