The secret clubchouse knock from childhood is back and it couldn’t be better. This new programmable lock allows users to open their door through a series of rythmic knocks, directly attached to the deadbolt on your door. The lock has a mechanism which records and saves patterns of knocking so that whenever you knock this pattern, only this pattern on the door (slowly or quickly), it twists open the lock for you to enter your home.

The Knock Detecting Door Lock allows allows manual control so if you forget the secret knock, you can always open the door with the key. This is an amazing invention although there are some minor flaws. For example, if your neighbors happen to hear your knock, then you’ll have to constantly reprogram the lock so they can’t enter your house, which can get really annoying and unsafe in case you forget to program the lock one day. This is a great device, just avoid listening to rap/hip-hop tracks when you’re programming the lock because to the lock, it all sounds the same. Check out the cool instructional video for the lock.
