The FCC number is the same on all all keys - it is the 315 mhz frequency used in the US.
That ebay remote is for a 996. Boxster keys start with 986. But it is a good deal for a 996 owner, or maybe you can get it to work on a Boxster.
Each remote has a unique 24 digit code on the paper tag. Without that code the remote is worthless.
