If the iHouse Smartdoor takes your fingerprints to open the door to let you enter your house, then the “Go ahead Key” lets you go out without worrying about your home security. This smart key by Jongoh Lee lets you know if your door is locked properly and you can go ahead. The center of the key turns around thereby indicating open and close of the door. Inserting the key into the key holder and turning it round helps the flexible plastic move to let the homeowner know if the door is properly locked and he or she can feel safe about leaving the house.
