I got locked in our coop after we first put the latch in, too. Now I just have one of those string lanyards with the little hook on it attached to the latch and fed through the screen. Then I put a washer on the end of the lanyard and tied a knot in it. I new my husband would try to be cute and pull the lanyard through the fence screen when I was locked in. Also, you can open the latch and put your carbiner in the lower hole to hold the latch open, then you can't get locked in!
