I'm going to buy a Volvo car that has a keyless entry. These "keys" only send a signal that can be received when you are up close to the car. Do I understand correctly that the devices that car thieves use can nonetheless pick up the signal at some distance? I understand that there are Faraday boxes that one can get that block the signal or you can probably reprogramme the car so that they don't work, but this obviously defeats the benefit.

Yes, there are significant issues with car thieves using signal boosters and other such devices to increase the distance at which your key communicates with your car, allowing them to open and start it. There are a couple of solutions — one, keep your key in a ‘Faraday Cage’ when it’s not in use. This stops the signal from getting through. A Faraday Cage is a simple metal structure that blocks the signal, and it’s now possible to get key covers that incorporate one into the material. Secondly, turn off the keyless entry function — this usually means a visit to the dealer, as it’s not a function that often appears in the main infotainment menu. Finally, use a traditional anti-theft device such as a steering wheel lock, or a sturdy driveway post, to prevent your car being driven away.
