Impressioning tool for picking locks

Well, James Bond might not have the patience for this tool, but the idea of inserting a piece of aluminium foil into a lock to open it makes the imagination run wild. Walking up to a locked door and inserting a tool that just magically opens the lock is what everyone sees in the movies, so I guess this is pretty close to being a movie type lock opening tool. A lock only has to open once to let in a thief, or worse, so it doesn’t really matter if the lock pick tool isnt designed to last for very many uses.

This lock is opened using a method locksmiths call impressioning. Impressioning a lock works because the pins inside the lock bind when they are not in the correct opening positions. When the pins in the lock are correctly lined up, as they would be with a key, they no longer bind and are happy to just sit in the correct position. Impressioning works on a wide variety of lock types from old fashioned lever locks, safe locks, Yale locks, Lockwood locks, and many high security locks.

The tool used in this video is for a specific type of lock cylinder. They are called dimple locks. They are not known for high security in the first place, so this tool is a bit of an overkill as an opening technique. It is more of a gimmick then a serious lock opening tool.

Dimple locks use a key that is flat on both sides and has dimples in the key which are a hole drilled into the key at the correct depth to match the lock pin size. There are only so many different hole sizes you can drill into a key like this which is why this lock impressioning technique works on this particular type of lock. There is not a great deal of difference in the height of the pins, so a piece of aluminium foil is all that is needed to set the depths.

These locks are generally not used in Brisbane, due to their low security and because they are rather simple to open. You do see these dimple locks on different types of devices such as steering wheel locks for cars, but generally not on house doors or anywhere that there is a need for more security.

I thought this was an interesting idea to share with people who are interested in knowing different ways to open a locked door. It might not be very practical, but it definitely has that James Bond appeal to it.
