If you’ve ever had to work on a 2018+ Jaguar or Land Rover smart key, you know how stressful it can be. Dealing with KVM modules and expensive RFA replacements is enough to make any locksmith sweat.
But here is some exciting news: Both KEYDIY KD-X4 and CGDI K2 Smart Key Tool now support direct copying/cloning of 2018+ JLR NXP NCF29Ax smart keys! This means zero module disassembly and absolutely no risk to the car.
Let’s look at how both tools get the job done.
With KD-X4: Smooth & Reliable
KEYDIY has made this update highly compatible with NXP NCF29Ax smart keys (OEM keys and KD ZB series keys).
How to do it:
- Pop open the original key to get to the circuit board.
- Open the KD App and head to: Land Rover Smart Key Synchronization -> Land Rover -> Select by Type -> Disassemble to Copy Key -> Copy Smart Key.
- Follow the pinout diagram shown in the app.
💡 Quick Tip: You can either solder wires directly to the PCB, or desolder the NXP chip and place it on the specialized KD #13 NCF29Ax adapter.
- Read and save the data, then write it straight onto your new replacement key!
With CGDI K2: Precision & Customization
CGDI K2 cloning update for ID49 Hitag Pro smart keys is incredibly precise and even lets you manually edit Key IDs to make sure the car pairs flawlessly.
How to do it:
- First, read the original key’s status on your K2. Pop open the shell to reveal the green PCB.
- Next, open the Land Rover Smart Key Cloning menu in the K2 app to get your wiring layout.
- Now, solder CGDI K2 renew cable to the board, select NCF29A4 (350728 byte) Locked under the MCU Programmer menu, read the data, and save it.
- Finally, move your soldered wires to the blank key, write the saved file, and use the “Modify Key ID” feature if required.
Do a quick final read-check to verify the key is active!
