There are four tabs (two on each side) that you can see on the fixed part of the latch assembly. The tabs are also what the latch slides on. You have to push all 4 simultaneously to pop the latch out. There is probably a special tool available, but I used Channelocks and a tool I fabricated out of 2 pieces of metal drilled for machine screws. They look like two brackets ([ ] ). Place the brackets so each nib touches the release tabs and squeeze with the Channelocks.
