Keyless entry is now a standard feature in cars, but it has also allowed car thieves to come up with new methods. If your vehicle has an intelligent key system from Toyota, it could become vulnerable to a relay attack, which allows thieves to steal it without actually touching your key.
Here, we demonstrate how these keyless entry thefts occur, explain why Toyota cars are commonly targeted, and outline how you can utilize specialized devices to prevent these attacks from happening.
What Is a Relay Attack?
A relay attack is a method by which thieves can steal your car by intercepting the communication signal between your car and its smart key. Here’s how it works:
1. The key continuously transmits a short signal as long as it is within range, whether at home or in the office.
2. The key signal is captured by one thief near your home or pocket, and another one captures it near your car, extending it with the use of a relay device.
3. The key sends a message to the car, making it think you are present, so it unlocks and turns on.
The process takes under a minute, leaving no sign of forced entry, which adds to the difficulty in being discovered by insurance or law enforcement.
Are Toyotas Vulnerable?
Yes—many Toyota models, especially from the last decade, feature always-on smart key fobs that are vulnerable to signal amplification. Models like the Camry, RAV4, Prius, and Highlander have been frequently targeted in relay thefts across North America and Europe.
That’s why it’s crucial to take extra precautions. Factory immobilizers and alarms are insufficient to prevent this type of tech-based theft.
How to Stop Relay Attacks: Real Solutions
The good news? With the right tools, you can block relay attacks and keep your car secure. Here are some proven strategies:
1. Use a Smart Sensor Car Security Solution
The most effective option is to install an innovative sensor car security solution, such as the one offered by AV Sales. Our system actively monitors for suspicious activity, including signal spoofing and forced entry attempts.
How it works:
- Detects abnormal signal behavior and unauthorized unlock attempts
- Includes a dedicated engine immobilizer, separate from Toyota’s built-in system
- Sends real-time alerts to your phone when interference or motion is detected
- Can automatically lock your doors if unauthorized access is detected
Our system is designed specifically for Toyota models and integrates with your existing electronics—no need to modify the factory keyless entry system.
2. Shield Your Key Fob
A more basic but still functional defense is using a Faraday pouch or box. These containers block your key fob’s signal when you’re not using it, making it invisible to relay devices.
- Store your key in a Faraday pouch at home
- Don’t leave keys near doors or windows
- Use a backup Faraday sleeve for your spare key
While this is a good habit, it’s not foolproof. That’s why we recommend combining it with a smart security system.
3. Turn Off Smart Key Fob Signals (if possible)
Some Toyota models allow you to disable the smart key signal by pressing a combination of buttons on the fob (usually “lock” and “unlock” together for at least 5 seconds). Check your owner’s manual to see if your model supports this feature.
Note: This disables keyless entry, so you’ll have to press the unlock button manually when approaching your car.
4. Install a Secondary Immobilizer
Many car thieves rely on speed. If they manage to enter the car, they want to drive off within seconds. A secondary immobilizer—like the one in AV Sales’ system—can prevent the engine from starting even if they unlock the doors.
This provides a powerful second layer of defense that factory systems cannot offer.
Take Control of Your Toyota’s Security
You don’t need to be a tech expert to stop high-tech thieves. With affordable and practical tools from AV Sales, you can block keyless entry theft, detect intrusion attempts, and thwart criminals in their tracks. Start by choosing an innovative sensor car security solution designed explicitly for Toyotas, and don’t forget to secure your key fob at home.
