Citroen Grand C4 MK2 - How to identify key model (46 / 4A)

[lgiovanni]

Hello everybody!

I'm trying to program a spare key to my Citroen Grand C4 2018 as I just one unit of it.

Yesterday I saw that there are 2 diferent CHIP models (46 and 4A).

My question is: How can I identify the model of my car's key? Is there something in the key (label or different chip model) that allows me to see if my key is an 46 or 4A?

Tks!

Is this a push button start key or a regular blade type ignition?
I would imagine on a 2018 it will be a 4A system anyway.

Is it the one with a push button start.

I saw that the same key has the 2 chip options.
