Forgive me if this question is too noob but I have just discover lockpicking and english is not my native language so I lack the technical vocabulary necessary to get the most of my google-fu skills. Maybe this have been asked and answered before in this forum but, again, I dont know how to start searching for this.
I've stumble upon the following keys/locks which I'm not able to identify. So, how are they called? How do they work? (Any video or computer animation showing the internals?) How to lockpick them?
1. This one seems like a mix of internal cut and dimple.

2. This one is similar to an internal cut but with multiple thin grooves insted of one wide groove. Resembles a digital circuit.

3.Similar to the previous one

Thank you very much!
