Major security flaws remain with remote keyless systems

Cars using remote keyless systems are still much more prone to theft than those with conventional key systems, reports the ADAC, Germany’s largest automobile club. In a test of over 180 models, only one, the 2018 Land Rover Discovery, has passed the organisation's security tests.

In the experiments, technicians used a self-built radio extension which, according to the ADAC, potential thieves can easily assemble from everyday electronic parts. This can extend the radio connection between key and car up to one kilometre, regardless of whether the original key is in the owner’s home or in a jacket pocket.

Using this kind of system, thieves can quickly open a car and drive away, since any immobiliser and most alarm systems are bypassed. After all, with keyless remote control systems, the driver in many cases no longer has to press any buttons to unlock the car.

Only a few models allow owners to deactivate the keyless system after purchase. According to an ADAC spokesman, this is certainly not in keeping with the original intention of such an invention, since no one would pay an extra charge for a system only to then deactivate it.

The club advises car owners to remain vigilant when storing their remote keys, and never keep them near windows and exterior doors. In the ADAC’s view, manufacturers have a duty to ensure consumer safety and should thus provide drivers with retrofits. — dpa
