A growing number of high-tech vehicle thefts targets cars equipped with keyless entry and pushbutton start systems. Thieves are using antenna scanning devices often called “relay attack” tools to unlock doors and start engines without breaking windows, forcing locks, or possessing the physical key. These thefts can take less than a minute and often leave no visible evidence.
The method works by capturing the radio frequency signal emitted by a key fob. One device scans and amplifies the signal from a key fob located inside a home, purse, or pocket, while a second device relays it to the vehicle. The car is tricked into believing that the authorized key is present, allowing it to unlock and start.
Law enforcement and auto security experts report that vehicles from several major manufacturers are more commonly targeted due to widespread use of keyless systems. Models frequently cited as vulnerable include:
- Toyota and Lexus: Camry, Corolla, RAV4, Highlander, Tacoma, Lexus RX and ES
- Honda and Acura: Civic, Accord, CR-V, Pilot, Acura MDXand TLX
- Ford and Lincoln: F-150, Escape, Explorer, Mustang,Lincoln Navigator
- Hyundai and Kia: Sonata, Elantra, Tucson, Santa Fe, KiaOptima, Sportage, Telluride
- Nissan and Infiniti: Altima, Rogue, Maxima, Infiniti Q50and QX60
- BMW, Mercedes-Benz, and Audi: Multiple late-modelsedans and SUVs with comfort access or keyless features
To protect yourself, store key fobs in signal-blocking (Faraday) pouches or metal containers, especially overnight. Keep keys away from doors and windows. Check with your dealer to see if keyless entry can be disabled or updated with added security. Visible deterrents like steering wheel locks remain effective.
If your vehicle is stolen, contact law enforcement immediately and notify your insurer. Awareness is critical. Understanding how these digital thefts occur is the first step in preventing them.
