Specifications & Installation Requirements

Everything needed to evaluate KEYVOX without a call: which model fits which door, full datasheets, installation requirements and wiring.

Read this first

Availability and certification

KEYVOX is a Japanese manufacturer. Hardware and software have different availability, and confusing them wastes everyone's time — so here is the position up front.

Hardware (QR1 LE, BR1, WD1, BX1, lockers): Certified for Japan only, under the MIC technical conformity mark (技適). FCC, CE, UKCA, RCM and IMDA certifications are not held, so the hardware is not sold outside Japan today. If you are evaluating for a site in Japan, everything on this page applies as written.
Cloud platform, UnlockOS and REST API: No such restriction. The software side is used with locks already installed on site, including third-party locks such as CANDY HOUSE SESAME, igloohome and Akuvox.
Third-party lock support: Added model by model, not by brand. Ask about the specific lock model you have rather than assuming it is or is not supported.

Model selection

Which model for which door?

Start from the door, not the product. Each row below is a complete configuration.

Your door

Deadbolt with a physical key

Guest rooms, offices, apartment units, rental spaces

Configuration

QR1 LE + PiACKII

QR1 LE

Key requirement: Door thickness 33–50 mm, backset ≥ 51 mm, and a compatible MIWA lock case. See installation requirements below.

If the door cannot be machined and physical key handover is acceptable: QR1 LE + BX1 lock box. If it is not acceptable: QR1 LE + CANDY HOUSE SESAME.

Your door

Electric lock or electric strike

Office entrances, coworking spaces, gyms, saunas, spas

Configuration

QR1 LE + BR1 (Wi-Fi) or QR1 LE + WD1 (wired LAN / PoE)

QR1 LE

Key requirement: The controller must accept a voltage-free dry contact input. Locking and timer behaviour stay with the electric lock and its controller.

Choose WD1 where Wi-Fi is unreliable or where the door is already on a wired network. Proven with MIWA, GOAL and WEST electric locks.

Your door

Automatic door

Commercial building entrances, school entrances

Configuration

QR1 LE + BR1 or WD1

QR1 LE

Key requirement: Coordination with the automatic door manufacturer is required. An electric lock unit is needed for automatic door control.

Proven with NABCO, Teraoka Auto Door, Sanwa Shutter and Showa Door.

Your door

Roller shutter, gate or fence — outdoors

Self-storage roller shutter doors, RV park chain gates, skate parks, dog runs

Configuration

QR1 LE + BR1 or WD1 driving an electromagnetic lock

QR1 LE

Key requirement: QR1 LE itself is rated for outdoor use. BR1 and WD1 are not weatherproof and must be installed inside a weatherproof enclosure.

Proven with MIWA, Lavish, Bunka Shutter and Shikoku Kasei. Per-door units are individually addressable, so one shutter door per contact output.

Your door

A door where nothing can be installed

Property viewings, contractor access, vacation rentals, guesthouses

Configuration

BCL-BX1 lock box

BCL-BX1

Key requirement: Stores the physical key. Runs standalone with the KEYVOX Basic mobile app, or paired with QR1 LE for the full cloud feature set.

One QR1 LE can control multiple lock boxes (Japan Patent No. 7717415).

Your door

Locker doors

Package handover, key handover, staff lockers, rental pickup, mail centres

Configuration

KEYVOX Smart Locker

Smart Locker

Key requirement: Custom manufactured from a single unit — internal dimensions, external dimensions and colour are all specified per order. Lead time is 3 months.

Same REST API as the locks, so an entrance door and a locker can share one QR code.

Not sure which row applies? Send the lock case marking stamped on the edge of your door, or a photo of the door and its frame.

Installation

Installation requirements

Check these before quoting. They are the conditions that decide whether a door can take KEYVOX at all.

Mounting the QR1 LE

QR1 LE mounts on the frame side of the opening, not on the door leaf, so no power or cabling crosses the door. Three mounting methods are supported.

Wall opening for QR1 LE: 83.5 mm screw pitch, 51 × 95 mm cutout, 2Φ conduit hole.

