My Mk7 3 door is keyless.I don't have a faraday pouch yet so i just put it in the microwave.It works just as well as a pouch.
I think performance cars like the A45 AMG,Audi RS3,etc are a bit of a liability with the keyless option.Been looking at some ads recently, and what was once sold as a plus point is now a negative in todays market.
Good that VW have moved forward with security on this issue.I think the latest cars (like the latest Merc A class) have evolved again to close the gap on the security.
