Help, I have a double keyed deadbolt lock on my back door and it won't open. I have the key and when I turn it, it just clicks and doesn't move the bolt. It feels as though it is not even moving the bolt across anymore, like something has broken inside. I can turn the key which slides a plate and give me access to the two screws holding the lock to the door. My question is this: once I do this, will I be able to physically move the bolt out of it's female counterpart in the door frame?
