Lost Key Locator

Like the fairy godperson they never had, this smartphone-compatible homing device will always be there when they need it most. Think of the far-ranging implications of ending the problem of lost keys for good: it can save them from missed social dates, get them to work on time, and spare them the toxic neurological effects of chronic frustration. It may seem like a small gesture, but helping a poor soul stop losing their keys can be a life-changing gift indeed.
