Despite modern locking systems on vehicles some criminals do manage to overcome them by using devices bought legally and relatively cheaply on the internet. All of which work by affecting the radio frequency imitated by the key fob / device, enabling vehicles to be stolen despite owners having possession of the key(s).
Please see below advice on how to try to prevent these:
Consider using steering locks as a visible deterrent to thieves – someone who is so obviously conscious of security is less likely to leave valuables in a vehicle.
Keep your key device in a Faraday pouch, which has a lining that prevents the items inside from receiving or transmitting radio frequency signals.
Avoid parking in dark, secluded areas, choose locations that are well lit and over looked by houses, passers-by and covered by CCTV if possible.
Do not store keys near windows or doors.
