The Hidden Risk of Master Keys
When people think about lost keys, the focus is usually on room keys — and the uncomfortable idea that someone might still have access long after they’ve checked out. It’s an unsettling thought.
But here’s what’s often overlooked: while a guest key affects one room, a master key can affect the entire facility.
At Blyx, we’re not here to say keys are bad. They’re essential. Every key has a purpose — but that purpose should never come without visibility or accountability. That’s where smarter key management comes in.
The problem: Trust without visibility
In most facilities, the process is simple — someone signs out a master key, does their work, and (hopefully) returns it. But between those steps, there’s a lot we don’t know. Where did the keys go? Were they used where they should have been? Are they even back on site?
That uncertainty is risky. And it often stays hidden until something goes wrong.
The Blyx solution: Track what matters
The Blyx system brings that missing visibility to life. Every RFID reader within Blyx is fitted with Bluetooth capability, allowing it to detect small, discreet beacons that can be attached to keyrings or any other asset.
As those tagged items move around the facility, Blyx maps their journey in real time. You can see where keys are right now — and where they’ve been. If a master key leaves site or goes missing, Blyx automatically alerts management, so you don’t have to wait for someone to notice. Alerts can even be customised for different users — like a facility manager whose keys legitimately leave site at
The problem: A lost master key
When a master key disappears, the last thing you should do is cut a new one. But in reality, that’s what often happens. The missing key remains unaccounted for — and every door it opens remains exposed.
Replacing or rekeying locks properly can be expensive and disruptive, so many facilities take the risk and hope for the best.
The Blyx solution: Quick, secure, and affordable
With the Australian Lock Company’s Quick Change Barrel system, Blyx makes it easy to do things the right way. Rekeying takes minutes, not hours — no locksmiths or special tools required — so there’s no reason to leave security to chance.
The problem: Too many keys
Even with strong management, the more keys a facility has, the harder they are to control.
The Blyx solution: Reduce the need altogether
Blyx helps limit the number of physical keys by enabling flexible, role-based digital access. Staff and contractors can be given access only to the rooms they need, for the time they need. For physical keys that remain essential, Blyx integrates with smart lockers — replacing sign-out sheets with a digital record of who has what, when, and why.
The best part? The Blyx system costs no more than a standard access control system — it just does more. Beyond managing access, it becomes a foundation for data-driven insight: visibility into movement, activity, and patterns that help your facility operate smarter, not just more securely.
Because when it comes to master keys, knowing is always better than guessing.
