You know what: I own a Hyundai and I want a low-tech version of this.
My key fob got damaged. Hyundai quoted me $600 for a new key. That's half my wages for a fortnight. For a key. Used to be you could go and get a new key cut for $10.
So yeah, if there's a way to break into my own Hyundai for way less than $600, I want one.
