So my understanding is we need to purchase these keys off of the Prism shops in order to unlock each card. And if we want to remove a code from a card we need to use the 4th item? The one that looks like a scraper-thingy (currently on the shop for 100 prisms).

The unlocking seems fair; but the removing mechanism is a bit bogus; especially if it will be rare prism only.
