*WARNING THIS IS LONG. *
I am somewhat new to picking locks. However, I have read quite a bit of material on the subject and have picked many locks (mostly pin tumbler locks and one or two wafer tumbler locks). I have read a lot so that why it makes me feel I should know the answers to my question but I don't so hopefully someone can help me. My first question is what is the name of the part of the lock the actually goes into the wall. (the part you are retracting to allow the door open). My other questions refer to this (and I will call it "X") how the lock responds to picking so hopefully you are up to speed with me. What is happening in a lock that when you pick it:
1) Only the "X" is slide back but the door knob or handle still won't turn.
2) You turn the knob to retract the "X" but afterwards the lock is still locked.
3) You turn the knob to retract the "X" but this time the door stays unlocked.
4)Why does the entire plug come out sometimes
5)Is it possible to pick a lock so the next time you try and pick the lock it becomes harder to pick or impossible to pick even though a key still works?
The only reason I asked the last question is the very very first lock i picked was pad lock and after i got it once i kept doing it to get faster and faster and I picked it like 100 times or so but then i couldn't pick it anymore because the pin would get pushed in and i tried everything i knew at the time, and still couldn't get it thought the key would still work. (I only actually picked each pin back then instead of raking or tapping). Also this happend to me recently, on a door i picked it like six times or so (not back to back, each time under 40 seconds with a rake pick) but one time when i went i could do it anymore. But then finally i got it by tapping/raking/picking but it was very difficult.
Thank you for anyone who spent the time to read this. I just want to more about why things happen in my hobby.
