Advanced Biometric and Keypad Security

The ONNAIS Iron PRO features both a high-resolution biometric fingerprint scanner and a keypad for unlocking, ensuring that you have multiple options to access your firearm quickly. The fingerprint scanner allows for precise identification and the storage of up to 30 fingerprints, ensuring access for multiple authorized users. The addition of a keypad ensures that even if the fingerprint scanner fails or you are unable to use it, you can still gain access through a secure PIN code.

Backup Key Access

For emergencies, the ONNAIS Iron PRO also includes a traditional backup key, giving you a physical way to unlock the safe if both the fingerprint scanner and keypad fail. This provides a layer of security that ensures you will always be able to access your firearm, regardless of the situation.

Emergency Power Supply

A unique feature of the ONNAIS Iron PRO is its emergency power supply option. If the batteries run out or if there is a power failure, you can connect a USB-C power source to the safe, allowing you to unlock it via your fingerprint or code. This feature ensures that you don’t get locked out of your own safe during critical moments.

Optional Interior Light

The safe comes with a switchable interior light, which can be turned on for better visibility in low-light conditions or kept off for discretion. This feature is especially useful when the safe is placed in dimly lit locations like nightstands or bedside tables.

Spacious and Protective Interior

Despite its compact size, the ONNAIS Iron PRO has ample space to store up to two standard-sized pistols. It features padded interiors to prevent scratches and ensure your firearms remain in excellent condition. Additionally, it can double as a storage solution for other valuables like jewelry, adding to its versatility.

Security Cable for Extra Protection

The safe includes a security cable, allowing you to anchor it to a fixed object such as a table or wall for added security. This ensures that the safe cannot be easily removed or stolen. Additionally, the safe has pre-drilled holes for wall or floor installation, offering another level of protection against theft.

Performance

Biometric and Keypad Functionality

In terms of performance, the ONNAIS Iron PRO generally performs well, with the biometric scanner being responsive and quick to read fingerprints. The scanner works smoothly when used by authorized users, with minimal errors in recognition. However, some users have reported that the fingerprint sensor can occasionally have trouble reading fingers, especially if they are not placed in the correct position. While the keypad is a reliable backup, some users found that the responsiveness of the keypad varies, with some experiencing delays when entering their PIN.

Access Speed

One of the most important aspects of any gun safe is the speed at which it can be accessed, especially in an emergency situation. The ONNAIS Iron PRO does a solid job in this area. When working properly, both the fingerprint scanner and the keypad provide quick access to the safe, with most users reporting that the safe can be unlocked in a matter of seconds. The added benefit of the emergency power supply further enhances access speed in the event of a battery failure.

Durability and Construction

Made from alloy steel, the ONNAIS Iron PRO is a sturdy and robust product. The steel construction ensures that the safe is resistant to tampering or damage, providing reliable protection for your firearms. Additionally, the inclusion of a security cable allows users to further anchor the safe, increasing its resistance to theft.

Battery Life

Battery life is an important consideration when choosing any electronic lockbox. The ONNAIS Iron PRO uses standard batteries, and while the exact life span varies depending on usage, many users have reported that the battery lasts a reasonable amount of time before needing to be replaced. The addition of the USB-C emergency power option is a thoughtful feature, providing peace of mind if the batteries run out unexpectedly.
