Abstract
A protective cover for a keyway disposed on an end surface of a lock is provided. A housing is adapted to be assembled over the lock end surface. The housing includes an opening that surrounds the keyway. At least one door is disposed in the housing opening. The door includes an edge for aligning with the keyway in a key insertion position. When a key is pressed against the door, the door moves away from the keyway, providing a key opening in the housing opening for insertion of the key into the keyway. At least one door biasing member engages the door and biases the edge of the door toward the keyway. The door is mounted on a pivot member disposed in the housing opening such that the pivot member and door pivot within the opening when the key is inserted into the keyway and turned in the lock. At least one pivot biasing member engages the pivot member to hold the edge of the door in alignment with the keyway when the keyway is in the key insertion position.
