Thieves use relay devices to amplify the signal from the key fob in your home to a transmitter near your car, which essentially tricks your car into thinking the key is present. This allows them entry into the car, where they can use the start-stop button to start the car without the key. The key also doesn't need to be present within the car for it to continue running - so they can keep driving as long as the ignition isn't turned off at any point. As far as we're aware, any keyfob is vulnerable so if you're 3008 has keyless entry and start then it's a good idea to buy a signal blocking pouch for the keyfob. Or you can wrap it in tinfoil (or put it in a metal box). It's free but it's a bit weird to carry around a key wrapped in foil in our opinion.

We've tested this one, it's very cheap but we've had reports that it does fall apart after a while so buy whatever signal blocking/faraday bag is best: kit.honestjohn.co.uk/reviews/review-monojoy-keyles.../
