Kia Ceed (JD) SW Switching knob accessories

Moin, since Kia for the original switch knob, which is scraped off, 156 Euro called up I wanted to ask if someone has ever got a switch knob from the accessories so screwed up, the 1) The switch knob is so fixed that it no longer turns 2) then the reverse gear can be inserted. and 3) How does Kia get that, take the for the last thread passage a shot screw securing varnish, so that he does not turn any more?
