Could anyone with more knowledge confirm, but couldn't they just do what some car companies are doing and have a system by which you can just disable keyless entry when it's parked up at night?

If I'm at home and my car is parked up where the key could potentially be repeated then I just disable it by locking the car using the key and tapping on the door handle, which disables just tapping the door handle to unlock it again, and only the unlock button on the key works. As far as I understand it resolves this issue, unless I'm missing something?

This seems a lot more complicated and much worse than just using actually cryptographically secure keys to verify that it's the real key.

Or just not storing your key where it can be repeated 🤪 this attack is 100% mitigated by some distance or just fuckin' aluminum foil.

You would need to put your keys in a faraday cage.

Distance doesn't matter, as they can just use a bigger antenna or better amplifier. You find footage of people using large loops of wire to capture the signal from the keys
