If you pull the drawer out as far as it will come, you'll see a small black "tab" on the outside of each glide - where the drawer glide meets the cabinet glide. Simply push one tab up & the other down (you'll have to determine which tab slides in which direction), then pull the drawer all the way out. If it won't come out, push each tab in the opposite direction and try pulling the drawer out. Easiest way to get the drawer back in is to push the cabinet glides back into the drawer opening, align the glides on the drawer with the cabinet glides, and carefully slide in the drawer. You'll probably hear a "click" when each glide locks in place.
