perhaps no fix coming
If the vendor no longer develops the software, seems likely the fix would be to upgrade the system, I find it unlikely most hotels would be willing to spend the $$ to upgrade so many systems for such a vulnerability, unless it starting being widely exploited.
The article is not clear but I think the good news may be that the vulnerability only affects systems that use NFC-like technology to authenticate the lock and not systems that use mag stripes(which I've read have their own issues).
In my hotel traveling experience in recent years maybe I can count on one hand the number of hotels I've stayed at that wireless key cards, one hotel in particular I stay at regularly upgraded to wireless key cards, their previous key card system looked as if it was at least 15-20 years old(had never seen a lock design like it at any other hotel I stayed at anyway).
