How To Stop Relay Theft & Vehicle Break-ins: The Ultimate Guide to UK Car Security

Vehicle Crime in the UK has Reached a Critical Point

Vehicle crime in the UK is no longer a low-level risk — it’s a fast-moving, tech-enabled industry. With over 100,000 vehicles stolen in a single year, a significant proportion now involve keyless relay attacks, where thieves exploit your key fob’s signal from inside your home in seconds.

Whether you’re parked in a city centre, at home, or on a quiet residential street, your vehicle faces two distinct threats: electronic signal theft and physical break-ins.

At Caseva, we specialise in closing both gaps. We combine military-grade Faraday technology from GoDark® with high-security physical storage systems and professional-grade metal cases — creating a complete vehicle security ecosystem for individuals and organisations who cannot afford compromise.


The Electronic Threat: How To Stop Relay Theft

Modern vehicle theft is often silent. Relay devices can capture your key’s signal from inside your home and transmit it to your car, allowing thieves to unlock and drive away in under a minute — sometimes under 30 seconds.

The most widely recommended countermeasure by security experts and UK police guidance is simple: block the signal completely.

GoDark® Faraday Bags — Military-Grade Signal Protection

Caseva is the authorised UK distributor for GoDark®, a Canadian manufacturer trusted by military, government, and law enforcement agencies worldwide.

Unlike generic pouches, GoDark® products are engineered for operational environments where failure is not an option.

  • Independent signal attenuation testing – up to 100 dB reduction across key frequencies (GPS, 4G/5G, WiFi, Bluetooth)
  • Military-standard construction – built to MIL-STD-188-125-2 EMP shielding principles
  • Three-layer shielding system – maximum protection against signal leakage
  • Durable build quality – 600D outer shell with RF-welded seams for long-term use

Used correctly, any GoDark® bag will fully isolate your key fob or device — eliminating the signal required for relay theft entirely.


The Physical Threat: Protecting Valuables from Break-Ins

Signal protection alone is not enough. If a thief gains physical access to your vehicle, laptops, documents, cameras, and other valuables are still at risk.

This is where Caseva’s physical security range comes in — designed to secure what Faraday protection cannot.

Caseva Car Lock Boxes & Vehicle Safes

Our metal car safes are engineered for professionals, collectors, and anyone transporting high-value or sensitive items.

  • High-strength construction – precision-engineered aluminium alloy
  • Advanced locking systems – including premium ABLOY® Protec security mechanisms
  • Vehicle anchoring options – security cords prevent removal during break-ins
  • Discreet storage design optionsreduces visibility and opportunistic theft risk

Built for real-world theft scenarios.

Caseva safes are designed to do one thing properly: stop opportunistic theft.
Combined with the tether system, they create a fixed, secure storage point inside your vehicle.

These are not basic storage boxes — they are professional-grade security solutions used in operational environments where asset protection is critical.

The Caseva Tether System

One of the most effective anti-theft features in our range is the Caseva tether system.

Anchoring prevents “grab-and-go” theft — even if the vehicle is breached

This sliding locking mechanism allows the safe to be physically anchored within the vehicle, preventing “grab-and-go” theft even if the vehicle is broken into.


A Complete Security System: Layered Protection

The most effective vehicle security strategy is not choosing between electronic or physical protection — it’s combining both.

  • Step 1: Store key fobs in a GoDark® Faraday bag to eliminate relay risk
  • Step 2: Secure laptops, documents, and valuables in a Caseva lock box
  • Step 3: Anchor the box using the tether system for physical theft resistance

This layered approach removes both major attack vectors: remote signal interception and opportunistic physical theft.


Real-World Use Cases

For Professionals

Solicitors, finance professionals, engineers, and remote workers rely on secure transport of sensitive data. Combining Faraday protection with locked physical storage supports stronger data security practices and helps align with GDPR expectations for handling confidential information.

For Collectors & High-Value Equipment Users

Cameras, tools, prototypes, and specialist equipment are frequent targets for opportunistic theft. A visible deterrent combined with locked, anchored storage significantly reduces risk during travel or site work.


Expert Vehicle Security Tips

  • Always block your key signal – store keys in a GoDark® Faraday bag when not in use
  • Never leave valuables visible – even empty bags can attract attention
  • Use anchored storage – prevent “lift-and-remove” theft with tethered lock boxes and backpacks
  • Choose secure parking where possible – lighting and visibility remain important deterrents

Why Caseva

Caseva is evolving into a dedicated UK leader in integrated vehicle security solutions — combining:

  • GoDark® military-grade Faraday technology (authorised UK distribution)
  • Disklabs professional data protection solutions
  • High-security vehicle lock boxes and tether systems engineered for real-world use

Rather than treating electronic and physical security separately, we design and supply systems that work together — protecting both your vehicle and everything inside it.


Secure Your Vehicle Today

Vehicle theft is evolving — your security should too. A modern defence requires more than alarms and steering locks. It requires signal isolation, physical containment, and layered protection.

Explore the Caseva range of GoDark® Faraday bags, Disklabs solutions, and high-security vehicle lock boxes to build a complete protection system for your vehicle and valuables.
