Magnetic Key Holder, under Kitchen cabinet

I needed a way to mount a magnet under my kitchen cabinet to hold my keys. My cabinets have a 1" recess under the bottom, so the part is 1" overall in height. I used magnets from my local Ace Hardware and 5 Minute two part epoxy to glue them in. I installed the brackets with 2 drywall screws.

One of my cabinets has a 135 degree angle in the corner, the other has a 90 degree corner. The magnet recess in the part is .737" diameter.

Here are the magnets I used:
