This Ulecoce fingerprint keypad deadbolt combines solid construction with practical smart features for residential door security. The exterior is built with zinc alloy material and a matte black finish, offering resistance to everyday wear and weather exposure. The fingerprint sensor uses semiconductor technology for responsive recognition, while the backlit keypad allows code entry in low light. An integrated app provides remote locking and unlocking, access history, and user management via Bluetooth connectivity. The lock supports up to 100 programmable user codes, accommodating family members, guests, or service personnel. Five physical keys are included as a backup access method. The auto-lock function engages automatically after a preset time, and the one-touch lock feature enables immediate locking from inside. Installation requires only a screwdriver and fits standard door preparations with an adjustable latch. The motor operates smoothly and quietly, and the lock maintains stable performance under typical household use. This model offers a balanced combination of biometric accuracy, electronic convenience, and mechanical reliability at a very affordable price point. The unit is designed for front doors, back doors, or any exterior entry where keyless access is desired. The app interface is straightforward for adding or deleting codes and reviewing lock activity. The deadbolt uses AA batteries and provides low battery alerts.

The construction feels sturdy, and the finish resists fingerprints and smudges. The one-touch locking is especially useful when leaving quickly, while the auto-lock provides peace of mind for forgetful users. The backup keys are cut to standard specifications and can be duplicated locally if needed. This lock is suitable for homeowners or renters seeking an upgrade from traditional keyed deadbolts without requiring extensive wiring or subscription fees. The operation is consistent across different weather conditions and hand sizes.
