If these are the common bank variety they have 6 or 7 pins and are known to use very deep cuts beside a very shallow cut. They do not commonly have security pins. They are often master-keyed so the bank only has to use one key to open all the customer night-drop bags. Codes are available for many. They are difficult to pick mainly because of the relatively small and restrictive keyway and the high-low pin combos. Have fun picking.
Nothing is foolproof to a talented fool. Wisdom is not just in determining how to do something, but also includes determining whether it should be done at all.
