Keyless Go is convenient – but dangerous. Millions of vehicles in Germany are exposed daily to the risk of so-called "relay attacks" without their owners realizing it.
What is Keyless Go – and why is it a security risk?
Keyless Go allows you to open and start your car without taking the key out of your pocket. The vehicle continuously sends a radio signal – as soon as the key is nearby, the door opens automatically. This is precisely where the problem lies: the radio signal can be extended.
How the relay attack works
Two perpetrators work together: perpetrator 1 stands close to your house or office – where your key is located. Perpetrator 2 stands next to your car. Both use relay devices that forward the radio signal over distances of up to 300 meters. The car "thinks" the key is right next to it – and opens. The process takes only a few seconds. No force, no forced entry, no alarm.
Which vehicles are affected?
Almost all modern vehicles with Keyless Go – BMW, Mercedes, Audi, VW, Toyota, Ford, Renault, Tesla. According to ADAC, over 600 vehicle models have been successfully opened via relay attack.
Why are conventional security systems not sufficient?
Immobilizer, alarm, and GPS tracker do not protect: the immobilizer is bypassed, the alarm does not sound, the GPS tracker only helps after the theft – too late.
The most effective protective measures
- RFID-shielding protective pouch for the key – completely blocks the radio signal.
- Mechanical security – steering wheel or pedal lock increases the effort for thieves.
- Intelligent vehicle security – directly intervenes in the vehicle electronics.
