PATS transceiver / ignition immobilizer antenna ring

Hello, I am having trouble finding the PATS transceiver / ignition immobilizer antenna ring for a 2004 Jaguar XJ8.

VIN: SAJWA71C34SG27167

I attached photos of the part I need.

Thanks for any help.

Sorry I misspoke when I called security transceiver the MODULE.
It is the Key Transponder Transceiver.
The transceiver ring is the 'antenna' for the KTM. (part number C2C12637)
