NFC Battery-Free Lock System for Commercial Access
KENRONE combines battery-free NFC lock hardware with smartphone unlocking, app-based authorization and access records. At the tap, the phone provides both the power and the credential, so the lock itself needs no built-in battery, wiring or gateway to open.

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.
The hardware layer
A Shared Platform Across Multiple Battery-free NFC Smart Locks Formats
Choose the hardware that matches the opening; keep one battery-free NFC access approach across the project.
How it works
One Tap Powers and Verifies the Lock
An authorized user opens the KENRONE app and places an NFC-enabled phone against the lock's NFC area. Within 1 cm—normally with the phone touching the lock—the phone energizes the electronics, the lock verifies permission and the mechanism releases. The current generation typically completes the sequence in 0.5–2 seconds under suitable phone, placement and authorization conditions.
01
Assign access — Add, change or revoke user permissions in the KENRONE app or connected management system.
02
Tap the lock — The smartphone supplies energy and an encrypted credential over NFC.
03
Verify and open — The lock verifies permission locally and releases; supported deployments retain an unlock record.

What the Management Layer Does
The KENRONE app and management platform support user authorization, permission changes and unlock records. Documented API and SDK resources are available for qualified integration projects. Offline unlocking can be supported by the deployment design; confirm the required authorization and synchronization workflow during specification.
Authorization Layer
App / management
Access is assigned, changed, and removed through the App or management system — across different users, tasks, and temporary needs.
Records Layer
Traceability
Unlocking events can be recorded, managed, and reviewed, so access across many locks and users stays easier to follow.
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.
Open integration
Manufactured for Integration and OEM Projects
KENRONE has worked in locking products since 2002 and has focused on battery-free NFC locks since 2020. Product design, manufacturing, assembly and testing are supported from our Huizhou facility. We work with lock brands, cabinet and locker manufacturers, integrators and project buyers on standard products and qualified OEM/ODM programs.

Choosing a method
Mechanical Locks, Battery-Powered Smart Locks, or NFC Battery-Free Locks?
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.
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 |
