About this item
- 【3 WAYS TO UNLOCK – BIOMETRIC, KEYPAD & KEYS】This biometric gun safe for handgun storage offers three convenient access options: fingerprint recognition, a personal PIN code, and backup keys. The backlit keypad makes it easier to locate the buttons in low-light conditions, while fingerprint access provides a convenient alternative to entering a code. Ideal for use as a car gun safe, bedside pistol safe, or handgun lock box
- 【USB-C EMERGENCY POWER & BACKUP ACCESS】When the batteries run out, connect an external power bank or compatible USB power source to the USB-C port to temporarily restore power to the electronic lock. The included backup keys provide another way to open this fingerprint gun safe. The USB-C port is for emergency power input only and does not recharge the batteries

Its low-profile construction makes it suitable for placement under a car seat, inside a drawer, or beside a nightstand. The padded interior helps reduce scratches and movement of stored items, making this portable gun safe practical for everyday storage and transport
- 【SECURITY CABLE & OPTIONAL MOUNTING】This portable gun lock box includes a steel security cable for securing the safe to a vehicle seat frame or other stationary object, helping deter unauthorized removal. Pre-drilled mounting holes also allow optional fixed installation. Whether used as a gun safe for car storage, truck gun safe, or home handgun lock box, it offers flexible placement options
- 【SILENT MODE & VERSATILE STORAGE】Switch to silent mode for quieter electronic lock operation in shared or low-noise environments.
