Remock Lockey Sounds Weird But Works
Never mind the name, but the Remock Lockey is a remote-controlled lock that was designed to be installed within the door of the room you want to secure, and the same door can only be opened using a small remote control shaped after a key. You will be able to register up to 16 different remotes to a single lock. Good thing the unit is powered by normal batteries purchased via the store, so there's absolutely no reason for you to remain locked out due to dead batteries. Interestingly enough, the Remock Lockey will prevent any locking action from happening if the battery level falls too low for comfort. The Remock Lockey can be yours for $163, which is much more affordable than a dog.
