I' ve came up with a fix if your key is already locked.
I couldn't remove the tumbler lock, which prevented me from pushing the pin that allows removing of the ignition switch.
I've bent the clamp with pliers, to get it off, then I've cut the black tube with 12V mini angle grinder, so that I could move the ignition switch a bit without pushing in the pin. Not removing the tumbler lock also made it impossible to take it out completely, but the point was to move it to the point where the tab that covers the pin is uncovered.
Finally i dived under the wheel and hit it with a screwdriver and a hammer. It worked and i didn't have to tear it down completely.
