You can get the pin out by taking off all the keychain except the little loop on the pin, put a paperclip through the loop and pull really hard with pliers. It helps to put on gloves sometimes. OR, heat up a soldering gun, put the tip in the loop and pull, after a few seconds it will come out. Do this quickly so that you don't melt the figures head. I hope this helps. Getting keychains is a cheaper way to get figures than getting them in sets, if you don't mind the little hole in the top of the head.

If it works let me know. I've never tried the soldering gun method before, you can see it done on YouTube I think.
