The TEEHO TE004 keyless entry keypad door lock with handle offers a practical and secure access solution for interior doors. Constructed with a durable matte black finish, the unit combines a sturdy zinc alloy body with a smooth, wear-resistant surface that resists fingerprints and smudges. The electronic lock operates on four AA batteries, providing reliable power for extended periods. Its compact design integrates both the keypad and handle into a single, streamlined unit, making it suitable for bedrooms, home offices, bathrooms, or storage rooms where keyless convenience is desired.

The lock features an anti-peeping function on the keypad, allowing users to enter a longer code with extra digits to obscure the actual password, enhancing security in shared or public spaces. An auto-lock mode engages the lock automatically after a preset time, ensuring the door is never left unsecured. The passage mode disables the locking mechanism temporarily, enabling free entry without a code—ideal for situations like frequent movement or cleaning. With customizable user codes (up to 20 codes) and a simple programming process, the lock adapts to different household or small office needs.

From an engineering standpoint, the lock operates smoothly, with a responsive capacitive touchpad that registers inputs quickly and accurately. The handle mechanism uses a spring-loaded latch, providing a satisfying, quiet closure. Installation is straightforward, requiring only a screwdriver and about 15 minutes to replace an existing interior door knob. The lock fits standard door preparations with a 2‑1/8 inch bore hole and adjustable backset (2‑3/8 or 2‑3/4 inches).

The matte black coating adds a modern aesthetic that complements various interior styles while resisting corrosion and daily wear. The TEEHO TE004 delivers reliable performance without excessive complexity. It uses low‑power consumption technology, with a low‑battery indicator on the keypad to prompt timely replacement.

The lock’s IP54 rating offers basic protection against dust and light moisture, appropriate for indoor use. With a competitive price point around fifty dollars, this digital lock presents a good balance of functionality, build quality, and affordability. It suits users who want to upgrade from traditional keys to a code‑based access system while maintaining easy operation and dependable security for interior doors.
