Car theft is evolving, and modern key fobs, while convenient, have introduced new vulnerabilities. Cybersecurity experts are raising alarms about “Key Fob Theft,” a method where tech-savvy criminals exploit the wireless technology in your key to steal your vehicle. This isn’t just a hypothetical scenario; it’s a growing reality, demanding simple yet effective precautions from car owners.
Thieves have become adept at capturing the signal emitted by your key fob, even when it’s inside your home. Tools that facilitate this type of theft are readily available online, making it easier than ever for criminals to bypass traditional car security measures. Worse still, advanced devices can amplify your car’s radio signal, allowing thieves to access and copy your key fob signal with greater ease, ultimately leading to vehicle theft.
Moshe Shlisel, a cybersecurity veteran and CEO of GuardKnox Cyber Technologies, emphasizes the urgency of this issue. Speaking to the Detroit Free Press, he explained that the problem stems from “smart” key systems using nonsecure commercial radio waves. These systems, designed for convenience, allow for remote unlocking, ignition, and trunk access. However, this very convenience opens doors for sophisticated theft techniques. AAA also highlights the dual nature of your car key, stating on their website that it can be both a tool for convenience and a crucial element in preventing car theft.
The Mechanics of Key Fob Theft: How Thieves Steal Your Car Wirelessly
Car thieves are no longer limited to traditional methods like breaking steering columns. They are now employing sophisticated cyberattacks to steal vehicles or valuable car parts. To combat this evolving threat, car owners need to understand the common methods of key fob theft:
Relay Attacks: Amplifying Signals to Unlock Your Car
The “Relay Attack” is a coordinated effort typically involving two individuals. One thief approaches your home with equipment designed to capture and amplify the signal from your key fob, which might be inside your house. This amplified signal is then relayed to an accomplice waiting near your car. Equipped with another device, the accomplice receives the relayed signal, tricking the car into thinking the key fob is nearby. This allows them to unlock and start the vehicle. As reported by AARP, this method effectively bypasses your car’s security system by exploiting the key fob’s signal range.
Code Grabbing: Intercepting Your Key Fob’s Signal
“Code Grabbing” is another prevalent technique, often executed in public parking lots. When you press your key fob to lock your car, the device emits a radio frequency signal. Thieves using code-grabbing devices can intercept this signal and copy your unique code. These devices, readily available for a few hundred dollars, along with reprogrammable key fobs, make this a financially accessible method for criminals.
AARP explains that code grabbing eliminates the need for thieves to track cars to owners’ homes. They can target specific car models in public places, intercepting lock signals and gaining unauthorized access. Therefore, being aware of your surroundings and physically locking your car with the door button instead of relying solely on the remote lock can add an extra layer of security.
The ease with which key fob signals can be copied is concerning. Moshe Shlisel notes that even maintenance workers sometimes use similar cloning techniques for legitimate purposes like resetting remote control systems in gated communities, highlighting the simplicity of the technology.
Reports from the Master Locksmiths Association in Warwickshire, England, indicate that copying a key fob signal and stealing a car can occur in as little as 20 to 30 seconds, emphasizing the speed and efficiency of these modern theft methods.
Simple Yet Effective Ways to Prevent Key Fob Theft
Protecting your key fob is crucial in preventing car theft. According to cybersecurity expert Moshe Shlisel, the most effective preventative measure is to store your key fob in a metal container or a Faraday cage, such as a metal wire bag. This simple action blocks the key fob from communicating wirelessly, preventing hackers from intercepting its signal. Leaving your key fob exposed on a counter or in a pocket makes it vulnerable to hacking at any time.
The accessibility of hacking tools and online tutorials has further exacerbated the problem. Five years after initially warning about key fob hacking, Shlisel points out that cloning devices and instructions are now easily found online, making it even simpler for criminals to steal vehicles.
Preventing key fob signal cloning is achievable with straightforward steps. Shlisel advises against leaving key fobs near doors or close to parked vehicles. Maximizing the distance between your key fob and your car reduces the risk of signal interception.
The Faraday Cage Solution: Using Metal to Block Signals
Employing a Faraday cage, or a simple metal container, disrupts the communication between your key fob and potential hacking devices. This shielding effectively blocks electromagnetic fields, preventing thieves from capturing your key fob’s signal. This method is a low-tech yet highly effective solution to a high-tech problem.
Distance Matters: Keeping Your Key Fob Far From Your Car
The wireless communication between your key fob and car relies on proximity. By increasing the distance between your key fob and your vehicle when at home, you significantly decrease the risk of relay attacks. Think of it as creating a “dead zone” where the signal cannot be effectively intercepted and amplified by thieves operating outside your home.
Key Fob Hacking: A Growing Trend Backed by Technology and Online Resources
The underlying mechanism of key fob and vehicle communication is based on “pairing,” similar to Bluetooth connections between devices like smartphones and headsets. Moshe Shlisel explains this by drawing a parallel to disconnecting Bluetooth devices to disrupt communication. Disrupting this “pairing” is the core principle behind preventing key fob theft.
While researchers have explored more secure methods to prevent code copying, these solutions are often expensive. Replacing a key fob can already cost up to $1,000, making widespread implementation of advanced security features challenging. According to Shlisel, attempts to implement more secure methods have faced difficulties.
The vulnerability lies in the cloning of communication signals when you press the lock or unlock button on your key fob. This cloned signal can then be used to gain unauthorized access to your vehicle. For those living in areas prone to car theft or when engaging in activities like skiing or boating, it’s especially crucial to avoid leaving key fobs inside the vehicle, where they are most vulnerable. As a last resort, wrapping your key fob in multiple layers of aluminum foil can also effectively block the signal, providing a makeshift Faraday cage.
Real-World Examples: Key Fob Theft Incidents and Rising Car Theft Statistics
Recent incidents highlight the reality of key fob theft. In Ann Arbor, Michigan, police investigated thefts in November that appeared to be linked to key fob vulnerabilities. Kevin Cox, an Ann Arbor resident, experienced this firsthand when his truck was stolen from his home, despite both sets of keys being inside. Security footage from a neighbor showed thieves using an SUV and a device to steal his Ford F-150, even disabling the vehicle’s location tracking feature.
Similar car hacking incidents have been reported in Texas and Florida, indicating a widespread issue.
National Car Theft Statistics: The Alarming Numbers
Data from the National Insurance Crime Bureau (NICB) reveals a concerning trend. Car theft in the U.S. continues to reach “near record levels.” In the first half of 2023 alone, nearly 500,000 vehicles were reported stolen nationwide, marking a more than 2% increase compared to the same period in 2022. This data underscores the escalating threat of vehicle theft, with key fob hacking contributing to these alarming statistics.

Conclusion: Take Key Fob Theft Seriously and Protect Your Vehicle Today
Key fob theft is not a futuristic threat; it’s a present-day reality. By understanding how these thefts occur and taking simple preventative steps, like storing your key fob in a metal container and keeping it distanced from your vehicle, you can significantly reduce your risk. As car theft methods become more sophisticated, proactive measures to protect your key fob are essential for safeguarding your vehicle.
