Abstract
This Door Key Retention Security System guarantees that a key used to enable operation of a powered door is retained or locked in the invention until the door is, once again, closed. Thus, it requires a person who has authorized access to the key to insert the key and properly turn it in order for a door to be opened. Then, while the door is open, the key is locked in the mechanism and cannot be removed. When the need for the door to be open is ended, the door can be closed and the key removed.
