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

maybe they bring out the huge car sized faraday cage

[WJW]

If you build a structure out of supermarket trolleys around the car, would that be sufficient? I love the idea of a car size foldable Faraday cage btw.

Serious answer? Maybe. It would depend on the frequency the keyfob is using, and the spacing of the grid, and the metal they're made of.

There's a good chance a cage made out of shopping carts would block HF and below quite effectively. UHF and microwave will go straight through it though. Any holes need to be significantly smaller than the wavelength.

I would bet a small amount of money that the process is (1) put the fob very close to the car's receiver and try again, followed by (2) disassemble the fob and look for a mechanical key.

Portable faraday cage over the car and driver?

I wonder if a cone of tinfoil (handily available at Tesco) would work, shielding key and lock during unlock? Or are the receivers elsewhere in the car?
