I'm looking to extract (if possible) the RFID chip and put it into my wallet... I've also seen people embed the chip from a Tesla valet key into their arm. Not sure I'd like to go that far, but it's an option if the chip and antenna can be extracted from the keyfob. iPad ?
Toyota sells a wallet-sized smart key (well, it's from Lexus) that fits in your wallet. It's available on the 2020 UX and other Lexus models as far back as 2006. Check to see if that's programmable with the Prius. I believe a few members here have tried with the Gen 3 Prius. Lexus Smart Card Key (Credit Card Key) - ClubLexus - Lexus Forum Discussion
