FlashLock is a keyless lock that opens using light. You hold your phone screen against the face of the lock, the screen flashes a coded pattern, and if your access is valid the lock flashes back and opens.

No app to install. No wiring to run. No power at the door. No key to lose.

It sounds like a gimmick until you think about where locks actually need to go.

The problem with the places that need locks most

Access control is easy on an office door. There is power in the wall, a network drop nearby and someone to maintain it.

Now put a lock on a gate at the far end of a property. A pump house. A vending machine. A storage cabinet in a building you do not own. A cabinet at a remote site that gets visited twice a year.

Suddenly the conventional answer requires trenching, conduit, a power supply and a controller, and the cost of securing the thing exceeds the value of what is inside it. So most organizations do what everyone does: they put a padlock on it, hand out copies of the key, and lose track of who has one.

FlashLock exists for exactly those doors.

How it works

You get a link, not an app. Access arrives as a secure link by text or email. You open it on any web-enabled device.

The screen talks to the lock. Hold the screen to the lock face. It flashes a coded sequence of light. The lock reads it.

Rolling codes prevent replay. Each access uses a unique code, the same principle a modern garage door opener uses. Capturing one flash sequence gets an attacker nothing, because that code is already spent.

It opens, and it writes it down. The lock logs who opened it and when. Real time text alerts can be sent on access attempts.

It runs on a battery. A single CR123 lithium cell, typically about a year with regular use. No wiring, no power supply, no controller.

Access methods

FlashLock is not phone-only, which matters for the crews who would rather not use a personal device for work.

  • Smartphone or any web-enabled screen
  • A web link sent by text or email, useful for one-time or temporary access
  • A compact fob for people who carry one
  • CyberKey, if you already run a CyberLock system

That last one is the reason this fits alongside the rest of the platform rather than being a separate island. FlashLock can live inside a larger CyberLock deployment instead of becoming a second system with its own administration.

Temporary access without handing over a key

This is where it earns its place most often.

A contractor needs to reach a remote cabinet on Thursday afternoon. A delivery needs to get into a gate once. A technician is coming to a site four hours away and you would rather not drive out to meet them, and definitely not mail them a key.

You send a link with a window attached. It works during the window. It stops working after. Nothing was mailed, nothing was copied, and there is a record of whether they actually showed up.

Compare that with the alternative, which is a key under a rock and a phone call afterward asking whether it went fine.

Where it fits

  • Gates and perimeter access at remote sites
  • Cabinets and storage rooms
  • Pump houses, utility enclosures and outbuildings
  • Vending and unattended equipment
  • Dorms, apartments and vacation properties
  • Mechanical items, using the FlashBox accessory

FlashLock or CyberKey?

They solve overlapping problems and the honest split is straightforward.

CyberKey suits an organization standardizing a workforce on one credential across many locks, where the key carries permissions and powers the cylinder.

FlashLock suits access that is occasional, temporary, or granted to people outside the organization, where issuing a physical credential at all is the thing you are trying to avoid.

Plenty of sites run both, with FlashLock handling the doors that visitors and contractors touch and CyberKey handling staff.

The short version

FlashLock puts audited, revocable, time-limited access on doors that cannot justify wiring and were never going to get it. If your answer at those doors today is a padlock and an unknown number of copies, this is the alternative.
