UK Car Theft Statistics 2025 — And How Mobile Immobilisers Cut Risk by 87%

The Scale of the Problem

Car theft in the UK is experiencing its worst period in two decades. According to Home Office Crime Statistics (England and Wales, 2024), approximately 130,000 vehicles were reported stolen — a figure that does not include the additional 200,000+ estimated unreported incidents.

For context, that is roughly one vehicle stolen every 4 minutes, 24 hours a day.

The Association of British Insurers (ABI) reported that vehicle theft claims reached £1.4 billion in 2024 — a record figure, and a 40% increase over five years.

Why Theft Is Rising: The Keyless Entry Vulnerability

The primary driver of increased theft is the widespread adoption of keyless entry and push-button start systems. By 2025, an estimated 70% of new vehicles sold in the UK feature proximity key fobs — and most factory immobiliser systems were not designed to stop relay attacks.

How a relay attack works:

1. Thief A stands outside your home with a signal relay device near your front door
2. Thief B stands next to your car with a matching receiver
3. The devices amplify your key fob’s signal from inside the house — even from 30+ metres away
4. The car’s immobiliser accepts the amplified signal as genuine and disarms
5. The thieves open the car, start the engine, and drive away

Total time: under 60 seconds. No damage. No alarm. No evidence.

2025 UK Car Theft Statistics at a Glance

The Most Stolen Vehicles in the UK (2025)

Based on police force data compiled by the DVLA and Which?:

1. Land Rover Range Rover / Defender — #1 for 6 consecutive years
2. Ford Focus — high volume means high absolute theft numbers
3. VW Golf — popular and resaleable parts
4. BMW 3 Series — target for keyless relay attacks
5. Mercedes-Benz C-Class — high resale value, frequently shipped overseas
6. Toyota RAV4 — relay-vulnerable hybrid system
7. Ford Transit — fleet vehicles often lack upgraded security

What Thieves Do With Stolen Vehicles

Understanding the supply chain helps explain why prevention matters more than recovery:

• Exported within 24 hours — approximately 40% of high-value stolen vehicles leave the UK within a day, making recovery near-impossible
• Stripped for parts — VIN plates changed, parts sold through online marketplaces
• Sold with false documentation — “clone” cars with replaced plates

This explains why the recovery rate has fallen from 65% (2000) to 28% (2024). Physical barriers like GPS trackers help police recover recovered vehicles, but they do nothing to prevent the initial theft.

How CAN Bus Immobilisers Work Against Relay Attacks

A modern CAN bus immobiliser works on a simple but powerful principle: the car requires two separate authentication factors to start, not one.

Factor 1: Your key fob (which thieves can replicate via relay attack) Factor 2: Your immobiliser’s authorisation (which they cannot replicate)

The CarGuard CAN immobiliser installed by TuneCar operates via Bluetooth proximity authentication. When the driver’s paired smartphone is not within range, the immobiliser remains active — regardless of what the key fob says.

The result: A thief who successfully relays your key fob’s signal can open and enter the car, but cannot start the engine. With the car not starting, the attack fails. Most relay-attack thieves move on immediately — they work in volume and have no time for resistance.

The 87% Figure: Where It Comes From

TASSA (Tracking and Aftermarket Security Systems Association) commissioned an independent analysis of insurance claim data from major UK insurers between 2021 and 2024. The findings showed that vehicles fitted with a TASSA-certified CAN bus immobiliser experienced an 87% lower rate of successful relay-attack theft compared to identical vehicles without aftermarket immobilisers.

The figure is specific to relay attacks (the dominant theft method). It does not mean the vehicle is impossible to steal by other means, but it eliminates the most prevalent technique used against modern keyless vehicles.

What You Can Do Today

Tier 1 — Free/low cost:

• Park in a garage or well-lit, CCTV-covered area
• Keep key fobs in a Faraday cage/signal-blocking pouch at home
• Use a steering wheel lock (deterrent against opportunists)

Tier 2 — Effective:

• Aftermarket GPS tracker (helps recovery, does not prevent theft)
• Dash cam with active notifications

Tier 3 — Maximum prevention:

• TASSA-certified CAN bus immobiliser (CarGuard or Ghost 2) — prevents relay attacks, OBD key cloning, and signal amplification theft
• Consider combining with a GPS tracker for recovery capability
