This morning our leaf does not turn on.
If we enter the leaf without the i-key it says Key not detected.
If we enter the leaf with the key it says I-key system fault.

Any suggestion?

PS We tested both i-keys.
PPS It always happens on saturday!

Did you try replacing the battery? You also didn't mention if it would start with the "dead key battery" procedure (see manual). Either way, it would indicate a dead (key) battery.

i am assuming you used both FOBs to no avail?

well, being able to lock or unlock car means 2 things

1) your FOB battery is fine
2) all doors are shut (car wont respond if a door is open)

i think, next option is disconnect 12 volt battery, then open and shut all doors, reconnect battery and try again.

It happens with both FOBs.
I disconnected the 12 volt battery, opened the door with the key (the true one, not electric), closed the door, reconnected the 12 volt battery.
Same story.

The Nissan customer service suggested to bridge the 12 volt battery with a booster battery to be sure it is not a battery low voltage problem.
Same story.

They suggest not to recharge the 12 volt battery and to call the emergency truck (SOB).

PS Carwings says the main battery is charged to 75%. Maybe I can even charge it!

Paolo, what happened when you tried this?

I understand the "dead key battery" procedure is as follow.
1. Push the P (Park) position switch on the selector lever.
2. Firmly apply the foot brake.
3. Touch the power switch with the Intelligent Key as illustrated. (A chime will sound.)
4. Push the power switch while depressing the brake pedal within 10 seconds after the chime sounds. The power switch position changes to READY to drive mode.

I tried but when I touch (not push) the power switch with the intelligent key nothing happens.

Could it be as simple as a blown fuse?
