🔑 What BigKeyRing is
A practical key inventory for your phone or computer. Save clear photos of each key,<br>note which lock it opens (and where), then match a mystery key later by taking another photo.<br>No more trying every key on the ring.
📋 How it works
Add a key — snap 2–3 clear photos of the blade (teeth side works best).<br>Take it off the ring first.
Label the lock — e.g. “Front door”, “Shed”, “Unit 4B”. Optional map pin for the location.
Identify later — photograph an unlabeled key; BigKeyRing matches it against your library.
