Argosy Minuet 77 refrigerator lock key

[Cliftonmc]

Calling on any Argosy Minuet 6.0 owners, does your refrigerator access panel lock key match your battery box key, or water access key? I've ordered a few different ones from Out of Doors Mart and have managed to open the water and battery box but can't seem to get the fridge access panel open. So far I've tried the 751, 1101X, and LL432 keys.

I'm not sure if it is just a sticky lock or a different key altogether. From the look and age of the lock it seems to be original.

Thanks!
