摘要

An anti-pick device for a lock is described in which a housing is mounted over the key slot entrance in the lock and a key holder is mounted slidably in the housing for movement along a path aligned with the key slot. A recess is provided in the key holder extending transversely of the path of movement of the key holder for receiving a key and supporting the key in alignment with the key slot.
