Wow, that's an interesting hack. I can't think of any workarounds either.

EDIT: As pointed out in a comment elsewhere in this thread:

> The simplest defeat is to require the key ping round trip to complete in N microseconds, where N is sufficiently low. Researchers have demostrated that this is a practical solution.

Don't Have Keyless Entry.

It's getting to the point where I don't think I'll ever buy a car made after the early 2010s.

On my Toyota Prius, it's possible to turn off the keyless entry system in the car's settings IIRC. You'd then have to use the removable key in the fob to open the driver's door.

people have been stealing cars since cars were invented; avoiding keyless entry doesn't exactly immunize you.

Remember, light moves at one foot per nanosecond. You need to perform a cryptographically-safe ping with timing drift of less than 15 nanoseconds.

I think this is doable: https://en.wikipedia.org/wiki/Distance-bounding_protocol

Doable doesn't mean easy though. It's far harder than dealing with microseconds. And how much do analog prover components cost?
