Update Security Code in Apple Wallet

My updated Wells Fargo debit card kept the old Security Code. I've searched everywhere for how to solve this and finally sorted it out. This is exactly how to do it.

1) Open wallet on your iPhone.

2) Open the card you want to update.

3) Open Card Details.

4) Remove card.

5) Reinstall. It shows up under the title of Previous Cards.

6) Viola!

I'm not certain if there is a similar way to do this under System Settings on the Mac... but I wouldn't be surprised.
