Sicherheitslücke: ADAC warnt: Diese Keyless-Fahrzeuge sind leicht zu knacken
Für Diebe ein Kinderspiel: Es bedarf oft nur eines Funkverstärkers, um ein Keyless-Fahrzeug unauffällig zu stehlen. Eine sichere Technologie ist auf dem Markt - aber viele Hersteller nutzen sie nicht.
The ADAC, German automobile club, has warned that keyless vehicles are easy to break into due to a security vulnerability. Over the past decade, the ADAC has examined over 850 keyless cars, revealing known safety flaws. Despite this, nearly half of the vehicles can still be opened with an extended radio signal, and about one-third can have their engines started.
The thieves exploit this by stretching the signals between the car and the key using a radio repeater, allowing them to open the vehicle from hundreds of meters away, even through walls or doors.
The ADAC recommends a solution called Ultra Wide Band (UWB) technology, which is currently considered safe for keyless vehicles. However, many manufacturers have not yet adopted this secure technology. The ADAC's investigations found that keyless systems in vehicles made by brands such as Aiways, Alfa Romeo, Alpine, BYD, Chevrolet, DS Automobiles, Fiat, Honda, Infiniti, Isuzu, Jeep, KGM/SsangYong, Lynk & Co, MG, and Opel were not adequately protected.
Similar issues were found in models from Dacia, Ford, Hyundai, Kia, Lexus, Mazda, Nissan, Peugeot, Polestar, Porsche, Renault, Seat, Toyota, and Volvo, with only around 20% of tested models being secure.
The ADAC warns that a movement sensor in keyless systems can also pose a security risk. If the sensor is not moved for a certain period, the radio signal turns off, allowing the vehicle to be stolen during this time. The ADAC advises car owners to inquire about UWB technology when purchasing a keyless vehicle and to disable the convenience feature if it's not available.
If a vehicle already has keyless entry, the ADAC recommends asking the manufacturer if temporary disabling of the convenience access is possible to minimize the risk of theft. Additional tips include not leaving the key near doors, storing it in an aluminum case or special shielding boxes, or wrapping it in aluminum foil. In any case, owners should test if the measures are effective in preventing the key from opening the vehicle.
