The Best Way to Recover Lost Keys: a Free QR Keychain
Studies put the average adult at four lost-keys events per year. About one in twenty involves a real replacement — locksmith, lost deposit, panic. A 2cm plastic QR tag on the keyring fixes most of that.
Why most lost keys never come back
Keys without a tag are anonymous. The honest stranger who finds them at the café picks them up, looks around, and has no idea what to do. They’ll either hand them to the staff (best case) or take them home, planning to "post on Reddit later," and forget. A small QR turns that uncertainty into one tap.
Tag placement that actually works
- The QR disc. Plastic, ~2cm, on the same split-ring as the keys. Front side has the QR; back side says "Scan to return" in three languages. Free template in the dashboard.
- Don’t put your address. Old-school engraved name tags with home addresses are how burglars find unattended apartments. The relay is the whole point.
- Optional reward note. "$20 reward" doubles the speed of return. Worth it for car keys.
Setup in 60 seconds
- Open Tagback dashboard, "Create tag" → Item → Keys.
- Optional: add the make/model of your car or apartment block (this is for *your* memory; finder doesn’t see it).
- Print the QR disc template on plastic paper, or order an aluminium key-tag.
- Slide onto the keyring. Done.
Backup placements people forget
- Behind the car-fob plastic. Open the fob, stick a small QR sticker on the inner shell.
- Inside the wallet keys-pocket. Some wallets have a tiny pocket for the spare car key.
- On the bicycle helmet. If you bike to work, the helmet sometimes goes home with the bike.

FAQ
Where on the keyring should the QR go?+
On a small plastic key-tag the size of a thumbnail, attached to the same ring as your keys. Big enough for a phone camera to scan from 15 cm. The tag has a hole that fits a standard split-ring.
Will I look weird carrying a "QR keychain"?+
Plenty of car-key fobs and gym membership cards already use barcodes and QRs. The Tagback tag is a 2cm plastic disc — looks like a normal keyring decoration, not a tracker.
AirTag on the keyring — better?+
Different problem. AirTag tells *you* where your keys are within Bluetooth range; QR tells the *finder* how to reach you. AirTag won’t help if your keys are 200 km away in a Lyft. Many people use both: AirTag for daily forgetfulness, QR for "actually lost."
What if a thief scans the tag and learns I live nearby?+
The QR doesn’t reveal your address. The finder gets a "Message owner" button. They can’t see where you live unless you choose to share. Phone number stays hidden too.
