Can't remember if you locked your front door this morning? Let the Memory Key remind you! Just clamp the Memory Key housing over your existing house key and place the small marker on your door lock. Now every time you lock or unlock the door, the Memory Key will recognize it and store that information in its memory. So the next time you wonder whether you've locked the door, you can just look at the key!

The LCD display shows you the status of the door (locked or unlocked) and how much time has passed since you locked the door with that key. (See diagram on this page for examples of LCD display.) The Memory Key works with all popular cylindrical lock keys and all popular cylindrical locks that need a 360° turn for locking or unlocking. Battery is included; LCD will show when the battery needs to be replaced.
