Quick Release Bear Proof Cooler Lock bearbolts.com Review, Keyless 

Hello all, this is a demo of the bear proof locks I bought for my cooler. These are used for camping in the back country to prevent bears from breaking into your cooler and stealing your food. There are no combinations or keys and no small parts to lose. All you have to do is push a quick release button to release the lock. I bought these because I was afraid of losing my keys. These are certified by the Interagency Grizzly Bear Committee.

The website has a list of compatible coolers. Includes Yeti, Igloo and many others. Fits well on this Engel.
