Way to carry keys with Bellroy Flipcase

My problem:

• 2 keys and 6 cards
• carry keys inside my wallet and with a closure or a retention cord so I dont lose keys
• thin, water-resistent
• everything should be easily accessible.

It's not easy to find a wallet that does this though. After a couple month of use I can conclude that FlipCase does this job perfectly with a little tweak.

About the wallet:

• 2-card quick-access slot and 8-card slot (or 6-card with a bank note, there is a divider, see image)
• magnetic closure, so relatively water-resistent

About the keys:

Basically, I use the quick access slot to keep my 2 keys.

The coin on the right side does 2 things:

1. it keeps keys from moving around in the quick access slot
2. it keeps some emergency floss

I advice against keeping more then 2 keys in the quick access card slot. The third key would be placed on where the coin is, and it would be hard to dig that out.

About the cards:

I only have a credit card and a gym key that I use daily, so I keep one on the top of the stack, relatively easy to use my thumb to swipe it out; the other on the other side of divider. As shown in image.
