The Dreambaby Magnetic Lock System is designed to be an ultra-secure lock that is virtually impossible for children to open as it can only be opened with the very powerful magnetic key. The magnetic lock is easy to use as you simply align the magnetic key on the front of the door with the mag lock is unlocked. The magnetic locks are totally invisible from the outside. This magnetic lock can be disabled if protection is no longer needed on a temporary or permanent basis by simply flipping the ‘holdback’ bar at the back of the mag lock.
