What You Get from the SX-Tool Download

Your SX-Tool Download is the JET Master installer: a Windows application that communicates with DoIP-based JLR vehicles (MY2017–2025) over a standard ENET cable and performs diagnostics, ECU flashing, CCF editing, key programming and retrofit coding — most of it fully offline, without Pathfinder subscriptions or expensive proprietary hardware.

Demo vs Master License

We offer a free demo download so you can verify connectivity and explore the interface on your own vehicle before spending anything. The demo license is locked to one VIN and valid for 72 hours with full functions enabled. The JET Master annual license lifts the VIN and time limits for professional daily use.

Download and Installation Guide

Getting started takes under an hour on a suitable laptop. Prepare a Windows 10/11 machine, run the installer delivered with your license or demo approval, activate with your license credentials, then connect your ENET cable and launch. Detailed documentation lives at kb.sx-tool.com.

1. Prepare your system — Windows 10/11, stable internet, compatible JLR ENET cable
2. Download — use the installer link delivered with your license or demo
3. Install — run the setup with administrator rights
4. Activate — enter the license details from your email
5. Connect — ENET cable from laptop Ethernet port to the vehicle OBD port
6. Launch — the software detects the VIN automatically

Who This Tool Is For

JET Master serves specialist workshops, locksmiths facing All Keys Lost, independent technicians, electronics repairers who virginise used modules, and hands-on enthusiasts. Mostly coding rather than module replacement? Compare editions in the JET Master vs JET Pro guide before you buy.

Frequently Asked Questions

What is the difference between JET Master and Pathfinder? Pathfinder is the official dealer system — online-dependent, subscription priced, locked to proprietary VCIs. JET Master performs most of the same coding and programming offline over an affordable ENET cable. For the very latest models, some functions still need a TOPIx Cloud session.

What hardware do I need? A Windows laptop and a quality JLR ENET cable. If you want one interface for SX-Tool, SX-CAN, SDD and TOPIx Cloud together, we recommend the SX-Tool JLR diagnostic interface.

Can JET Master handle All Keys Lost? Yes — the full license supports All Keys Lost on DoIP-supported models by communicating with the vehicle security modules. If you are not confident working in-car, our JLR remote repair sessions pair the license with a technician.

Is the demo version limited? No — the demo runs with full functionality, locked to one VIN for 72 hours. Claim it through the free demo program.

Can I transfer the license to another computer? Licenses are tied to one PC; official licenses can be switched if your laptop is replaced, damaged or reinstalled — contact us to apply the switch. Demo licenses cannot be transferred. Details: license key.
