With KnoKey you will never again forget whether you locked the door or not — or rather, when you do, KnoKey remembers it for you. No smartphone, no battery, no blinking lights, all KnoKey asks from you is an extra half a turn at the beginning of each locking and unlocking.

An add-on piece to existing keys might be a good alternative for easier distribution and / or market fit testing.
