It starts with a simple question.
“Has anyone seen the roof access key?”
And then the search begins. The key hook by the door. The desk drawer. The manager's bag. The box of miscellaneous keys that's been accumulating since 2019.
Sometimes the key turns up. Often it doesn't. And when it doesn't, the real cost starts.
What Does It Actually Cost to Lose a Key?
Most building managers underestimate this. They think about the cost of cutting a new key — maybe $10–$20 at the local hardware store. But a lost key in a managed building isn't just a missing piece of metal. It's a security breach.
Rekeying the Affected Locks
If a master key goes missing — or any key that provides access to common areas, plant rooms, or building entrances — the correct response is to rekey. Every lock that key could open needs a new cylinder, a new key cut, and a new master key issued to authorised holders.
For a building on a master key system — which most managed buildings are — the cost multiplies. Every resident copy, every contractor copy, every committee member's key potentially needs to be replaced.
Management Time
Coordinating a rekeying exercise isn't just a phone call to a locksmith. It means identifying every lock affected, contacting every key holder, arranging access for the locksmith, notifying residents, updating the key register, and distributing new keys. At a realistic estimate, this is a full day of management time — at least.
Insurance and Liability
If the missing key is used to gain unauthorised access to the building and something is stolen or damaged, the liability question becomes complicated. Did the body corporate take reasonable steps to prevent the loss? Was there a key register? Can you demonstrate who had the key and when? Without a clear chain of custody, “we don't know who had it” is not an answer that satisfies an insurer or a committee.
Why Paper Key Registers Don't Work
Most buildings have some version of a key register. It might be a column in the visitor sign-in book. It might be a separate notebook. It might be a spreadsheet that was last updated in 2022.
The problem with paper key registers is not that people don't fill them in. It's that the system has no memory.
A paper register records that Key 7 was issued to “Dave — aircon service” on Tuesday. It doesn't tell you whether Dave returned it, whether anyone checked, or whether Key 7 is currently on the hook or still with Dave.
When something goes wrong, you're not working with a clear record. You're working with a series of incomplete entries, trying to reconstruct a chain of custody from handwriting that may or may not be legible.
What Good Key Management Looks Like
A proper key management system needs to answer four questions at any moment:
- Where is each key right now?
- Who last had it?
- How long have they had it?
- When did they return it?
A paper system can answer questions 2 and 4, sometimes, if the entry was filled in correctly and legibly. It cannot reliably answer questions 1 and 3.
A digital key register answers all four in real time. When a contractor is issued Key 7, the system records their name, company, mobile number, the exact time of issue, and their digital signature acknowledging receipt. If Key 7 hasn't been returned after a configurable number of hours, the system sends an automatic alert. Not “check the hook later” — an alert, right now, on your phone.
The Ochre Keys Approach
Ochre Keys was built specifically for this problem. It's a standalone digital key register designed for building managers — not a feature bolted onto something else, not a spreadsheet template.
Every key in your building gets registered in the system: name, category, cabinet location, and notes. When a key is issued, it's signed out against the visit record. When it comes back, it's signed in. The full history of every key — every issue, every return, every overdue incident — is recorded and searchable.
If a key doesn't come back, you'll know within hours, not weeks. And if, despite all of this, a key does go missing — you have a complete chain of custody to take to your insurer, your committee, and if necessary, the police.
In the event of a claim, a complete key audit trail could be the difference between a covered loss and an uncovered one.
The Number That Matters
Ochre Keys costs AU$10 per month per site. That's $120 per year.
A single rekeying event in a medium-sized managed building costs $2,000–$8,000.
The maths is straightforward. The question isn't whether you can afford Ochre Keys. It's whether you can afford not to have it.
Know where every key is. Always.
Ochre Keys is a cloud-based physical key register for Australian building managers. Track every key, sign in and out, overdue alerts, full audit history. From AU$10/month.
