Get 4G GPS tracking and PIN-start theft protection in one professionally fitted package from Safe and Sound. The Nitro Immobiliser stops your vehicle being driven away, the included 4G GPS tracker tells you exactly where it is, and our 30 years of vehicle security fitting experience makes sure both stay hidden from prying eyes.
Two Layers of Security, One Straightforward Package
Vehicle thieves work fast. Key cloning and relay attacks can defeat factory security in seconds, which is why a second, hidden layer of protection makes such a difference. This package pairs the Nitro Immobiliser with a 4G GPS vehicle tracker at no extra cost, giving you theft prevention and location awareness together.
If someone tries to take your vehicle, the immobiliser keeps the engine dead. And because the tracker reports its position over 4G in real time, you are never left wondering where your vehicle is, whether it is parked outside or halfway across the country.
Nitro Immobiliser: No PIN, No Start
Before the engine will run, you enter a personal PIN sequence using buttons your vehicle already has, on the steering wheel or dashboard. There is no keypad on show, no extra fob to carry and no radio signal for thieves to detect.
- Blocks the engine even if thieves have a cloned or stolen key
- Defeats relay attacks and key cloning on keyless vehicles
- Re-arms automatically every time you switch off, so it is always working
- Invisible CAN bus installation with nothing for a thief to spot
- Starting your vehicle stays quick and simple once your PIN becomes habit
4G GPS Tracking You Can Check in Seconds
The included 4G GPS vehicle tracker puts your vehicle’s location in your pocket. Open the app and its position appears on the map within moments, ideal for checking on an overnight parking spot, a work van or a family car.
- Live GPS tracking in real time over fast 4G connectivity
- Geofence alerts warn you instantly if the vehicle enters or leaves an area you define
- Multi-network SIM roams automatically for the strongest available signal
- Carries on tracking outside the UK, so trips abroad stay covered
- Suits families and businesses keeping an eye on several drivers

Which Package Is Right for You?
The 4G GPS tracker in this package is self-monitored: you watch your own vehicle through the app, without ongoing monitoring centre fees. If your insurer requires a certified system tested by Thatcham or verified under the TASSA scheme, ask Safe and Sound about our insurance approved tracker packages instead. For most drivers who simply want serious, affordable protection, this bundle is the sensible place to start.
Fitted the Right Way by Safe and Sound
A security system that a thief can find is a security system that can be beaten. Safe and Sound has been fitting vehicle security for over 30 years, and that experience shows in the details: the immobiliser integrated invisibly into your vehicle’s electronics, the tracker tucked where nobody would look, and every wire routed as tidily as a factory loom.
Before you leave, we show you how to set your PIN, use the tracking app and set up your geofence alerts, so the whole system feels second nature from day one.
