5. Setup and Installation
5.1 Battery Installation
Both locks require batteries for electronic functions. Locate the battery compartment, typically on the underside or rear of the lock. Insert the specified batteries (e.g., AAA or AA, not specified in product data, assume common types) according to the polarity indicators. Close the compartment securely.
5.2 Wall-Mount Lock Installation
The wall-mount lock can be installed on various surfaces to secure long guns.
- Select a Location: Choose a sturdy wall stud, door frame, or cabinet interior. Ensure the location is discreet and provides adequate support for the firearm.
- Mark Drilling Points: Hold the lock against the chosen surface and mark the positions for the mounting screws.
- Drill Pilot Holes: Drill pilot holes at the marked points. Use appropriate drill bits for your wall material (e.g., wood, drywall with anchors).
- Secure the Lock: Align the lock with the pilot holes and secure it using the provided mounting screws. Ensure it is firmly attached and does not wobble.
- Attach Firearm: Place the firearm into the mounted lock, ensuring the trigger guard is properly enclosed.

5.3 Portable Trigger Lock Attachment
The portable lock is designed for quick attachment to the trigger guard of various firearms.
- Ensure Firearm is Unloaded: Always verify the firearm is unloaded before attaching the lock.
- Open the Lock: Use a key or the current access method to open the lock.
- Position on Trigger Guard: Place the lock around the trigger guard, ensuring it fully encloses the trigger and prevents any access.
- Close and Secure: Close the lock firmly until it clicks into place. Test to ensure it is securely attached and the trigger cannot be accessed.
5.4 Fingerprint Enrollment
To enable biometric access, you must enroll your fingerprints. Refer to the specific instructions provided with your lock for the exact procedure, which typically involves:
- Entering programming mode (often by pressing a button inside the battery compartment or a dedicated setup button).
- Scanning your chosen finger multiple times from different angles until the lock confirms successful enrollment.
- Exiting programming mode.
The lock features a 360° recognition scan for reliable and fast access.
5.5 Keypad Code Setup
To set up a personal keypad code:
- Enter programming mode (refer to lock-specific instructions).
- Input your desired new code, followed by a confirmation key.
- Re-enter the code to confirm.
- Exit programming mode.
Choose a memorable but complex code to enhance security.
