For several years, the ADAC has been warning against car theft using radio extensions in keyless locking systems. So far, only a few cars offer convincing protection. Thieves continue to use key signal extenders to gain access to vehicles and start engines.
The automobile club has already used this trick on more than 500 tested cars since 2016, so far the attempt to overcome the security system has only been unsuccessful in 24 cases. These were all keyless systems with ultra-wide-band technology (UWB), which could not be manipulated with the devices used. With UWB, the system can detect whether a car key is actually in the immediate vicinity of the vehicle. A security technology used by some manufacturers as an alternative is a motion sensor integrated in the key, with the help of which the radio signal is automatically switched off if the key is not in use for a certain period of time move. The ADAC has documented this technology in 37 vehicles so far, which makes intercepting the radio signal less likely, but not impossible. Only owners of cars with a UWB solution can really feel safe, which Jaguar Land Rover has had in several series since 2018 as well as has been increasingly used by volume manufacturers of the VW Group since 2019. The first models with UWB are also available from BMW, Mercedes and Genesis. Here you will find the complete list of the vehicles tested! If you want to protect yourself from keyless theft without UWB protection, you should not store radio keys near doors and windows and also park the vehicle in a locked garage. Alternatively, the automobile club recommends looking at the operating instructions, because some keyless systems can be deactivated. This means that the keyless convenience is lost, but the vehicle can no longer be cracked by signal theft. (SPX)
