Simple playpen door latch

I hate the latch for the door on my Dwinguler play pen. It is way too low for me to reach when carrying my infant. I'm recovering from a C-section so stepping over the walls works fine for my husband but not for me. The built in latch is really hard to close too, you have to get the holes lined up just right. Probably will be useful when baby is older, but right now it's just too difficult to manage when going in and out with baby. I need to make sure the door gets shut because I have 4 dogs who
