I've picked a mila lock on a patio door, the pick got stuck, i've now got it out. But when you look into the key way you can see the first pin at the top, but at the bottom of the keyway in the front it looks like there is a pin obstructing the keyway. I can't put the key back in to lock it from the inside, which isn't a problem as i can lock it from outside. What i want to know is why does this happen, when i pick these locks
