fireproof safe fingerprint lock

Most models combine biometric fingerprint access with an electronic keypad and at least one physical emergency key. Many advertise dual electronic-and-key operation and may offer external power/backup options (e.g., USB power or an external battery box) for added redundancy.

Most biometric home safes use replaceable batteries (commonly 4 AA or 4 AAA) as their primary power source. Many also support external power via USB-C/Type‑C or an external battery box, and most include an emergency backup key or mechanical override for access if electronic power fails.

Many models include tamper protections such as dual alarm systems that trigger after multiple incorrect fingerprint or password attempts and impact/vibration sensors that sound on strong knocks or movement. Some units also offer configurable mute or alert modes tied to tamper events.

Common interior features include removable or height-adjustable shelves and dividers, carpeted floor mats to protect contents, and built-in lights in some models to improve visibility.

Weights vary by size and construction: compact models can weigh around 20 pounds, while larger units shown in listings can weigh up to about 122.36 pounds. Exact weight depends on capacity and materials used.

Some listings explicitly note certifications such as ETL listing and CE certification on individual models. Certification presence varies by model and region, so check each product's listing or label for specific safety and compliance marks.
