Yes, a keyless car can be stolen using techniques that exploit the technology's design. The primary method is a relay attack, where thieves use electronic devices to amplify the signal from your key fob, which is typically inside your house, and transmit it to your car parked outside. This tricks the car into thinking the key is present, allowing them to unlock and start it. Another method is a signal jamming device that blocks the lock signal from your fob, leaving the car unlocked without your knowledge.
The risk is real. In the UK, for instance, the Office for National Statistics reported that keyless car thefts accounted for a significant portion of vehicle-related crimes in recent years. Modern cars with keyless entry and start systems are often targeted.
Common Methods of Keyless Car Theft:
| Theft Method | How It Works | Vehicles Often Targeted |
|---|
| Relay Attack | Two devices are used: one amplifies the fob's signal, the other transmits it to the car. | Most keyless entry systems, especially luxury brands. |
| Signal Jamming | A device blocks the radio signal from your fob when you press the lock button. | Any vehicle with a keyless fob; common in parking lots. |
| Key Programming | Thieves gain entry (e.g., via a smashed window) and program a new key using the car's OBD-II port. | Older keyless systems with less secure programming protocols. |
To protect your vehicle, use a Faraday pouch or signal-blocking box to store your key fobs at home, as these block all radio signals. Also, consider a steering wheel lock or a GPS tracker as a physical and digital deterrent. Always manually check that your car is locked by pulling the door handle after using the fob.
