    Hello, the problem is the hard unlocking of the steering wheel, the key jams in the zero position and it is hard to turn it. In addition, instead of locking in the extreme positions, the steering wheel locks in everyone.
    I think the problem lies in the worn ignition switch, although I don't like locking it in every position. There are whole sets with the bsi module available on the website, but I have a question, is it not enough to buy the key switch alone and then simply replace the key bayonet? Because it can be removed from this plastic. Is the transponder placed in this electric board in the remote control?
    Second question, two cables come to the ignition (apart from the ankle). I read that it is the power to the solenoid, but what is the solenoid? Or is it something from the steering wheel lock? It seemed to me that the lock is purely mechanical.

    You have a key or pawls in the ignition mechanism. The simplest and cheapest option is to drive to a workshop that makes keys and regenerates the ignition, where they match (fill in or replace) the key latches. Thus, you will not have to replace the door lock.
    You have a transponder in the key (such a small colored cube - which can be transferred to a new key). At eventual disassembly, watch out for the NATS receiver antenna loop that surrounds the base of the ignition switch (these two wires are from the immo receiver). When replacing the ignition switch, you would have to buy the entire starter kit (including immobilizer module and engine control unit), possibly reprogram the transponder.

    Of course, regeneration is the best option, but the owner wants to replace the entire ignition switch, because he thinks that regeneration will be not much cheaper than buying a second one. The door locks are covered with end caps, so all opening is done from the remote control.
    I mean that:

    the bayonet can be unscrewed and removed, and now if I bought a key switch and moved the bayonet to an old remote control, am I right that the transponder will remain in the remote control and you will not have to replace the immo module etc.?

    As for the antenna, it is unscrewed from the ignition switch without any problems, I mean these two wires:

    I have no idea what they are from, but don't they have something to do with the steering lock?

    Isn't it a Micra with a keyless system? In K12 a keyless system was used with such a patent for childproofing. Next to the knob / ignition was a small button that had to be pressed simultaneously while turning to start (and depressing the brake pedal). After removing this knob, there is a normal ignition that can be activated with the key (tip hidden in the remote control). In this system, blocking in any position after switching off the ignition is normal - this is how it should be. If the lock does not release, there may be something with the lock actuator or its actuation (or someone tried to force it on). Under the door covers there are also ordinary locks (if the remote control fails).
    From the statements I conclude that you are not the owner. Of course, another traditional solution is possible in this model.

    This is the correct behavior of the steering lock in every car, it locks in the same position as every full turn.

    @ robin161

    No, it's just a key, the one in the picture. And it seems to me that the lock here is mechanical, I just turn the key to zero and the lock pops out.

    @milejow

    My point is that after removing the key turn the steering wheel a small angle and it is already locking, which seems to me natural behavior, but according to the owner before it only locked at the maximum left or right turn. But if these cables are only from this picket, then the lock is independent, i.e. something dims this owner.

    And how about this immo? Because the allegro is available set ignition + key, I would buy, flipped the arrowheads, old transponder with a new arrowhead and should play without programming, do I combine?

    Replaced ignition, a new groove transferred to the old pilot, the car starts and drives.

Topic summary

The discussion revolves around steering wheel unlocking issues and ignition switch replacement for the Nissan Micra K12. The main problem involves difficulty in unlocking the steering wheel, with the key jamming in the zero position and the steering locking in various positions instead of just the extremes. Users suggest that the issue may stem from a worn ignition switch, with some recommending key regeneration as a cost-effective solution. There are inquiries about the transponder's location and the possibility of replacing just the ignition switch while retaining the old key's transponder. Clarifications are made regarding the mechanical nature of the steering lock and the function of certain cables related to the ignition system. A follow-up confirms successful ignition replacement and transponder transfer, allowing the vehicle to start and operate normally.
