Hello, when changing tyres from summer to winter bikes I ripped off the anti-theft screw. The local car dealer then tried it with a tool, whose name I don’t know now – probably the best thing is “outside-driver”. Only on these screws outside a rotating ring is installed, which prevents the use of this tool. He still meant I should have hit the screw with a sling before the release. I didn’t have that. But I don’t know if it would have worked otherwise either. The stupid thing about it is that the key is also over, of course, because the “bart” of the screw plugs bomb-proof inside. For a few tips – if there are any – I would be grateful. Otherwise I have to put the car in a workshop, which welds nuts on the remaining locks then to solve them. You can’t guarantee that the rims are not screwed. Greet Martin
