concept for two key lock

[hzatorsk]

Okay... fair enough... SFGOON... I think we both made a good point.

I am not sure exactly when this push/pull/shift operation would take place. But care should be exercized that the shifting cannot be used without the key.

I don't know exactly how you'd prevent that.

I was thinking spring load the plug to push it forward, and to engage the second bible you'd have to push it back 5cm or so. You'd also have to use the second key to restore the plug to the original position.
