Key Fob Protector From Theft: The Expert Guide

Discover how a key fob protector can shield your car from theft and learn expert tips to secure your keyless entry vehicle. Keyless car theft, also known as relay theft, is a growing concern for vehicle owners. This guide will explain what it is, how it works, and most importantly, how a key fob protector can be your first line of defense against this modern crime.

Understanding Keyless Car Theft: Relay Theft Explained

Keyless car theft, often referred to as relay theft or relay crime, involves thieves exploiting the technology of keyless entry systems. These systems are designed for convenience, allowing you to unlock and start your car without physically using a key. However, this convenience has created a vulnerability. Thieves use readily available devices to capture and amplify the signal emitted by your key fob. This trickery fools your car into thinking the key is nearby, granting them access to unlock and even start your vehicle, all without needing your actual key.

How Relay Theft Works: Step-by-Step

The process of keyless car theft is surprisingly quick and efficient, often taking as little as 20 to 30 seconds. Here’s how it typically unfolds:

Step 1: Signal Interception: A thief uses a relay device near your home or wherever your car keys are located. This device scans for and captures the radio signal emitted by your key fob.

Step 2: Signal Relay: The captured signal is then relayed to a second thief standing near your car. This accomplice uses another device to transmit the amplified signal to your vehicle.

Step 3: Vehicle Deception: Your car, tricked into believing the legitimate key fob is in close proximity, unlocks its doors and disarms the immobilizer. In many cases, this also allows the thieves to start the engine and drive away.

The proximity needed for thieves to capture your key signal is surprisingly short, just a few meters. This means even if your keys are inside your house, near a door or window, they could be vulnerable.

Is Your Car at Risk? Identifying Keyless Entry Systems

Not all cars are vulnerable to relay theft. The risk is specific to vehicles equipped with keyless entry systems. Here’s how to determine if your car has keyless entry:

  • Keyless Entry System: If you can unlock, and in many cases, start your car without pressing any buttons on your key fob, it’s likely you have a keyless entry system. The car automatically detects the key fob when it’s within a certain range.
  • Traditional Remote Entry: If you need to press a button on your key fob to unlock your car, your vehicle is not susceptible to relay theft. These systems don’t constantly emit a signal that thieves can intercept.

If you are still unsure, consult your car’s manual or contact your car manufacturer to confirm if your vehicle has a keyless entry system.

The Key Fob Protector: Your First Line of Defense

A key fob protector, also known as a Faraday bag or signal blocking pouch, is a simple yet highly effective way to prevent relay theft. These protectors are designed to block electromagnetic fields, including the radio waves emitted by your key fob.

How Key Fob Protectors Work:

Key fob protectors are typically made from materials like metallic fabric or mesh that create a Faraday cage. This cage effectively blocks radio signals from escaping or entering. When you place your key fob inside a protector, the signal is contained, preventing thieves from intercepting it with a relay device.

Benefits of Using a Key Fob Protector:

  • Signal Blocking: Effectively blocks the radio signals from your key fob, preventing relay theft.
  • Peace of Mind: Provides reassurance that your car is protected against this type of theft.
  • Affordable Security: Key fob protectors are relatively inexpensive, offering a cost-effective security solution.
  • Easy to Use: Simple to use – just place your key fob inside the pouch when not in use.
  • Versatile Protection: Some protectors also block Wi-Fi and Bluetooth signals, adding an extra layer of digital security for your devices.

Beyond Key Fob Protectors: Additional Anti-Theft Measures

While a key fob protector is a crucial tool, consider these additional measures to further enhance your car’s security:

1. Deactivate Keyless Fob Wireless Signal (If Possible):

Some keyless fobs have a feature that allows you to manually deactivate the wireless signal. Check your car’s manual or contact the manufacturer to see if this option is available for your vehicle. Disabling the signal when not in use adds another layer of security.

2. Utilize Steering Wheel Locks and Car Alarms:

Physical security devices like steering wheel locks can be a significant deterrent to thieves. While modern car thieves often rely on electronic methods, a visible mechanical lock can make them think twice. Similarly, a car alarm system, especially a Thatcham-approved system, can deter thieves and potentially lower your car insurance premiums.

3. Park Strategically:

Where you park your car can also impact its vulnerability. Parking in a garage is ideal as it adds a physical barrier and increases the distance between your car and potential thieves. If you park on a driveway, park as close to your house as possible. When parking on the street, choose well-lit areas.

4. VIN Etching:

Etching your Vehicle Identification Number (VIN) onto your car’s windows and headlights makes it more difficult for thieves to resell stolen parts or the entire vehicle. This added identification can deter theft and aid in recovery if your car is stolen.

5. Keep Your Car Tidy and Discreet:

Avoid leaving valuable items in plain sight inside your car. This reduces the temptation for opportunistic thieves. Also, be mindful of leaving marks from GPS suction cups or other signs of expensive equipment that might attract unwanted attention.

6. Secure Lost or Spare Keys:

If you lose your car keys, it’s crucial to reprogram your locks and keys immediately with a certified auto locksmith. This prevents any stolen or lost keys from being used to access your vehicle. Similarly, when buying a used car, consider reprogramming the keys to ensure no previous owners have access.

7. Reprogram Car Keys for Used Vehicles:

When purchasing a second-hand vehicle, reprogram your car keys. This will ensure that any keys from previous owners are no longer valid, enhancing your vehicle’s security from potential past access.

Car Models at Higher Risk

While any car with keyless entry is potentially vulnerable, certain models have been identified as being at higher risk due to security vulnerabilities. Popular models like Ford Fiesta, Volkswagen Golf, Nissan Qashqai, and Ford Focus have been reported as frequent targets for relay theft. Organizations like Thatcham Research and ADAC have conducted tests on various keyless entry vehicles, highlighting those with weaker security systems.

Keyless Entry Cars Passing Security Tests (Superior Rating):

  • Audi e-tron
  • BMW 1 Series / 7 Series / 8 Series
  • BMW X6 / X7
  • Ford Puma
  • Jaguar XE
  • Land Rover Evoque
  • Mercedes B-Class
  • Porsche 911
  • Porsche Macan
  • Volkswagen Passat

Keyless Entry Cars Failing Security Tests (Poor Rating):

  • DS3 Crossback
  • Ford Mondeo
  • Kia ProCeed
  • Lexus UX
