Which Device to Add 2026 Nissan Qashqai Smart Key?

Problem:

Tried to add a smart key to a 2026 Nissan Qashqai J12 with Lonsdor K518 Pro. I connected the 40 pin bcm cable and communication failed. Also tried xhorse key tool plus and device did not connect. Did anyone had luck adding a key to this model?

Here is the clue.

It’s got updated security in 2026. Lonsdor, Xhorse, Autel all cannot do it.

Use dealer tool (Nissan Consult).

Or copy an NCF29Ax smart key using Keydiy KD-X4/NXP killer etc. But the cloning method carries a risk of losing synchronization.
