Worked
End result: a new working key without paying the dealer price. Yay! Car: 2012 Subaru WRX. Dealer price: $550 The only hitches in the process were: 1) no instructions for the photos of the existing keys. Why three photos? 2) When programming the new keys, the Key Genius app didn't make it clear that you must also program the existing keys at the same time or they'll stop working. This caused drama and excitement.
