Chances are high that we feel disturbing, experiencing forgetting to lock the door, or forgetting locking the door. Forgetting to lock leads to property danger, while forgetting locking leads to waste of time returning to check.
“Locked” is a key with a “locked & unlocked” reminder. When the door this key is to is unlocked, an “unlocked” reminder appears on a side of the key as a warning: “The house is not safe! ”. While the door is locked, a “locked” reminders appears on the front of the key telling: “Don’t worry, house secured.” This will help avoid inconveniences of unnecessary returning.
