Nitro Immobiliser & 4G S7 Tracker | Thatcham Approved

Protect your vehicle with a hidden immobiliser and Thatcham approved tracking, professionally fitted by Safe and Sound. The Nitro Immobiliser and 4G Insurance Approved S7 Tracker package combines theft prevention with rapid recovery, backed by our 30 years of vehicle security fitting experience.

Why Fit an Immobiliser and Tracker Together?

Modern vehicle theft rarely involves a broken window. Key cloning, relay attacks and OBD port theft mean criminals can be driving away in under a minute, without ever touching your keys. A single security layer is no longer enough.

This package tackles the problem from both ends. The Nitro Immobiliser stops the vehicle being started in the first place, while the S7 tracker makes sure that if the worst does happen, a dedicated UK monitoring team is already working to get your vehicle back.

Nitro Immobiliser: No PIN, No Start

The Nitro works on a simple principle: 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 to spot, no extra fob to carry and no radio signal for thieves to intercept.

• Blocks the engine from starting even if thieves have a cloned or stolen key
• Defeats relay attacks on keyless entry vehicles
• Integrates with the vehicle’s CAN bus for clean, reliable operation
• Re-arms automatically every time you switch off, so protection is never forgotten
• Valet and service mode lets garages or parking staff drive the vehicle without learning your PIN

S7 Tracker: Thatcham Approved, Monitored 24/7

The 4G S7 tracker holds Thatcham Security Certification TSC 527, the recognised UK insurance standard for monitored stolen vehicle tracking. Many insurers ask for exactly this level of protection on higher value vehicles, and fitting one may help with your premium.

Your vehicle’s location is monitored 24 hours a day, 365 days a year by a dedicated UK based team. If the vehicle moves without the ignition on, such as being lifted onto a flatbed, an alert is raised immediately and the monitoring centre liaises directly with the police to recover it. You can also follow your vehicle live through the free Android and Apple app, set geofence alerts and review journey history. A multi-network SIM roams across networks for the strongest signal and continues working outside the UK at no extra charge. Professionally monitored trackers of this kind sit at the heart of the UK’s aftermarket security industry, alongside standards bodies such as TASSA.

Professional Immobiliser Fitting by Safe and Sound

An immobiliser is only as good as its installation. A poorly hidden unit or an untidy wiring job hands thieves the clues they need. With over 30 years of vehicle security fitting behind us, Safe and Sound installs the Nitro Immobiliser and S7 tracker discreetly and correctly, with every component concealed and all wiring integrated cleanly into your vehicle.

Once the fitting is complete, we walk you through setting your PIN, using valet mode and getting the tracking app configured, so you leave knowing exactly how your new security works.
