I tried to make the "special tool" use some paper clips, and when i inserted it into the holes and use a pair of pliers to turn the tumber counterclockwise, one of the paperclips broke inside the hole!

So am i screwed with one of the paperclips stuck in the hole?

I will try to do it again, but if i have the paper clips in, do i turn the key and tumbler counterclockwise or just pull it straight out?

Many thanks in advance...
