Introduction
Keyless entry systems have changed the way we use our cars. Instead of struggling with traditional keys, we can now simply press a button or use proximity detection to unlock our vehicles. These smart systems let us open doors, start the engine, and secure the car without needing a physical key.
The convenience is clear. We can keep our key fob in our pocket or bag while doing other tasks like loading groceries, taking care of children, or carrying work items. Our car automatically recognizes us and responds, making our daily routines easier and more efficient.
But there’s a downside to this modern convenience.
Car thieves have found ways to exploit keyless entry systems. They can intercept and clone key fob signals, potentially gaining access to your vehicle without permission in seconds.
This guide will show you how to protect your car from keyless entry scams. We’ll share both technological solutions and practical security measures to help keep your vehicle safe.
Understanding Keyless Entry Systems
Your key fob is like a small radio transmitter that sends out a unique encrypted signal to your car. When you get close to your vehicle, this signal activates the receiver inside the car, which unlocks the doors automatically when you’re within a certain distance – usually between 5 to 20 feet.
Common Features of Modern Key Fobs
Most modern key fobs come with several standard features:
- Passive Entry: Doors unlock automatically when you’re near the vehicle
- Push-Button Start: Start the engine without inserting a physical key
- Remote Lock/Unlock: Control door locks from a distance
- Panic Button: Trigger the car alarm in emergency situations
- Trunk Release: Open the trunk or liftgate remotely
The Security Risk: Relay Attacks
While these systems offer convenience, they also have a significant security weakness known as relay attacks. In this type of theft, criminals use specialized devices to intercept and amplify the signal from your key fob, even if it’s inside your home.
Here’s how a typical relay attack works:
- One thief places a relay device near your home’s entrance or windows
- Another thief stands by your car with a second relay device
- The first device captures the signal from your key fob
- The captured signal is boosted and sent to the second device
- Your car receives this amplified signal and thinks it’s legitimate
- The vehicle unlocks, allowing thieves to start the engine and drive away
This entire process can happen in just a few seconds, making relay attacks particularly dangerous. The equipment needed for this method is easily accessible online for a few hundred dollars, which is why it has become increasingly popular among car thieves.
Why Are Keyless Entry Systems Vulnerable?
The vulnerability of keyless entry systems lies in the constant communication between your key fob and vehicle. Whenever your car sends out a signal, your key fob automatically responds without any action required from you. This automated response creates an opportunity for thieves to exploit and manipulate the system.
For instance, hackers can employ advanced techniques such as hijacking vehicle entry systems through methods that further compromise these security measures. Understanding how keyless entry systems work and their potential vulnerabilities can help you take necessary precautions to protect your vehicle from such attacks.
Moreover, there are strategies available for mitigating vulnerabilities in keyless entry systems, which can significantly enhance your vehicle’s security against these types of threats.

Preventive Measures Against Keyless Entry Scams
Protecting your vehicle from keyless entry scams requires a multi-layered approach to security. You can implement several proven prevention strategies to safeguard your car against unauthorized access.
1. Signal Blocking Techniques
Signal blocking stands as a primary defense against relay attacks. A Faraday bag creates an electromagnetic barrier that blocks radio frequency signals from reaching or leaving your key fob. These specialized pouches use metallic mesh or fabric to form a protective cage around your keys.
Here’s what you need to know about signal blocking:
- Faraday Pouches: Made with specialized materials that prevent thieves from intercepting your key’s signal
- Testing Method: Place your key fob in the pouch and stand next to your car – if the doors don’t unlock, your pouch works effectively
- Price Range: Quality signal blocking pouches cost between $15-50, making them an affordable security investment
Signal blocking alternatives include:
- Aluminum foil wrapping (temporary solution)
- Metal containers
- Signal blocking boxes for home storage
- RFID-blocking wallets designed for car keys
The effectiveness of signal blocking depends on proper usage. Your key fob must remain inside the protective container whenever you’re not actively using your vehicle. Some vehicle owners keep two pouches – one for home storage and another for on-the-go protection.
The latest generation of signal blocking pouches includes visual indicators that confirm active signal blocking, giving you peace of mind that your keys are protected. These pouches work with most vehicle brands and can block signals from multiple key fobs simultaneously.
2. Disabling Wireless Signals When Not In Use
Many modern vehicles offer built-in options to deactivate wireless signals on key fobs. You can disable the keyless entry function through your vehicle’s infotainment system or dashboard settings. Some manufacturers include a specific button sequence on the key fob – pressing it twice deactivates the wireless transmission.
- Navigate to “Vehicle Settings” in your car’s menu
- Look for “Keyless Access” or “Remote Entry”
- Select “Disable” or “Turn Off”
- Check your owner’s manual for model-specific instructions
- Double-press the lock button
- Press and hold both lock and unlock buttons
- Remove the physical key to disable wireless functions
This security measure proves particularly effective during nighttime hours when most relay attacks occur. The temporary signal deactivation creates a robust defense against unauthorized access attempts.
3. Physical Security Enhancements
Physical security measures create visible deterrents that make thieves think twice before targeting your vehicle. A steering wheel lock serves as both a visual and physical barrier, making it significantly harder for thieves to drive away with your car even if they bypass the keyless entry system.
Essential physical security measures include:
- High-quality steering wheel locks with pick-resistant locks
- Visible alarm systems with flashing LED indicators
- Wheel clamps for extended parking periods
- GPS tracking devices hidden within the vehicle
Your parking location plays a crucial role in vehicle security. Select spots that are:
