No Battery · No Wiring · No Gateway
NFC Battery-Free Lock System
Digital Lock Management Without Site Infrastructure
The phone carries both the power and the credential.
A smartphone-powered locking system that brings keyless access, app-based authorization, and lower lock-side maintenance to commercial projects — so the lock itself needs no internal battery, no wiring, and no gateway.

Why upgrade
Why Upgrade to an NFC Battery-Free Lock System?
KENRONE NFC battery-free locks are built for real projects. With faster unlocking, competitive factory pricing, and a growing product line, we help customers find a practical lock solution for more applications.
Reduce Key Management
Move away from distributing, collecting, and tracking large numbers of mechanical keys.
Avoid Lock-Body Battery Maintenance
The lock itself does not rely on a built-in battery, helping reduce repeated battery checks across multiple locking points.
Make Access More Flexible
Use mobile authorization to support different users, changing tasks, and temporary access needs.
Improve Traceability
Unlocking actions can be managed and reviewed through the system, making access easier to follow.
What's inside the system
More than a lock — five layers that work together
NFC battery-free locking is more than a single lock format. The system pairs battery-free hardware with smartphone unlocking, app-based authorization, access records, and an open integration layer that can connect into a customer's own platform.
L1
Lock Layer
Hardware
Battery-free lock hardware — cam locks, padlocks, Euro & storage cylinders, and cable locks — built on one shared NFC access platform.
L2
Access Layer
Phone tap
A smartphone unlocks the lock. The phone supplies both the power and the credential during unlocking, so the lock needs no internal battery.
L3
Authorization Layer
App / management
Access is assigned, changed, and removed through the App or management system — across different users, tasks, and temporary needs.
L4
Records Layer
Traceability
Unlocking events can be recorded, managed, and reviewed, so access across many locks and users stays easier to follow.
L5
Integration Layer
API & SDK
An open platform with documented API and SDK, so integrators and OEM partners can connect the locking layer into their own systems.
How it works
Simple for the user, structured for the project.
During unlocking, the phone supplies the power while the system handles authorization and records.
01
Access is assigned in the App or management system
02
The user opens the App on a smartphone
03
The phone is held near the NFC lock
04
NFC transfers power and the lock verifies permission
05
The lock opens, and the event is recorded
The management layer
The brain behind the hardware.
A locking system is only as useful as the layer that decides who gets in. Authorization and records are managed through the App and management system.
-
Assign & revoke access for different users without re-keying hardware.
-
Temporary & task-based access for changing teams, contractors, and short-term needs.
-
Review unlocking records so access across many locks stays traceable.
-
One system, many locks — manage multiple locks, users, and locations together.
Open integration
Built to connect, not to lock you in.
The platform exposes a documented API and SDK, so integrators and OEM partners can connect the locking layer into their own management systems rather than working around a closed app.

// no closed-app workaround

Choosing a method
Mechanical Locks, Battery-Powered Smart Locks, or NFC Battery-Free Locks?
Comparison term | Mechanical Locks | Battery-Powered Smart Locks | NFC Battery-Free Locks |
|---|---|---|---|
Better for | Simple use | Feature-rich smart access | Commercial low-maintenance digital locking |
Unlock records | No | Depends on system | Can be supported |
Digital authorization | No | Usually yes | Yes |
Battery maintenance | None | Required | No battery inside the lock |
Key management | Higher | Lower | Lower |
Lock-body battery | No | Yes | No |
Unlocking | Physical key | App / code / card / fingerprint | Smartphone NFC |
Different locking methods solve different problems. The right choice depends on how many locks you manage, how often access changes, and how much maintenance your project can accept.

What "NFC" means here
What Do We Mean by NFC in This Locking System?
Here, “NFC” is not just a tap-to-unlock feature or a simple way to read information. It supports close-range interaction between the phone and the lock, including access verification, data exchange, and energy transfer during unlocking. The phone helps power and activate the lock, so the lock body can work without a built-in battery.
