Decoding Keyless Car Thefts: Essential Security Tips for UK Vehicle Owners

Mate, did you hear about keyless car thefts? It’s scary how easy it’s become for thieves to steal cars without even touching the keys.

Picture this, you park your car outside your house, lock it, and head inside thinking it’s safe. But within minutes, a thief using a simple relay device can clone your key signal and drive off like it’s theirs.

Keyless car thefts, or “relay attacks,” are becoming a massive problem in the UK. Criminals don’t need to hotwire cars anymore, they just need the right gadget and boom, your car’s gone before you even realise it. And let’s be honest, most people don’t even think about it until it happens to them.

But here’s the good news, there are ways to fight back. From signal-blocking pouches to advanced immobilisers, securing your car doesn’t have to be complicated. Let’s break down how these thefts happen and, more importantly, how you can stop them before you become the next victim.

How Keyless Car Thefts Happen?

Keyless cars use proximity-based fobs that automatically unlock and start your vehicle when the fob is nearby. Thieves exploit this by using a relay device that extends the signal from your key, often from inside your home to your car, allowing them to unlock and start it.

This process takes just 30 seconds, and once they’re gone, tracking the vehicle becomes a challenge. Shockingly, some high-end cars are stolen and stripped for parts within hours.

How to Protect Your Car from Keyless Theft?

The good news? There are plenty of simple but effective ways to secure your vehicle:

1. Store Your Keys in a Signal-Blocking Pouch (Faraday Bag)

A Faraday pouch (also called a Faraday bag) is a signal-blocking case lined with metallic material that prevents radio signals from escaping or entering. It works by creating a protective shield around your key fob, stopping thieves from picking up and amplifying the signal for relay attacks.

How It Works:

When you place your key fob inside a Faraday pouch, it blocks electromagnetic fields, meaning your car won’t detect the key even if a thief tries to use a relay device. It’s like putting your key into a mini vault for radio waves.

Why You Need One:

Thieves use relay devices to extend this signal to your car, tricking it into unlocking and starting. A Faraday pouch completely cuts off this communication, making it impossible for thieves to steal your vehicle using this method.

How to Use It Effectively:

Always store your key fob in the pouch not just overnight but also during the day when at home or in public places.
Test the pouch by putting the key inside and trying to unlock your car. If the doors remain locked, it’s working properly.
Buy a high-quality pouch, as some cheap versions may not fully block signals. Look for RFID-blocking or signal-blocking features.

By using a Faraday pouch, you’re eliminating one of the easiest ways for thieves to steal your car, adding a simple but highly effective layer of security.

2. Keep Your Keys Away from Doors and Windows

Most keyless car thefts happen right outside people’s homes. Thieves use relay devices to scan for key fob signals from outside your house, often without even stepping onto your property.

How Thieves Exploit Key Fobs:

Key fobs continuously send out signals that your car detects when you’re nearby. Relay theft works when one thief stands close to your house with a scanning device that picks up your key’s signal, while another thief stands near your car with a second device that transmits the signal to unlock and start your vehicle.

How to Prevent This:

Store keys away from entry points: Place them in a drawer, cupboard, or a room far from the front door and windows. The further inside your home, the weaker the signal for thieves to intercept.
Use a metal container or signal-blocking box: A metal tin or safe can block key fob signals, just like a Faraday pouch. A microwave (switched off!) can even act as an improvised shield.
Be mindful of spare keys: Don’t forget that your backup key fob also emits a signal. Store it in a secure, signal-blocking location.

By simply changing where you keep your keys, you make it much harder for thieves to intercept the signal an easy habit that can significantly reduce your risk of keyless car thefts.

3. Use a Steering Wheel Lock

It may seem old-fashioned, but a steering wheel lock is one of the simplest and most effective deterrents against car theft. Thieves target vehicles they can steal quickly and quietly, and a visible lock on your steering wheel forces them to rethink their plan of keyless car thefts.

