This video demonstrates using the Lock50 HW04-C tool to duplicate a key for a 2016 Land Rover Discovery Sport L550. It shows identifying the existing key, performing a network integrity test, and reviewing module information. Crucially, the tool successfully clears a Diagnostic Trouble Code in the GWM (Gateway Module). The main feature is duplicating a new key for a locked RFA module, bypassing the usual 'add spare key' limitations and successfully programming a cloneable JLR key.

The video opens with the Lock50 software interface, demonstrating key identification. It shows successful identification of a Mitag Security Transponder key. A network integrity test is performed, connecting to the vehicle via an OBDII cable, and processing various modules like BCM, GWM, IPC, RFA. Vehicle information for a 2016 Land Rover Discovery Sport L550 is displayed. The software then accesses the GWM module, reads and successfully clears a Diagnostic Trouble Code related to software incompatibility. Next, in "Special Tools," the "Key Duplicator" function is selected. An information pop-up confirms the function is for locked RFA modules and requires a special cloneable JLR key. The tool collects data from the vehicle, processes the RFA module, and displays key copy options. It shows 2 keys are currently learned and 1 key is prepared. The software prompts to place the next key on the reader, then proceeds to read and write the key data. Finally, it confirms that 2 keys have been successfully programmed into the vehicle.

This video demonstrates the Lock50 JLR Key Tool (v1.4.3.0) being used to program keys for a 2023 Land Rover Discovery Sport (L550 model). The process involves duplicating an existing key and adding a third OEM key, even with a locked RFA module. The tool performs RFA unlocking and enables emergency start functionality. The entire job is shown to be completed quickly, around 5 minutes, without needing to replace any modules like the RFA or BCM.

The video displays the Lock50 JLR Key Tool interface. It shows the software loading, connecting to the vehicle, and performing a 'Network Integrity Test' to identify modules like RFA, BCM, GWM, IPC, DDM, DRDM, PCM, TCU, and VIM. The tool then accesses the 'Special Tools' menu to use 'Key Duplicator.' After selecting the option, it prompts to place the key on the reader. It reads the first key (Position 1), then prompts to make more keys. It reads and writes the second key (Position 2). Next, it navigates to 'PEPS System > Utilities > Add Additional Passive Key.' It identifies the third OEM key and proceeds to process the RFA and BCM, successfully adding the third key (Position 3). The final screen confirms three programmed keys.
