Nissan Security Gateway Access Opens to Independent Garages

Independent garages using compatible LAUNCH diagnostic equipment can now gain authorised access to Security Gateway-protected Nissan and Infiniti vehicles following the introduction of a new Nissan SGW unlocking licence.

LAUNCH UK & Ireland announced the new access on 1 October as vehicle manufacturers increasingly protect diagnostic functions behind digital security systems.

The development affects a growing number of Nissan vehicles seen by independent workshops, including popular models such as the Qashqai and Juke, alongside the Ariya and X-Trail.

Without the appropriate Security Gateway authorisation, technicians can find some diagnostic, service and coding functions restricted even when they have compatible diagnostic equipment.

For independent garages, it is another example of how repairing modern vehicles increasingly depends not only on having the right tools and technical knowledge, but also on having authorised digital access to the vehicle.

What is a Security Gateway?

Security Gateway technology is effectively a digital barrier between a vehicle’s diagnostic connection and its internal electronic systems.

Manufacturers have increasingly introduced these systems as vehicles have become more connected and software-dependent.

Their purpose is legitimate: preventing unauthorised access to safety-critical or security-sensitive vehicle systems and reducing the risk of malicious manipulation.

But they also change how independent technicians work.

Connecting a diagnostic tool to the vehicle’s OBD port does not necessarily mean a technician automatically has access to every function.

On a Security Gateway-protected vehicle, some functions may require authentication before the vehicle will accept commands from diagnostic equipment.

Depending on the manufacturer and vehicle, that can affect procedures such as coding, programming, service functions, actuator tests and other advanced diagnostic operations.

Nissan has used Security Gateway protection since 2019

According to LAUNCH UK & Ireland, Nissan began introducing Security Gateway protection on selected vehicles from around 2019.

The technology now affects a range of vehicles likely to be encountered by independent workshops, including the Qashqai, Juke, Ariya and X-Trail.

For garages, this becomes increasingly important as newer vehicles move out of manufacturer warranty periods and into the independent aftermarket.

A workshop may have technicians capable of diagnosing a fault and equipment capable of communicating with the vehicle, but still encounter restrictions if the necessary manufacturer security authorisation is not available.

New licence provides authorised Nissan access

LAUNCH’s new Nissan SGW Unlocking Licence provides an authorised route through the gateway for workshops using supported X-431 diagnostic platforms.

The system also covers compatible Infiniti vehicles.

Garages purchase a digital 12-month licence and register it through the LAUNCH Security Gateway portal.

LAUNCH says approval and activation would normally take between one and two working days.

An active LAUNCH diagnostic software subscription is also required.

Once authorised, technicians can use compatible X-431 equipment to access protected functions rather than attempting to bypass the manufacturer’s security system.

That distinction is important.

Security Gateway access is not designed to circumvent vehicle security. It provides authenticated access allowing legitimate repairers to carry out authorised diagnostic and repair procedures.

More manufacturers are protecting diagnostic access

Nissan is far from alone in introducing this technology.

Security Gateway systems or equivalent manufacturer security controls are increasingly common across newer vehicles.

LAUNCH already provides Security Gateway support covering manufacturers including Volkswagen Group brands, Mercedes-Benz and Renault/Dacia, with different access arrangements applying depending on the manufacturer.

The direction of travel is therefore clear.

For workshops investing in diagnostic equipment, vehicle coverage alone is becoming only part of the equation.

Garages increasingly need to consider whether their diagnostic platform can also provide the authorised access required to perform functions on security-protected vehicles.

Why this matters for independent garages

The development comes at a particularly important time for Britain’s independent aftermarket.

Modern cars increasingly depend on software, electronic control units, online services and manufacturer-controlled information.

That means access to data and vehicle systems is becoming almost as important as access to physical replacement parts.

Recent research from LKQ Euro Car Parts illustrated the potential consequences, you can read more about this here

Its Plug In-Dex research found that nearly nine in ten independent garages surveyed had turned away or referred at least one EV or plug-in hybrid enquiry during the previous six months.

More than a quarter cited concerns about diagnostic access for newer EV brands as a factor discouraging further investment.

Security Gateway access is not exclusively an EV issue – protected diagnostic systems are fitted to petrol, diesel, hybrid and electric vehicles.

But both developments demonstrate the same wider challenge facing independent workshops: having the equipment to physically repair a vehicle does not necessarily guarantee access to the digital systems needed to complete the job.

Security Gateway and SERMI are not the same thing

The increasing use of Security Gateways also comes as Britain’s independent aftermarket adapts to the introduction of SERMI.

The Security-related Repair and Maintenance Information scheme went live in Great Britain on 1 April 2026.

SERMI provides approved independent repair businesses and technicians with an authenticated route to security-related vehicle information from participating manufacturers.

That can include work involving keys, immobilisers and other anti-theft systems.

However, SERMI and Security Gateway access should not be treated as interchangeable.

A Security Gateway controls communication with protected electronic systems within a vehicle and may restrict diagnostic and service functions.

SERMI provides a framework for verifying legitimate businesses and technicians seeking access to security-related repair and maintenance information.

Depending on the vehicle and the work being undertaken, a garage may therefore encounter different manufacturer security and authentication requirements.

Diagnostic access is becoming a competitive issue

The wider concern for the independent sector is what happens when access becomes too difficult, expensive or fragmented.

If an independent workshop cannot complete a job because it lacks the necessary digital authorisation, the vehicle may ultimately have to be referred elsewhere or returned to a franchised dealer.

That potentially costs the garage revenue while reducing choice for the motorist.

It also makes investment decisions more complicated.

A garage considering new diagnostic equipment now needs to look beyond how many vehicle brands appear on the specification sheet.

It increasingly needs to ask what level of functionality is available on newer vehicles, how manufacturer authentication is handled, whether additional licences are required and what ongoing subscriptions will cost.

Those considerations are likely to become increasingly important as Security Gateway-equipped vehicles make up a larger proportion of the cars entering independent workshops.

Keeping modern vehicle repairs in the independent aftermarket

Jon Woolley, Sales & Marketing Director at LAUNCH UK & Ireland, said Security Gateway technology was rapidly becoming standard across newer vehicles and that authorised access was becoming essential for independent workshops.

LAUNCH says adding Nissan to its coverage should enable customers to diagnose and service a wider range of vehicles without unnecessary delays or having to turn work away.

For the independent aftermarket, however, the significance extends beyond one diagnostic-equipment manufacturer.

Vehicle repair is rapidly becoming a combination of mechanical skill, diagnostic capability, technical information and authenticated digital access.

Independent garages have traditionally competed by investing in technicians, equipment and expertise.

Increasingly, maintaining that competitiveness will also depend on whether they can obtain legitimate and commercially viable access to the protected electronic systems inside the vehicles arriving in their workshops.
