Total Vehicle Security Against Relay Attacks and Key Cloning

Car theft in the UK has evolved. Thieves no longer need your keys in hand — relay attacks and key cloning let criminals steal a modern car in under a minute without ever touching your key fob. If you’re a car owner, van fleet manager, or work in agriculture or plant machinery, it’s time to rethink what “vehicle security” really means.

At Safe and Sound Mobile, we install the Meta Trak S5 Deadlock — one of the most advanced, insurance-approved vehicle security systems on the market. Here’s everything you need to know about how it works and why it might be the single best investment you make for your vehicle this year.

What Is the Meta Trak S5 Deadlock?

The Meta Trak S5 Deadlock is a total vehicle security system that combines three layers of protection in one device:

Advanced engine immobilisation
Next-generation GPS tracking
24/7 control room monitoring

All of it is managed through a simple, intuitive smartphone app, giving you full control and visibility over your vehicle — whether it’s a family car, a high-value sports car, a van, a tractor, or construction plant equipment.

No ID Tag, No Start

At the heart of the S5 Deadlock is a straightforward but powerful principle: no ID tag, no start.

The Starter Immobiliser arms automatically when your engine is switched off and disarms only when your unique ID Tag is presented. This means that even if a thief manages to get into your vehicle, they can’t drive it away without your personal tag.

Lock Down From the App — Anytime, Anywhere

Want an extra layer of control when your vehicle is parked overnight, left at the airport, or sitting on a work site? With Deadlock Immobilisation, you can remotely lock your vehicle down straight from your phone. Once activated, the vehicle cannot be started — even with the correct ID Tag.

This is a genuine game-changer for fleet operators, plant hire companies, and anyone storing high-value vehicles for extended periods.

Built to Beat Relay Attacks and Key Cloning

Relay attack theft (where criminals amplify your key fob’s signal from inside your house to unlock and start your car outside) has become one of the most common forms of vehicle theft in the UK. The S5 Deadlock is specifically engineered to defend against relay attacks and key cloning, closing the very loophole modern thieves exploit.

For an extra layer of defence, the system also offers optional OBD Port Protection, immobilising the OBD port itself via the smartphone app to prevent key cloning through diagnostic port hacking — a growing method used by organised vehicle theft gangs.

Always Connected: What the App Gives You

The Meta Trak smartphone app keeps you connected to your vehicle wherever you are, with a full suite of monitoring features:

24/7 control room monitoring — professional oversight around the clock
ID tags — personalised, secure driver authorisation
Live tracking — know exactly where your vehicle is in real time
Unauthorised movement alerts — instant notification if your vehicle moves without authorisation
Low battery alerts — stay ahead of maintenance issues
Journey history — a full log of everywhere your vehicle has been
Multi-vehicle tracking — manage an entire fleet from one app
Auto immobilisation — automatic security the moment the engine stops
Deadlock immobilisation — full remote lockdown on demand

S5 Deadlock Plus: Extra Protection for Your Alarm

For vehicles already fitted with a factory or aftermarket alarm, S5 Deadlock Plus integrates directly with it, sending you instant notifications the moment your alarm is triggered — so you’re never the last to know if something’s wrong.

Covert Installation, Minimal Maintenance

One of the standout features of the S5 Deadlock is its discretion. Developed with the latest technology, it’s designed to be installed more covertly than ever, making it extremely difficult for thieves to detect or locate. It also boasts incredibly low battery drain and is fully waterproof, so it performs reliably in all conditions, year-round, without constant upkeep.

Thatcham-Approved: Category S5 Certified

Security claims mean little without independent verification. The Meta Trak S5 Deadlock is developed with — and certified by — the Thatcham Research Security Centre, meeting the strictest insurance criteria available: Category S5.

For vehicle owners, this isn’t just peace of mind — it can also translate into real savings on comprehensive insurance premiums, particularly for higher-risk or high-value vehicles.

Who Is It For?

The versatility of the S5 Deadlock makes it suitable for a huge range of vehicles and industries, including:

Performance and luxury cars — a common target for relay attack theft
Vans and commercial fleets — protect multiple vehicles from one dashboard
Agricultural machinery — tractors and farm vehicles are increasingly targeted by organised theft
Construction plant equipment — excavators and diggers left on unattended sites
Caravans and motorhomes — high-value assets often parked for long periods unsupervised
