The point is how much do you need?
Numbers of research showed that some models are more vulnerable than others. Some carmakers produce models with an embedded system that is resilient to keyless crime. Thatcham’s research revealed insecure brands where they take13 different makers and examine them. The study showed that automakers are doing their best, but some of them should do more. Richard Billyeald, Chief Technical Officer says: “The number of carmakers now offering Relay Attack counter-measures with new vehicles is steadily increasing and should be applauded. However, all new cars with keyless systems ought to have a solution to this long-standing vulnerability in place.” Some models passed the test without difficulties. Those models are the followings:
What do those automakers do differently? Some manufacturers use motion sensor technology, as it seems it works for the owner’s advantage in terms of better protection. For example, what car? tested keyless models and they conclude that motion sensor technology really works and makes some models less vulnerable. Those were: Audi TT RS Roadster BMW X3 xDrive20i M Sport (2018 model), Ford Fiesta 1.0 Ecoboost 140 ST-Line X Mercedes A-Class A220 AMG Line.

They have a wireless transmitter, one of them stands close to the owner’s front door or windows and tries to catch the signal coming from the fob and relay it to the second thief who stands close to the target. As a result, the vehicle is tricked into thinking that the fob is nearby.
Jamming – Criminals use a special electronic tool, which is available online. owners believe that they lock their automobile however those transmitters interfere and prevent it from locking.
Programming – Another problem with electronically controlled automobiles is that hackers can mess with the onboard diagnostic port, plug the device and program the blank key.

However, some research indicates that the pouch is not as reliable as you believe. The thing is you should test them before you use them and it can be tiresome. Thatcham’s chief technical officer Richard Billyeald says: We have tested a few of the pouches and the ones we’ve assessed have worked, but we can’t guarantee they all will. Some pouches have two pockets, for example, only one of which will block signals, while there are so many on the market it’s simply not possible for us to test them all.”
