Earlier quoted context omitted.

Still sounds pretty mysterious to me. This kind of event is rare, and the source of the interference is (currently) a mystery. I’d love to pop by with a HackRF and directional antenna if I lived anywhere near-by!

It's not that uncommon actually. Even at my car dealership this is a common problem. A couple hundred cars with the same keyless entry system parked in the same lot. All those cars are actively scanning for their key fob, which causes all sorts of RF collisions. I've gotten used to having to use my physical key when picking up my car at the dealership.

I guess that's the opposite failure case from 30 years ago, where there was a decent chance that your physical key would unlock another car of the same make/model.
