Keyless Car Theft: How Relay Attacks Work & How To Protect Your Vehicle

21 January 2026 Uncategorised

Keyless car theft has become the fastest-growing vehicle crime in the UK, with criminals now able to steal your car in under 60 seconds without ever touching your keys. According to the Crime Survey for England and Wales, 58% of all car thefts between March 2023 and 2024 involved criminals manipulating keyless entry systems. (Source:Auto Express) With a car being stolen every five minutes in the UK, understanding how these attacks work and how to protect yourself has never been more important.

At W4G Track Recovery, we’ve seen first-hand how devastating keyless car theft can be for vehicle owners. Whether you’re a private car owner, car rental company, or managing a commercial fleet, the threat is ongoing. The good news? With the right knowledge and security measures, you can significantly reduce your risk and ensure your vehicle can be recovered through professional stolen vehicle recovery services if the worst happens.

What Is Keyless Car Theft?

Keyless car theft, also known as relay theft or relay attack, is a method criminals use to steal vehicles equipped with keyless entry and start systems. Unlike traditional car theft that required breaking windows or hot-wiring ignitions, relay theft exploits the wireless signals your key fob constantly emits.

Your keyless fob sends out a short-range signal that your car recognises when you’re nearby. This is what allows you to unlock doors and start the engine without pressing any buttons. Criminals have found ways to capture, amplify, and relay this signal to trick your car into thinking the key is present, even when it’s safely inside your home.

How Common Is Keyless Car Theft In The UK?

The statistics paint a concerning picture:

How Do Relay Attacks Work?

A relay attack typically involves two criminals working together with electronic devices that can be purchased online for as little as £80-£100.

Step-by-step: The Relay Attack process

Step 1: Signal Detection
One thief positions themselves near your home, often by the front door or a window, holding a device that can detect and capture the signal from your key fob. These devices can pick up signals from over 100 metres away.
Step 2: Signal Amplification
The captured signal is instantly transmitted to a second device held by an accomplice standing next to your vehicle on the driveway or street.
Step 3: Vehicle Access
The second device tricks your car into thinking the genuine key fob is nearby. The car unlocks automatically, just as it would if you were standing there with your keys.
Step 4: Engine Start
With the doors open, the thief enters the vehicle and presses the start button. The car starts normally because it still believes the key is present.
Step 5: Getaway
The entire process takes as little as 30-60 seconds. The criminals drive away, often to a “chop shop” where the vehicle is stripped for parts or prepared for export.

Other methods criminals use

While relay attacks are the most common, thieves also employ other sophisticated methods:

  • Signal jamming: Blocking your key fob’s lock signal so your car remains unlocked when you walk away
  • Key cloning: Using diagnostic tools to programme blank keys to work with your vehicle
  • CAN bus attacks: Plugging devices into your car’s diagnostic port to bypass security systems
  • OBD port hacking: Accessing the on-board diagnostics to reprogram new keys

Which Cars Are Most At Risk?

Any vehicle with keyless entry is potentially vulnerable, but some models are targeted more frequently due to their value, demand for parts, or known security weaknesses.

Most stolen cars in the UK (2024)

According to DVLA data analysed by What Car?, the most frequently stolen vehicles include:
1.  Ford Fiesta – 4,719 thefts
2.  Volkswagen Golf – High demand for parts
3.  Ford Focus – Popular and widely available
4.  Range Rover – High value and export demand
5.  BMW 3 Series – Luxury appeal and resale value
6.  Mercedes C-Class – 323 thefts per 100,000 vehicles
7.  Toyota RAV4 – Catalytic converter and parts value

Premium brands like Range Rover, BMW, Mercedes, and Audi are particularly targeted by organised criminal gangs who steal to order for export markets.

Real-Life Recovery: Why GPS Tracking Matters

Whether your vehicle is taken through a relay attack, key theft, or any other method, GPS tracking dramatically increases your chances of recovery.

Even with the best prevention measures, determined criminals can still steal vehicles. That’s where professional recovery becomes essential.
At W4G Track Recovery, we’ve successfully recovered vehicles from organised crime operations across the UK. In one Essex operation, our team traced multiple stolen Range Rovers to a suspected chop shop, working with police to recover the vehicles and arrest suspects. In another case, a stolen Mercedes was located and secured within hours despite limited police resources.

With a 95% recovery rate and an average recovery time of just 4.4 hours, our GPS tracking devices and stolen vehicle recovery services give you the best chance of getting your vehicle back. View more of our case studies to see how we’ve helped clients recover their assets.

How To Protect Your Car From Keyless Theft

Here are the key tips for keyless car owners:

  • Use a Faraday pouch to block your key fob signal
  • Store keys away from doors and windows – the middle of your home is safest
  • Install a steering wheel lock as a visible deterrent
  • Invest in a GPS tracker – even if thieves steal your car, you can recover it

Why prevention alone isn’t enough

Even with all preventative measures in place, determined criminals with sophisticated equipment can still steal vehicles. That’s why recovery capability is just as important as prevention.

The reality of vehicle recovery without a tracker

  • 68% of stolen vehicles are never recovered (Source: Fleet News)
  • Recovered vehicles without trackers are often found stripped or damaged
  • Police resources are limited, with many vehicle crimes closed without investigation
