I'm a beginner and I purchased a Kwikset lock to practice with. After trying to pick the lock a while it became impossible to unlock the lock even with the key. I discovered that only the second from the back pin hole impeded the cylinder from turning. When I left the second from the back pin hole pinless the key worked and I was able to pick the lock.
After I picked the Kwikset lock many times I attempted to pick my dorm room lock. I managed to pick the lock a few times but somehow I damaged the lock and now my key doesn't fit into the lock.
Does any one have any ideas on what I'm doing that causes my locks to break? I use a pick that's not perfectly smooth. Is that a problem?
Also does any one have any ideas about how to fix my dorm room lock that the key will not fit into?
