Abstract
A locked/unlocked indicator for a key that shows whether a person has locked a door lock or any type of lock. The indicator has a base member having a window formed in the top surface that communicates with a channel formed in the bottom surface. A slide member has a thumb tab that extends upwardly through the aperture that allows the slide member to be slid back and forth between a position that indicates whether the door lock is locked or unlocked. The bottom of the slide member is a spring member that has curved lips on the front and rear end that make an audible sound when the slide member reaches both the locked and the unlocked position. The base member has adhesive on the bottom surface for attachment to the head member of a key.
