Lost-Key Service

Document key loss and handle find reports easily.

Each key gets a unique QR ID on the tag — without private contact details on the ring. Finders report the find; owners are notified by email.

How the finder flow works

From key setup in the app to owner notification — in five steps

Create key with Lost Key QR on object

Create a key on the object: assign an ID, enable Lost Key, and generate the QR code.

Scan QR code on key tag

Scan or assign the QR code on the tag — the key is uniquely linked to the object.

Key is lost

The key is lost — only the anonymous QR ID remains visible on the tag.

Finder scans QR and leaves contact details

The finder scans the QR code and enters their contact details on deep.rent/lost-key.

Owner receives email notification

The owner (configured email) receives a notification that the key was found.

Identify keys in the app

From tag to scanner — QR setup, finder report, and scan result

Key with tag and QR code

Each key set gets a unique ID — on the tag as a QR code, without private contact details.

Capture QR code in key editor

In the key editor: assign an ID, enable Lost Key, and generate or scan the QR code.

Finder reports found key

Finder scans the QR code and reports the find — the owner receives an email.

Scan result with object and key description

In the app: start a scan — object name, key ID, and description; open directly with “Go to object”.

Keys and access codes can be fully documented in the protocol app. With the Lost-Key Service, each key gets a unique QR ID on the tag — without private contact details on the key ring.

Enable the module

Turn on Lost-Key Service under Settings → Modules. For each key you can generate a loss QR code and set an email contact for find reports.

🎯 Get lost keys back faster — and instantly see what a key is for in daily use.