Switch box: Use a standard box with an 83.5 mm screw pitch. Follow the box instructions for the opening. Run conduit of at least 20 mm through the wall to the power location, then pull the USB power cable out of the back of QR1 LE and through the conduit.
Direct wall opening: Either fit a scissor bracket with an 83.5 mm screw pitch, or cut a cable-only opening. Cutout for the scissor bracket is 51 × 95 mm; the conduit hole is 2Φ. Fix with screws or double-sided tape.
Surface raceway: Take the USB cable out of the raceway groove on the bottom of the unit — there is a groove on the bottom only — and run it in surface trunking to the outlet.
Power reach: The supplied USB cable is 3 m. If the outlet is farther than 3 m, use the optional 6 m adapter (BCL-ADQR).
Outlets: When powering QR1 LE from BR1, provide one AC100V outlet for BR1. When powering them separately, provide a second AC100V outlet.

Mounting height

Adjust to the height of your users. The most common setting puts the centre of the middle hole of the QR1 LE bracket 1,200 mm above the finished floor.

1,200 mm from the floor to the centre of the cable hole.

PiACKII deadbolt requirements

PiACKII replaces the interior thumb-turn on a MIWA deadbolt and keeps the physical key cylinder in place. Four conditions must all be met.

Door thickness: 33–50 mm
Interior side: 16.5–25 mm, measured from the centre of the lock case to the interior edge of the door
Backset: 51 mm or more, from the edge of the door to the centre of the thumb-turn
Power: 4 × AA batteries in PiACKII. Battery level is readable through the cloud, but once the batteries are flat the door can be opened only with the physical key — plan an emergency key procedure before deployment.
Included: Auto-relock door sensor

Compatible MIWA lock case markings

The marking is stamped on the lock case, visible on the edge of the door.

13LA
DA
10DAF
DAF
LA・MA
LAF
LDAL
LE
WLA
08FE
08LEF
TE

FESP

If the marking is not on this list, the door needs a new lock case, or an electromagnetic lock driven by BR1/WD1 instead.

Radio requirements

These are the conditions that most often fail a site survey. Measure before you quote.

Wi-Fi: 2.4 GHz Wi-Fi at -70 dBm or better is required outside the door, at the QR1 LE position.
Bluetooth — acceptance criterion: -70 dBm or better between QR1 LE and the paired device, measured with the door both fully closed and fully open.
Bluetooth — design distance: Within 50 cm for QR1 LE to PiACKII. Within 2 m for QR1 LE to BR1. No steel or concrete between the two units.
Environments that usually fail: Steel doors and concrete walls generally do not meet the radio requirement. Congested RF environments such as major terminal stations and exhibition halls may not operate reliably. Contact support before committing to these sites.

Contact output and emergency access

How the contact signal behaves, and what you must provide alongside it.

Contact signal duration: 2 seconds by default, configurable between 2 and 20 seconds. Contact KEYVOX support to change it.
Contact type: Voltage-free A contact (NO) or B contact (NC). Connect to the controller with 2-core AE0.9 cable, not supplied.
Emergency access: Agree an emergency unlocking method with the electric lock or automatic door manufacturer and the installer — for example an emergency release button — for the case where the door cannot be unlocked.

Wiring

Wiring configurations

The three supported configurations, with the interface between each pair of components.

QR1 LE + BR1 — electric lock or automatic door over Wi-Fi

Wireless between the reader and the module. Suitable where running LAN to the door is impractical.

2.4 GHz Wi-Fi at -70 dBm or better is required outside the door.
When PiACKII batteries are flat, the door opens with the physical key only. Plan the emergency key procedure before deployment.

Developers

API and integration

Locks and lockers share one REST API, so an entrance door and a locker can be driven by the same credential.

Authentication: API key and secret with HMAC-SHA256, or OAuth 2.0. Server IP addresses can be allowlisted.
Response format: JSON (code, msg, data)
Developer dashboard: Issue API keys, configure OAuth tokens and IP restrictions, set up webhooks, and read real-time request logs.
Webhooks: Supported, configured from the developer dashboard.
AI tooling: Major endpoints are exposed as MCP tools.
Throughput: Scales without interruption to 3 million calls per month. Sustained call rates above the plan allowance are billed on usage — ask for details.
