What BigKeyRing is

A practical key inventory for your phone or computer. Save clear photos of each key, note which lock it opens (and where), then match a mystery key later by taking another photo. No more trying every key on the ring.

How it works

  1. Add a key — snap 2–3 clear photos of the blade (teeth side works best). Take it off the ring first.
  2. Label the lock — e.g. “Front door”, “Shed”, “Unit 4B”. Optional map pin for the location.
  3. Identify later — photograph an unlabeled key; BigKeyRing matches it against your library.

Who it’s for

Households Too many keys, one shared ring — keep a labeled library for the family.
Landlords & hosts Units, lockboxes, and guest keys — find the right one fast.
Facilities & teams Business (up to 50) or Business Unlimited seats — each person has their own login.
