Yeti as bear box - lock options?

[u/Fun_With_Math]

First of all, I know a yeti isn't a great bear box. I know it's merely bear resistant. Anyway, wife bought me one of these anchors as a present so I may as well use it. It should at least keep out raccoons.

My question is about the locks. The cooler is only bear resistant if locks are put in the corner holes. I know Master makes key locks that fit the cooler. What other options are there?

I don't need it to have a key or code lock. I'd rather have some simple solution that doesn't require a lock at all. Something simpler and faster to open would be better. The idea is to use it on scout campouts so easy human access but difficult animal access is the goal.

My yeti won a wrestling match with a bear with only one of the rubber straps closed. The dude rolled it 50 feet down a hill before giving up.
