How to Protect Your Car from Keyless Theft?
Keyless theft, also known as relay theft or signal jacking, is a serious concern for car owners these days. Thieves have developed sophisticated methods to exploit the weaknesses in keyless entry systems, allowing them to steal cars without having the physical keys. But don’t worry, this article will guide you through the best practices to protect your car from keyless theft.
Understanding How Keyless Theft Works
Before we dive into the protection methods, it’s essential to understand how keyless theft works. Modern cars equipped with keyless entry systems use radio frequency signals to communicate with the vehicle’s computer. These signals are broadcast by the remote key fob, and the car responds by recognizing the signal and unlocking or starting the engine.
Attackers can exploit this vulnerability by using specialized devices that amplify the signal from the remote key fob, tricking the car into thinking the keys are nearby. This enables them to steal the car without physically having the keys.
Signs That Your Car Is Vulnerable to Keyless Theft
Before we get into protection methods, it’s essential to identify the signs that your car might be vulnerable to keyless theft.
- If your car has a keyless entry system: Modern cars are more likely to have a keyless entry system.
- If your car has a push-button start: If your car can be started without inserting the key, it’s more likely to be vulnerable to keyless theft.
- If your car has proximity sensors: If your car has proximity sensors that sense the remote key fob’s presence, it may be more susceptible to attack.
Ways to Protect Your Car from Keyless Theft
Now that we’ve identified the vulnerability, let’s dive into the ways to protect your car from keyless theft.

1. Use a Faraday Pocket or Faraday Bag
A Faraday pocket or bag is a simple, affordable, and effective way to protect your remote key fob from signal amplification. This pouch or bag is made of a specific material that blocks radio signals, preventing the signal from being amplified and stolen. You can purchase Faraday pockets or bags online or make your own DIY version using a metal-coated material.
Pros: Affordable, simple to use, and provides excellent protection.
Cons: May affect the operation of your phone or other devices when in the Faraday pocket.
2. Update Your Vehicle’s Software
Regularly update your vehicle’s software to ensure that the latest security patches are installed. Many car manufacturers release software updates to address security vulnerabilities. Check with your dealership or the manufacturer’s website to see if any software updates are available for your vehicle.
Pros: Free or low-cost, and helps to strengthen your vehicle’s security.
Cons: May take some time to complete, and may require a professional to install.
3. Use a Device Locking Device
A device locking device, like a signal blocking device or a jamming device, can be used to interrupt the signal amplification attack. These devices emit a signal that overwhelms the attacker’s device, rendering it ineffective. Choose a reputable brand and read reviews before purchasing.
Pros: Effective at blocking signals, and comes in various forms (wristbands, key fobs, etc.).
Cons: May not work with all types of vehicles, and may require activation.
4. Keep Your Remote Key Fob Secure
Keep your remote key fob close and secure, away from potential thieves. Stash it in a metal box or a Faraday pocket, or keep it in a safe place.
Pros: Keeps your remote key fob safe and secure.
Cons: May require regular checking to ensure the pouch or box is still available.
5. Consider a GPS Tracker and Immobilizer
In addition to the above measures, consider installing a GPS tracker and immobilizer in your vehicle. A GPS tracker allows you to monitor your vehicle’s location, speed, and other parameters. An immobilizer prevents your vehicle from starting without the correct key.
Pros: Provides additional layers of security, and makes it easier to recover the vehicle.
Cons: May require installation by a professional, and may not be compatible with all types of vehicles.
In Conclusion
Keyless theft is a serious concern that requires attention. By implementing the above measures, you can significantly reduce the risk of your car being stolen. Remember to be proactive, keep your remote key fob secure, update your vehicle’s software regularly, and consider additional layers of security.
Table: Comparison of Faraday Pockets and Jamming Devices
| Features | Faraday Pocket/Jamming Device | |
|---|---|---|
| Effectiveness | Blocks all signals, jamming | Blocks signals, but doesn’t jam |
| Size | Small, portable, and lightweight | Larger and heavier |
| Cost | Affordable (less than $20) | More expensive (average $50) |
| Ease of use | Simple, just slide in your key fob | Requires setup and adjustment |
In conclusion, it’s essential to take action to protect your car from keyless theft. Implement the measures mentioned above to ensure your car remains safe and secure.
