Nissan key not turning

B2590
Security Theft / No Start

Hello DN, I have a 06 Nissan Note supposedly the seem as the Nissan cube to go to tomorrow and diagnosis the Steering Lock system where the key would not turn. I have been at this vehicle before last time I checked the battery all the fuses confirmed the key would not turn, scanned it, and got a code b2590 out of the BCM. From what I gathered on the code B2590 is the ID verification between the BCM and intelligent key unit is NO GOOD not saying this code is the cause but this is the only code I got. OK now this is what I saw when I was at the vehicle,this is not a push start there is only the mechanical key there is no remote with the key I was told it was lost a while now. When I place the key inside the key cylinder and press on the key a little red KEY light comes on on the dashboard facing me and the anti-theft light on top of the dashboard goes out. I have tested the key with my zed bull key tester and it checked out ok also checked the key antenna module at the key cylinder with my LED light ring and the light lights up when I put the key in. Now I have looked at what Nissan says to look at when the key won’t turn and it says to monitor voltage readings at the four wire connector to see a waveform with a voltage between If I remember correctly ZERO AND SIX VOLTS. Now, this is the kicker, while back probing one of the wires at that connector the steering lock magically released the vehicle started and run and kept releasing for about two days and then just up and quiet. And to be honest I can’t say I ever saw any waveforms at this connector I was only seeing 4.9 volts. But I will say I was using my power probe maestro with the waveform viewer on and I did see waveforms when I used it to test the key antenna module signals, you guys are the greatest and all help would be welcomed thanks. Sorry, the connector I was referring to was the one on top of the steering lock cylinder, when it did release I was on a gray-colored wire.

Just wondering am I asking a forbidden question or is it maybe that no one here works on these vehicles, I just want to know if I am doing something wrong and what should I be asking?

As far as I know, if it has a mechanical key, the lock cylinder and/or the key are the only things that can stop it from rotating. Besides pressure from the steering lock(wiggling the steering wheel back and forth as you try to turn it to reduce pressure)

The solenoid (if so equipped - iirc, the Note is a bare-bones vehicle), will only stop you from removing the key in the pre-2011 vehicles. So, if it is not turning at all, its the lock cylinder and its interface to the column lock, not something electrical (barring the ignition switch itself disintegrating, which I've never seen in a Nissan).

I totally understand where your coming from , my only question is I wonder why it happened to release when I was probing one of the wires on the steering lock connector or It my have been by chance, seeing that I did the seem thing again and this time it did not release . So it seems the customer needs a lock cylinder l will inform them and report back on this vehicle.

Just to be on the safe side, I went to a junkyard and removed the steering lock cylinder from a 06 Nissan note just to be sure before I told the customer to go ahead and buy a new one… and guess what with the correct key the lock cylinder still does not rotate so I made a call to a Nissan dealer tech and he says it definitely needs electrical inputs.

I cannot find service information for that vehicle, I tried a couple 2006 nissans and the wiring diagrams do not show any electrical inputs to the ignition lock cylinder. I'd love to help you but I don't have any service information to give you a direction.

First of all, the first year for the Versa/Note in NA is 2007. There is a shift-lock solenoid, but no ignition lock solenoid. The electrical inputs for the key are just a key-in switch.

After doing some cross-reference checking between the code I got at the vehicle the first time I was there which was code B2590 this code in Nissan service information is the same meaning as P1615. Concerning the key switch, on the wire diagrams from Nissan, I can see a key lock solenoid, a key switch relay, and an ignition knob switch relay so wouldn’t you say there must be some electrical…
