Scania 124l 2002: Ignition Switch Replacement - How to Remove Pin & Install New Unit

Hello everyone.
Ignition switch in Scania 124l 2002. It does not reflect the key when igniting, the starter keeps spinning and the engine works, when I withdraw the key, the starter stops spinning. So I decided to replace the ignition with a new one, but to my surprise it is not that simple. It seems that the ignition switch is not screwed on, but it is secured with a pin and I do not know how to remove it and install a new one. So I am asking you for advice and thank you in advance for valuable tips.
Best regards.

Hello

Only this lower electric element of the ignition switch is replaced !!! Under the paint there are small screws for a flat screwdriver, unscrew them and replace the element.

Thank you, shaman108, I replaced the lower cube and the ignition is working.


Best regards.
