iulock vs TMEZON Smart Door Lock: Which keyless lock is better in 2026?

Keyless door locks are becoming a practical alternative to conventional hardware, but not every model is designed for the same type of user. Some focus on simple PIN-based entry and low maintenance, while others add fingerprints, smartphone control, and multiple authentication methods. 

The iulock IU-30 Keypad Smart Door Lock and TMEZON T8 Smart Door Lock represent these two approaches, with the iulock prioritising simplicity and the TMEZON adding more connected access options.

iulock vs TMEZON Smart Door Lock specs

iulock IU-30 Keypad Smart Door Lock

The iulock IU-30 is built for users who want keyless access without the complexity of apps, Bluetooth pairing, or smart-home gateways.

Its biggest strengths are simplicity and endurance. Four AAA batteries can provide up to 18 months of operation, while an emergency USB-C port offers a backup option if the batteries are depleted.

However, the IU-30 is deliberately limited in its smart capabilities. There is no fingerprint reader, smartphone app, Wi-Fi, or remote access.

TMEZON T8 Smart Door Lock

The TMEZON T8 takes a more feature-rich approach. Alongside keypad and mechanical-key access, it adds fingerprint recognition, IC cards, and Tuya app control. 

Its fingerprint sensor can reportedly recognise users in approximately 0.2 seconds, while storage for more than 50 fingerprints and up to 100 cards makes it suitable for larger households, offices, and rental properties.

Which one should you prefer?

The TMEZON T8 is the better choice for users who want maximum access flexibility, particularly fingerprint entry, IC cards, and app-based management.

The iulock IU-30 is better suited to buyers who value simplicity, long battery life, and affordable keyless entry rather than connected smart-home features.
