Ah ok its hard to know how much someone knows sometimes lol
Hmm, does the pin come along the bottom of the keyway and have a point on the end and the key has a hole down the edge?
Or is it a pin in the side near the bottom of the keyway?
Have you tried pressing it in until the plug turns a bit and then try picking the lock?
There is a guide on site on how to put pictures up but basically open an account at photobucket.com (its free) and then upload your pictures to that, once youve done that click on the IMG link and it will copy it, then in your post click your right mouse button and select paste,
Make sure you make your album private so only the linked to picture can be seen
Where in the world are you?
