Wikipedia:Featured picture candidates/Pin tumbler locks

Without a key in the lock, the driver pins (blue) are pushed downwards, preventing the plug (yellow) from rotating.
When an incorrect key is inserted into the lock, the key pins (red) and driver pins (blue) do not align with the shear line; therefore, it does not allow the plug (yellow) to rotate.
When the correct key is inserted, the gaps between the key pins (red) and driver pins (blue) align with the edge of the plug (yellow).
With the gaps between the pins aligned with the shear line, the plug (yellow) can rotate freely.
Reason
I feel that this image shows how pin tumbler locks in a very easy-to-understand way. I am proposing these images as a {{FeaturedPictureSet}}.
