Keydiy KD-X4 has recently updated the NXP NCF29Ax smart key copying function. Here, we will demonstrate how to copy a 2021 Haval H6 smart key using KD-X4.

 

Chip type: ID47

Original key type: NXP29A1

Tools used:

Keydiy KD-X4 key programmer

Keydiy NCF29xx adapter (#13 adapter)

Keydiy KD C29A71 smart key

Original smart key

Write smart and proximity sensor to the new KD key.

Connect the KD C29A71 key circuit board with KD-X4 using the 6 pin programming cable.

Generate proximity key successfully.

Then install the KD circuit board with key shell.

Reinstall the key chip back onto the original key circuit board. Install the original key shell.
