One system of record for every physical key
Keys, fobs, door codes, safe combinations — cataloged, issued, returned, and proven on an append-only ledger. Here's what that looks like in practice.
A timeline you can hand to anyone
Every key and every person has one continuous history. Open a key to see each hand it passed through; open a person to see everything they hold. Nothing is inferred — it's recorded.
- Know who holds every key. A live inventory of keys, fobs, codes, and combinations — each assigned to a real person or role, never a mystery drawer.
- See when it changed hands. Every issue, return, and re-key is timestamped on an append-only ledger. The history is the record, and it can't be quietly rewritten.
- Prove why access was granted. Attach the reason, work order, or authorization to each handoff — so a question months later has a one-line answer.

Everything a physical key touches
Physical key inventory
Keys, fobs, lockboxes, gate remotes — cataloged with copies, cut codes, and location.
Codes & combinations
Track door codes, alarm PINs, and safe combinations, including who knows them and when they last changed.
Append-only ledger
Every event is immutable and timestamped. Corrections are new entries, never edits.
Roles & permissions
Assign access to people or roles, with tenant isolation between organizations built in.
Custody chain view
One timeline per key and per person, from first issue to final return.
Audit exports
Produce a clean, filterable history for any date range when someone asks for the record.
Three steps, then it runs itself
Inventory
Add your keys, codes, and combinations once. Group them by property, branch, or building.
Issue & return
Hand off a key to a person or role with a reason attached. Log the return when it comes back.
Prove it
Pull the complete chain of custody for any key, or any person, on demand — for owners, examiners, or peace of mind.
Records that survive scrutiny
Append-only by design
Events are immutable. A correction is a new entry with its own timestamp and author — the trail never loses a version.
Tenant isolation
Every organization's keys, people, and history are walled off from every other. Isolation is enforced in the data model, not by convention.
Role-based access
Grant the right people the right visibility — front desk, maintenance, branch manager, auditor — without oversharing.
Exportable evidence
Produce a filtered, date-ranged history whenever an owner, examiner, or board asks for the record.
