For 3/4 of the year or so I’d prefer to not even have an actual key fob. In prior cars (Subaru BRZ) you could use a key fob which resembled a credit card. It wasn’t from Subaru but it was cross compatible with Lexus. Looking at KIA they have part number SY5KHCFGE00 which is similar. Details on usage are sparse. Any thoughts before experimenting with $100 and change?
