LatchHere is what your looking for. They are off the charts expensive so be careful when installing.
for whatever reason they mold the catch and lock together separating and mating the 2 together can be where the frustration begins.
I think i bought this one too as i will use tape or something else then buy a name brand one 20$ these are worth less then 10 cents.
I use caution when ever using these whether on the fridge or converter panel. Up is unlocked sideways is locked. carefully make sure the latch is all the way in before locking. NEVER FORCE they will always break as do they degrade over long time periods.
take your time separating the 2 and even more time pressing the lock into the latch or you will break the new one.
They make them tight so the lock cant jiggle back out. I dont have any great tricks to get them in i think i pressed it in until my finger bled probably broke one of them an somehow got them to go in. Good luck. mine has been in service for a few years after you figure it out
