Wonder what the "process" to solve this is if they don't even know the cause?

Cars not having physical locks on doors or for ignitions anymore is one, I assume.

#15It'll be someone using a 'jam, listen, and replay' device to unlock and start keyless cars so they can drive them to a port and steal them.

I now always take the engine management fuse out of the fusebox when parking my car so at least the car can't start when a thief pulls this... They tried anyway though!
Where do you live that a car gets stolen from your street every week?
I can share that from living in a Northern UK city, between 2 or 3 "notorious" streets there would be multiple car break-ins each week. The University's student Facebook page became a constant feed of people reporting cars with smashed windows.

#16There is nothing 'mysterious' about this, this is just how radios work. Neither does it have to be malicious. Most car key fobs work in the 433MHz range, if there is something in the area transmitting at said frequency, it will cause the relatively weak signals from keys fobs to be blocked. This it why we have electromechanical compatibility (EMC) certification for any electrical devices being sold. With the market b…
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!

#18Article from a few years ago about a neon sign switching-mode power supply that was causing interference on the 433MHz frequency (as well as others):

And “an inventor” who's make shift doorbell was causing problems on 355MHz:

Trouble with these devices is they rely on all applications just transmitting data very briefly. If someone doesn't it can block everything
