The Evolution of Car Theft Techniques
Car theft in the United States has transformed significantly, with criminals increasingly exploiting vulnerabilities in keyless entry systems. Traditional methods such as hot-wiring are being replaced by high-tech tactics, notably relay attacks and signal hijacking. These methods allow thieves to unlock and start vehicles within seconds, often without leaving any physical evidence. In 2023, over one million vehicles were reported stolen, marking the highest figure in over a decade. Despite a decline in overall car thefts—down 17% to approximately 850,000 vehicles in 2024, and a further 23% drop in the first half of 2025—keyless cars remain prime targets.
Keyless Entry Vulnerabilities
Relay attacks account for over 80% of keyless car thefts in the U.S. This technique involves two criminals: one captures the signal from the owner's key fob, while the other uses a device to unlock the car. The tools for these attacks are inexpensive and widely available online, with social media platforms like TikTok contributing to the spread of tutorials. A notable trend, dubbed the "Kia Challenge," emerged, where groups like The Kia Boyz showcased their ability to steal Kia and Hyundai vehicles, leading to numerous thefts, joyriding incidents, and associated fatalities.
Corporate Responses to Theft Concerns
In response to the growing issue, Hyundai and Kia announced a free hardware fix for millions of vehicles lacking essential anti-theft technology. This decision followed a settlement with Arizona Attorney General Kris Mayes and 34 other attorneys general, mandating that all future U.S. models include engine immobilizers. Additionally, reports indicate that Tesla Model 3 and Model Y vehicles are also vulnerable to Bluetooth low energy (BLE) relay attacks, which can bypass security features if not properly configured.
Broader Trends and Recommendations
The trend of keyless car theft is not limited to the U.S.; similar patterns are emerging in the UK, where 58% of vehicle thefts from April 2023 to March 2024 involved signal manipulation, a fourfold increase since 2018-2019. The U.S. National Insurance Crime Bureau identified the most stolen vehicles in the first half of 2025 as keyless models, including the Hyundai Elantra, Honda Accord, and Chevrolet Silverado 1500.
To mitigate the risk of theft, experts recommend several precautions. These include using Faraday pouches to block key fob signals, parking in secure areas, and employing visible deterrents like steering wheel locks. Additionally, keeping keys away from doors and windows, installing surveillance systems, and utilizing GPS tracking devices can enhance security.
Official Statements & Responses
Hyundai and Kia's commitment to enhancing vehicle security through hardware fixes reflects a growing recognition of the vulnerabilities associated with keyless entry systems. The National Insurance Crime Bureau emphasizes the importance of proactive measures by vehicle owners to safeguard their cars against theft.
Verbatim Quotes
“While not among the top 10 most stolen cars by volume, Tesla’s vulnerability is notable because the attack exploits the convenience of phone-as-key and BLE fobs, similar to attacks on other brands using BLE for entry/start,” — Autoblog
“Software updates from manufacturers may include security patches, so keeping your car’s system current could be the difference between keeping it and losing it.” — Security Expert
Conflicting Reports & Gaps
While the overall trend indicates a decline in car thefts, the specific rise in keyless car thefts presents a complex picture. Some sources report varying statistics on the effectiveness of different anti-theft measures, highlighting the need for ongoing research and adaptation in vehicle security technologies.
