Happened to me as well, but randomly. If I press the unlock or lock function on the remote it then detects the key. And works fine for a month or so.
I mentioned this to my dealer and they changed the battery. Still happens randomly, but unless the dealer can recreate the problem at the shop they won't look into a solution.
Therefore... If your issue is always happening, or repeatable, please go to dealer and get them to resolve under warranty (assume you have). And then please tell me what they did to fix it

Bulletin LI80.61-P-049924 may be applicable – 204/207/212 at times not possible to start engine via KG at same time “Key not recognized” message appears. Normally, if a key is not correctly recognized during the first query of a Keyless-Go start process, the query is automatically repeated 1 more time. Due to a SW error in the Keyless-Go control unit, there is no engine start repeat function for certain keys – update control unit software.
