SUBPOT E02 vs Nyboer H3B Smart Keypad Door Lock: Which one is a better option in 2026?

Smart locks come in different forms, from simple keypad deadbolts to feature-packed systems with fingerprint recognition, smartphone control, and Wi-Fi connectivity.

The SUBPOT E02 and Nyboer H3B take noticeably different approaches. The SUBPOT E02 focuses on simple, offline keypad access with a complete door-hardware setup, while the H3B offers biometric entry, app control, Wi-Fi connectivity, and multiple smart-home features.

SUBPOT E02 vs Nyboer H3B specs

SUBPOT E02 Smart Keypad Door Lock

The SUBPOT E02 is designed for homeowners who want straightforward keyless entry without the complexity of a connected smart-home system. 

Instead of relying on Wi-Fi, Bluetooth, or a smartphone app, it uses a keypad and physical backup keys for access.

One of its biggest advantages is that it comes as a complete hardware package, combining the electronic keypad deadbolt with two matching door knobs. This makes it a practical option for users replacing an entire front-door lockset rather than upgrading only the deadbolt.

Nyboer H3B Smart Keypad Door Lock

The Nyboer H3B takes a much more feature-rich approach to smart entry. It combines fingerprint recognition, touchscreen PIN entry, smartphone app control, key fobs, voice control, Wi-Fi remote access, and mechanical keys into one system.

Its standout feature is the 9.25-inch extended panel, which is designed to cover two existing door holes. This can make it particularly useful when replacing older lock hardware because the larger faceplate can conceal existing openings without requiring additional drilling or patching.

Which smart keypad door lock should you buy?

The SUBPOT E02 is the better choice for users who want a simple, affordable, offline keyless entry system with a complete door-hardware package.

The Nyboer H3B is the stronger option for users who want a fully connected smart lock with biometric access and remote management.
