Looking for FCC ID

Dear Members,

I recently bought a Corolla Runx 2004 (CBA-NZE121) and it came with only one manual key. I am looking to buy a remote key from Aliexpress and find difficult to match the correct chip. One seller asked me to send the FCC ID which I have no idea how to find. Any clue? Any suggestions are appreciated. Below is the detail I only have about my car. Also, I can say it already has the central locking mechanism installed since all doors can be locked by the driver side door lock using the key.
