Verlock™ / Access control

Your key is
the weakest part
of your door.

Every spare you ever handed out is still out there. The ex. The old roommate. The dog-sitter. You can't count them, can't audit them, can't take them back. Verlock™ replaces the key with something nobody can copy or lose.

Hands full. Dark hallway. Doesn't matter. Your thumb is already the key.

Unlock01

The problem nobody counts

A key is a permission you gave away permanently.

You didn't lose your keys. You lost track of them. Here's the audit nobody runs:

  • Copy 01The one you cut for someone who no longer lives here.Still opens your door tonight.
  • Copy 02The one under the mat, in the plant, on top of the frame.The first place anyone looks.
  • Copy 03The one a building manager, contractor or old landlord filed away.Unaccounted for, indefinitely.
  • Copy 04The one in a pocket you'll pat down at 11pm in the rain.One bad night from a locksmith call.

Verlock™ ends the audit. Access becomes something you grant, watch, and take back.

Four independent ways in

One door.
Four ways in.

Not four gimmicks. Four separate systems, any one of which opens the door on its own.

Fingerprint

Thumb on the ring, ring goes green, door opens. No phone, no code, no thinking.

Keypad code

Give the dog-sitter a code on Friday. Delete it Sunday night. No key ever leaves the building.

App unlock

Open the door without getting off the couch. Add a person, revoke a person, read the log.

Mechanical key

Brass cylinder hidden under the base behind a flush cap. The analogue escape hatch that owes nothing to electronics.

One screwdriver.
No locksmith.

Old knob out, Verlock™ in. No drilling, no wiring, no professional.

Why Verlock™

Four things a key
will never do.

Access you can take back

Every person and every code lives in one list. Add someone in seconds, remove them just as fast — no re-keying, no locksmith, no awkward conversation about a spare.

Revocable by design

Three-deep redundancy

USB-C emergency power. A hidden brass key. A mechanical thumb-turn inside. Three fallbacks that don't depend on each other — so "locked out" stops being a thing that happens.

No single point of failure

A sealed exterior face

No exposed screws outside. Nothing to unscrew, pry at or take apart from the hallway side. The shell is the security, before a single electronic feature is involved.

Fastener-free outer shell

Reads as furniture, not hardware

Full matte blackout finish, one etched wordmark, zero gloss. It absorbs light instead of catching it, so it disappears into the door instead of announcing a gadget.

Soft-touch matte black
Share access

Control
from
anywhere.

Grant it. Watch it. Revoke it. From the couch or from another country.

App control03

Access log

Your door
keeps receipts.

A key tells you nothing. Verlock™ tells you who came in, how and when — and lets you end someone's access from the same screen.

Matte blackout

Absorbs light.
Not attention.

Zero gloss. One etched wordmark. Nothing that looks like a gadget.

Finish04

Redundancy engineering

Never
locked out.

The question everyone asks before buying a smart lock, answered before you ask it. Three fallbacks, none of which need the others to work.

Fallback 01

USB-C emergency power

Battery flat at the worst moment? Any power bank on the base brings it back to life on the spot.

Fallback 02

Hidden brass key

A real brass cylinder behind a flush cap under the knob. Fully mechanical, fully independent of electronics.

Fallback 03

3-mode thumb-turn

Inside face, machined dial. Passage, entrance, privacy. Turn it and the door obeys — no app, no battery, no signal.

The port, the brass, the dial. Every fallback, on camera.

Hardware05

Fit check

If you own a
screwdriver,
you're qualified.

  • Check the prepSame hole your current knob sits in. Confirm door thickness is inside [[DOOR_THICKNESS_RANGE]] and backset matches [[BACKSET]].
  • Take the old knob outTwo screws on the interior rose. One Phillips screwdriver. No drilling, no chiselling, no wiring.
  • Seat Verlock™ and tightenExterior face first, interior plate second, screws through. Reversible for left- and right-hand doors.
  • Enrol your thumbRegister prints, set a code, pair the app, file the brass key somewhere sensible. Done in [[SETUP_MINUTES]] minutes.
On the door

This is
the last key
you'll own.

And it's already attached to your hand.

Straight answers

Ask the
hard ones.

What happens when the battery dies?
You still get in. Three separate ways. It warns you long before it's flat. Ignore every warning and you still have three routes: USB-C power on the base, the brass key under the knob, or the mechanical dial inside. A full charge runs about [[BATTERY_LIFE]].
It's a knob — is that actually secure enough?
Stop thinking about it as a lock and think about it as access control. A knob's weakness was never the metal — it was the key, copyable at any hardware counter and handed to anyone. Verlock™ removes that. No exposed fasteners outside, brass cylinder concealed behind a flush cap, every entry logged. Internals: [[MATERIALS]].
Where does my fingerprint actually go?
[[BIOMETRIC_STORAGE]] Prints are stored and matched [[BIOMETRIC_STORAGE]] — never traded, never sold.
Does "control from anywhere" need a separate hub?
[[CONNECTIVITY]]
Will it fit my door?
If a standard knob is on it now, almost certainly. Standard single-bore knob prep, reversible for left- and right-hand doors. Thickness [[DOOR_THICKNESS_RANGE]], backset [[BACKSET]]. Measure once before ordering. A deep profile can foul a tight storm or screen door.
Will the matte finish wear off around the sensor?
The wear point on any fingerprint lock is the sensor ring, so that's where testing matters. Coating [[FINISH_SPEC]], cycle-tested to [[CYCLE_RATING]]. Wipe the ring dry now and then — a clean sensor reads faster.
Cold mornings, wet hands, humid bathrooms?
Operating range [[TEMP_RANGE]]. Water resistance [[IP_RATING]]. A wet thumb reads slower; the keypad code is instant either way.
I rent. Can I take it with me?
Yes — it's a knob swap, not a renovation. Keep your original knob and screws in the box; reverse the install when you move. Check your lease before changing any lock, and ask whether your landlord needs a code on file.
Shipping, returns, warranty?
Shipping [[SHIPPING_WINDOW]]. Returns [[RETURN_WINDOW]]. Warranty [[WARRANTY]].
