I think that this kind of tech is just fundamentally insecure. I can't think of a way to secure it, at least not against gaining entry to the vehicle. And making it secure against driving away (by requiring it to continue to respond to changing cryptographic pings as you drive) opens the door to people being able to use jammers to disable your vehicle remotely. Maybe if they have a special Faraday cage place that you put your fob into, but at that point why not just use a key? Or just require a button press like the key fobs have for decades.
Oh and depending on the latency allowances for responding to pings, it might just be possible to leave a device in the vicinity of the key and relay it over the internet, so even that just increases the difficulty of defeating it a bit.
Same thing also applies to wireless keycards for secure entry, though I think the range for those is generally lower, so it would be more difficult to pull off.
They have "pin to drive" so you can't drive even if you've gained access to the vehicle, without entering the pin-code first.
