Nissan 16+32 Secure Gateway Adaptor Applicable to Sylphy Sentra (Models with B18 Chassis) For Autel

This is a special adapter/bypass cable used with automotive diagnostic and key-programming tools (like Autel scanners). It connects your tool directly to the Nissan Secure Gateway (SGW) system used in newer Nissan models (especially 2020 and newer Sylphy and Sentra with B18 chassis).

What It Does

✔️ Gateway Bypass – Allows your diagnostic/programming tool to communicate directly with the car’s systems without being blocked by the Secure Gateway.
✔️ Key Adding Without Password – With an appropriate Autel tool (eg, IM508, IM608), you can add a new key without needing the Nissan dealer PIN as long as at least one working key is present.
✔️ Enhanced Diagnostics & Programming – Enables advanced diagnostics, bi-directional controls , active tests, maintenance resets, live data, and some immobilizer functions that the SGW normally blocks.
✔️ Supports B18 Chassis Vehicles – Especially designed for Nissan Sylphy, Sentra, and some related models using the B18 platform (2020+, 8th generation).

Why It’s Useful

• Without this adapter, many Nissan SGW-equipped vehicles will reject diagnostic or key programming commands at the OBD2 port unless the tool has an authorization/password.

• With the adapter, tools like Autel can add keys and perform functions faster and more reliably on 2020+ models without needing dealer software updates or PIN codes (in supported cases).
