Unlocking Security Gateways with Autel Scanners: Fast, Safe Diagnostics

With the rapid development of automotive electronic safety technology, security gateway (SGW) has become a standard feature of many new cars, which has not only improved vehicle network security, but also brought new technical challenges to the maintenance industry.

This article will analyze in detail the necessity of SGW unlocking, and guide you on how to efficiently complete the unlocking operation through Autel diagnostic scanners. At the same time, it provides practical solutions for common faults to help maintenance technicians seize technical opportunities.

Why do I need to unlock my security gateway?

As a "firewall" for the vehicle's electronic systems, the Security Gateway (SGW) will limit access to key control modules to prevent illegal tampering or malicious operations. However, this also means that conventional diagnostic equipment will not be able to perform the following key repair functions:

• Active testing(such as actuator and sensor activation)
• Service reset(maintenance light reset, mileage correction)
• ECU programming(software refresh, code matching)
• Module configuration(parameter adjustment, function adaptation)

With Autel's SGW Unlock feature, you can safely and legally access these features, ensuring that routine repairs and in-depth diagnostics proceed smoothly.

Which models are equipped with a Security Gateway (SGW)?

At present, new models launched by mainstream brands after 2018 (especially European, American and domestic high-end models) are generally equipped with security gateway modules, including:

• German: Mercedes-Benz, BMW, Audi (some models have been applied in advance in 2016)
• American: Ford, GM (such as Buick GL8 after 2020)
• New energy: Tesla, BYD e-platform 3.0, Weilai ET7, etc.

Note: Some models of Japanese and Korean models (such as Toyota, Honda, Hyundai) will not be gradually equipped until after 2020, and the protocol is relatively open.
