Rising Keyless Car Thefts: Protect Your Vehicle from High-Tech Criminals

In recent years, car theft has evolved beyond broken windows and hotwiring. The modern threat now comes in the form of keyless car theft, also known as relay attacks. 

As this high-tech crime continues to soar across the UK, it’s vital for motorists to understand how these thefts happen and what measures can be taken to protect their vehicle. With thousands of keyless cars on British roads, the risk is real and growing.

What is keyless car theft?

Keyless car theft targets vehicles with keyless entry and ignition systems. Criminals use re

lay devices to capture the signal emitted by a car’s key fob, even if it’s inside your home. The signal is then transmitted to a second device near the vehicle, tricking it into thinking the real key is present. This allows thieves to unlock and start the car within seconds—all without touching the actual key.

According to data from the RAC and ONS, keyless theft accounts for more than 50% of modern vehicle thefts. As car manufacturers add more technology, criminals are becoming just as innovative in bypassing it.

Who is at risk?

Any vehicle with keyless entry is a potential target, but high-end brands and popular family cars are frequently targeted. Models from Audi, BMW, Ford, Mercedes, and Land Rover are among the most stolen. However, even mid-range vehicles are not exempt.

If your car was registered after 2015, chances are it has a keyless system. The convenience it offers comes with added security risks that many owners are still unaware of.

Signs your vehicle may have been targeted

• Moved wing mirrors or scuff marks around the doors
• Car alarm going off unexpectedly
• Unusual noises or interference near your home at night
• Signal jammers used to block your fob locking the vehicle

If you suspect anything suspicious, it’s important to act quickly.

How to protect your vehicle?

While the rise in keyless thefts is worrying, there are several practical steps you can take to secure your vehicle:

Use a faraday pouch: This simple accessory blocks your key fob’s signal when not in use, making it harder for criminals to intercept it.

Install a steering wheel lock: A visual deterrent that adds a physical barrier to theft.

Reprogram your key fob: Some manufacturers allow you to disable keyless entry.

Keep your keys away from doors and windows: Especially during the night.

Upgrade your car’s alarm system: Many factory alarms are basic. Enhanced aftermarket systems offer better protection.

Use driveway security cameras: Motion-activated CCTV or smart doorbells can provide crucial evidence.

Park defensively: Try to park in a garage or well-lit area when possible.

Conducting a car history check

If you’re buying a used car, it’s essential to ensure it hasn’t been previously stolen, cloned, or written off. A comprehensive car history check can uncover critical details about the vehicle’s background, including theft records, stolen status, mileage anomalies, finance status, and insurance write-offs.

This kind of car check goes beyond a simple DVLA lookup—it leverages multiple data sources to protect you from purchasing a high-risk vehicle.

The importance of a stolen car check

Keyless theft has led to a rise in cloned vehicles being sold in the used car market. Unsuspecting buyers may end up with a stolen vehicle, only to lose both the car and their money when it is reclaimed by authorities. An online stolen car check helps avoid such pitfalls by validating the car’s identity and legal status.

Even if the car appears fine during a physical inspection, a digital check may reveal hidden risks.

Recent case studies in the UK

In 2024, West Midlands Police reported over 4,000 car thefts involving keyless entry in just one year. In London, organised crime groups were dismantled after being found with sophisticated relay devices capable of stealing a vehicle in under a minute.

Drivers in Manchester and Birmingham have also reported increasing incidents, with some insurance providers raising premiums for keyless vehicles.

Insurance and legal implications

Some insurers now require proof of additional security measures before offering full cover on keyless cars. Failing to take basic steps—like using a Faraday pouch—could even affect claims if the insurer deems the vehicle wasn’t adequately protected.

Additionally, being in possession of a cloned or stolen car can lead to legal complications, even if you bought it in good faith. A car check is a small investment that could save thousands in the long run.

Final thoughts

With keyless car thefts continuing to rise, UK car owners must stay informed and proactive. Whether you’re a current owner of a keyless vehicle or in the market for a used car, vigilance is key.

Make it a habit to review your vehicle’s security, update your protection methods, and most importantly—use a trusted car history check before buying a second-hand car.

In an age where technology makes cars easier to drive, it unfortunately also makes them easier to steal. Stay one step ahead of criminals by being informed and prepared.
