Talking Re: Using car key fob as generic remote control

Ok, good to know - that's why I said "inferred" . What threw me off is the antenna coil in the datasheet for the PCF chip, connected to the "IN" pins on the left - apparently those receive something back from the car ? I thought those represented the NFC antenna for the immobilizer...or something.

Is the immobilizer the little coil here ? That's the board the fob for my Renault uses, by the way.
