Keyless Entry Vehicle Theft in the UK: What Every Motorist Needs to Know

In today’s motoring world, the keyless entry vehicle has become a standard feature. The technology offers convenience, modern styling, and a seamless driving experience. With just a touch of a button or proximity detection, drivers can unlock, start, and secure their car without taking the key fob out of their pocket.

However, the same technology that provides convenience also presents risks. Criminals have found ways to exploit the signals emitted by key fobs, and the UK is now experiencing rising cases of keyless entry vehicle theft. For Motor Bridge readers, understanding how this crime works and what steps you can take to protect your car is essential.

What is Keyless Entry Vehicle Theft?

Keyless entry vehicle theft, often called relay theft, occurs when criminals use a signal amplifier and a transmitter to capture the communication between a key fob and a car. Even if the key fob is safely inside your home, thieves can extend its signal to unlock and start the vehicle.

The process is alarmingly quick:

• Thieves use a relay device to pick up the key fob signal.

• A second device transmits that signal to the vehicle.

• The car interprets the signal as legitimate, unlocks the doors, and starts the engine.

This method means criminals don’t need to break into your home or physically steal the keys. It’s discreet, fast, and increasingly common in urban and suburban areas where keyless entry vehicles are parked on driveways or near houses.

Is Your Car at Risk?

If you own a keyless entry vehicle, your car is at greater risk compared to those with traditional locking systems. Premium cars and high-demand models are particularly targeted because of their resale value and desirability.

Even if you believe your keys are safe — perhaps on a kitchen counter or hanging by the door — relay devices can pick up the signal through walls, doors, and windows. Tests have shown that some devices can capture a signal from up to 30 metres away.

The truth is simple: if your car uses a keyless system, it is vulnerable unless you take preventative action.

How to Protect Your Keyless Entry Vehicle

The good news is that while criminals are taking advantage of technology, motorists also have access to effective tools and habits that reduce the risk. Here are the most reliable ways to protect a keyless entry vehicle:

1. Use a Faraday Bag or Signal-Blocking Pouch

A Faraday pouch is one of the most cost-effective defences. These lined bags block the electromagnetic signal from your key fob, preventing it from being intercepted.

• Always store your keys inside the pouch when not in use.

• Test the pouch by placing the key inside and attempting to unlock the car.

• Don’t forget your spare key — thieves often target households where a backup key is stored nearby.

2. Invest in a Steering Lock

While they may seem old-fashioned, steering wheel locks remain highly effective. A visible lock deters thieves because it adds time and effort to the theft process.

• Full-wheel locks, such as the Disklok, cover the entire steering wheel and are police-recommended.

• They provide both a physical and visual deterrent, making your keyless entry vehicle a less attractive target.

3. Switch Off the Key’s Signal (If Possible)

Some manufacturers allow drivers to disable the wireless signal on their key fob when it is not in use.

• Check your vehicle manual or contact your dealer to see if this option is available.

• Switching off the signal is especially useful when travelling or parking in unfamiliar locations.

4. Use a Driveway Security Post or Wheel Clamp

If you park on a driveway, adding a security post or heavy-duty wheel clamp makes theft far more difficult. Thieves typically avoid cars that require multiple tools and steps to steal.

Combining a driveway post with a steering lock adds layered protection for your keyless entry vehicle.

5. Keep Software Updated

Manufacturers are releasing software updates to improve keyless system security.

• Ask your dealer or service centre to check if updates are available.

• Schedule software checks during routine servicing to ensure your keyless entry vehicle has the latest protections.

Wider Vehicle Security Tips

Protecting a keyless entry vehicle should go beyond just the fob. A layered approach reduces risk significantly:

• CCTV or smart doorbell cameras: Visible security cameras can deter thieves and provide evidence if theft occurs.

• Motion-activated lighting: Criminals often target dark driveways. Bright lights can discourage attempts.

• Neighbourhood awareness: Sharing information about suspicious activity helps protect whole communities.

By combining digital and physical security, you make your vehicle a much harder target.

Why Keyless Entry Vehicle Theft is Increasing

The rise in keyless entry vehicle theft can be attributed to three main factors:

1. Availability of equipment: Relay theft devices are becoming cheaper and more accessible online.

2. High resale value: Stolen vehicles are quickly sold or stripped for parts.

3. Consumer habits: Many drivers unknowingly make it easier for thieves by leaving keys near doors or windows.

Reports from police forces across the UK confirm that keyless entry vehicles are among the most targeted, especially in large cities.

Industry and Policy Response

The automotive industry is responding to the risks. Manufacturers are investing in more secure keyless systems, such as motion-sensor fobs that deactivate when not in use. The DVLA and UK insurers are also monitoring theft patterns closely.

• Insurance impact: Drivers of certain keyless models may face higher premiums unless additional security is demonstrated.

• Manufacturer commitments: Some brands now include Faraday pouches with new keyless entry vehicles.

• Government initiatives: There is ongoing research into standards for vehicle cybersecurity to help reduce theft.

These efforts show recognition of the problem, but motorists still need to take proactive steps themselves.

Everyday Habits That Make a Difference

Sometimes, the simplest actions can have the biggest impact. If you own a keyless entry vehicle, keep these habits in mind:

• Store keys away from windows and doors.

• Always lock your car, even on driveways.

• Avoid leaving valuables inside vehicles overnight.

• Park in well-lit areas when away from home.

• Regularly review your security measures.

Staying consistent with these habits reduces your risk significantly.
