Question Protecting Keyless System from Hackers

Has anyone come up with a solution to protecting keyless entry key from possible hacking while it is in a pocket or handbag? I have tried putting them in Faraday bags but I and other users have found these bags stop working after several months use for no apparent reason. At the moment I have taken to wrapping the keys in silver cooking foil but this is a bit crude. Any other suggestions? Or has anyone found a Faraday bay that actually works long term. My XC40 is late 2019 which means it does not have the new key that blocks signals after being dormant for a period of time, eg overnight in a house. (This problem is not exclusive to XC40 but all new models with keyless entry.)

Try a Faraday box instead of the pouch.

The pouches for me would last 6 months. The box I now have carries on long term. Obvs not something to carry out and about though.

Surely it isn't beyond the wit of manufacturers' software teams to enable keyless entry to be switched off and an update for it to apply to older cars.

I'm well aware of the problems around keyless entry, I've got it on my car. However I thought it was a two handed operation with one person scanning for the key, typically within a house, picking it up and re-transmitting signal to a second person standing by the car. Reasonably close proximity of source key to car would therefore be necessary. Has technology moved on?

Default More to the point

Has anybody any authoritative data about the number of Volvos which are stolen by cloning keys carried in your pocket/handbag/briefcase? Id have thought it was a highly unlikely event.

Cloning keys kept on a hall table within feet of a car parked on the drive has happened, weve seen security camera recordings of it, but of Volvos?

Keeping your keys in a metal box away from the perimeter walls of your home ought to be sufficient to prevent the risk of theft by that means.
