Love this. Marketing is going to be critical to your success - it's a one-off, low-cost transaction that people rarely need, and you're competing against the keycutting booths in supermarkets that people see at least once a week.
But you've got great novelty. Perhaps create a theme around the idea that you're harnessing CIA technology (well, they've definiely done something similar at some point in the last 50 years). That's likely to get you a decent amount of mileage in the media, and make you stick in people's minds.
Thanks Alex. Yeah my thinking is that the name is critical you will have to remember it for the 6-12 months between hearing about the app and actually needing a key.
The other angle is key 'backup' so you scan all your keys as a backup and if you loose it I send you a PDF you can take to the locksmith and get a key cut whilst you wait. My friend suggested 'KeyBrother' for this service, from the Seinfeld episode :-)
