The Armoire comes with a child safety lock.  Once you realize how it works it's super simple.  But if you don't realize how it works, it can be confusing!    There's a latching mechanism on the inside of the door that latches onto the "other half" of the locking mechanism mounted on the frame.  This 2 halves of the latching mechanism are all mounted inside the cabinet, so they're invisible.  The "key" is a little while fob or "handle" that ships in the Accessories Box.  That is essentially a magnet (we call it the "Magnetic Wand" or "Magnetic Handle") that dis-engages the latch when you move it over the latch.The parts that confuse most people are:  1) where's located (above the right door handle), and 2) that holding the wand over the lock disengages it -- you need to open the door at that point. Moving the magnetic wand out of the way causes the lock to re-engage.Here's a quick little 34 second video demonstrating the locking functionality.    Once you realize how it works, it's super simple, and very esthetically pleasing because it's hidden from view (no keyholes, etc.)
