There are 2 locks, one on the handle, which must be twisted a 1/4 turn to unlatch, and another one up top, about 8 inches down from the top of the door, which is a knob that must be turned 1/2way around. Also the door is very heavy - almost like suctioned in place. My 2 1/2 year old could not budge it and my 5 1/2 year old had to put his entire weight into it.
