Modern fobs should be designed to prevent replay attacks (there should be something specific in the request that alters the response), so it shouldn’t be possible to record a response and then use it later.
Comment on What security purpose a Faraday bag has when it contain a vehicle keyfob
ReginaPhalange@lemmy.world 19 hours ago… Which means that if the hacker is near you when you park - there is a time period where the fob isn’t masked by the bag, because it is coming out of the ignition, and voulaa - you can record the key’s pong of the car’s ping, retransmit, and get in. Correct?

That is a possibility if you aren’t normally keeping it in the bag unless being needed in the moment.
It is far more common for the attempted theft to occur late at night because thieves avoid greater risk.
