How to determine key modulation. ASK or FSK

[Dim]

Hello
Can anybody help me to get modulation by VIN?
My car is Citroen C3 Picasso late 2009
Is there any way to detect FSK or ASK without having original key? by VIN or whatever

Thanks

My notes suggest this is FSK

I also think its fsk but on some web pages people say that Citroen use fsk in cars starting from 2010 manufacturing year
anyway thanks for your message. it make me to be more sure in fsk