Why Steering Wheel Locks Work:

Visible deterrent – Thieves are looking for easy targets. A bulky, brightly colored lock on your steering wheel signals that stealing your car will take more effort and time. Most criminals won’t bother.
Physical barrier – Even if a thief manages to start your car, they won’t be able to steer it without removing the lock, a task that’s loud and time-consuming.
No reliance on electronics – Unlike key fobs, which can be hacked or intercepted using relay devices, a mechanical lock requires brute force to remove, making it a highly reliable security measure.

Types of Steering Wheel Locks:

Traditional bar locks – A metal bar that stretches across your steering wheel, preventing it from turning.
Full-wheel covers – Encloses most of the steering wheel, making it nearly impossible to cut through.
Pedal-to-wheel locks – Connects the steering wheel to the brake or clutch pedal, making movement impossible.

How to Use a Steering Wheel Lock Effectively:

Always lock it every time you park, even at home.
Choose a high-quality lock made from hardened steel and resistant to cutting or drilling.
Opt for a lock with a unique key pattern to prevent picking.

A small investment in a steering wheel lock can save you from the stress and financial loss of car theft. It’s a small price to pay for peace of mind and added security from keyless car thefts.

4. Install a Ghost Immobiliser

If you’re serious about stopping car thieves in their tracks, a Ghost Immobiliser is one of the most advanced security upgrades you can install. It’s an invisible, undetectable security system that prevents your car from starting unless a unique PIN code is entered even if thieves have cloned your key.

How Does a Ghost Immobiliser Work?

Unlike traditional immobilisers that rely on key fob signals, the Ghost system works by integrating directly into your car’s CAN (Controller Area Network) system. Instead of using a key, it requires you to enter a personalised sequence of button presses on your car’s existing controls, such as steering wheel buttons, window switches, or pedals before the engine can start.

Why Is It So Effective?

Stops key cloning & relay attacks – Even if criminals intercept your key’s signal or clone your fob, they won’t be able to start the car without knowing the unique PIN sequence.
Completely undetectable – No key fobs, no LED indicators, and no signals for thieves to scan or hack.
Customisable PIN code – You choose a sequence that only you know, and it can be easily changed if needed.

Additional Features:

Valet Mode – Allows you to temporarily disable the immobiliser when handing your car over for servicing without revealing your PIN.
No additional key fobs – Reduces the risk of extra devices being lost or compromised.
Works with most modern vehicles – Compatible with a wide range of car makes and models.

Why You Need One

A Ghost Immobiliser ensures that even if they bypass every other layer of security, they still can’t drive off without your secret PIN.

For around £499–£1000, installing a Ghost Immobiliser is a long-term investment in protecting your vehicle from theft. It’s discreet, effective, and one of the best ways to ensure your car stays where you parked it.

6. Use a Driveway Bollard or Security Post

If you park your car on a driveway, a driveway bollard or security post is a simple but highly effective way to deter thieves.

Why is a Bollard Effective?

Creates an extra obstacle – Thieves prefer quick, easy targets. A bollard forces them to spend extra time, making theft riskier and less appealing.
Prevents drive-away thefts – Even if they manage to start the car, they can’t move it without removing the bollard first.
Visible deterrent – Just seeing a bollard can make a thief think twice and move on to an easier target.

Types of Bollards & Security Posts

Fold-down bollards – Affordable and easy to install, they can be folded flat when not in use.
Removable security posts – Can be lifted out when needed but require a key or lock to remove.
Automatic bollards – Higher-end options that retract into the ground at the push of a button.

Installation & Cost

Basic fold-down bollards start from around low range and can be installed with basic DIY skills.
Heavy-duty, removable, or automatic bollards cost medium to high range, depending on the mechanism.

Final Thoughts

If you park outside, especially on a driveway, a bollard is one of the simplest yet most effective security upgrades you can install. Criminals go for the easiest targets and a bollard makes stealing your car a whole lot harder.
