The Prezlock Pebble can store up to 100 fingerprints, making it incredibly convenient for sharing access with family, friends, or colleagues. Setup is a breeze—many customers note how simple it is to program the MASTER fingerprint. Once the MASTER is set, you can easily authorize and add additional users in seconds.

Not at all! The lock comes with 2 physical backup keys for emergency access. If the battery runs out, simply insert the key into the bottom cylinder and turn it 90° clockwise to unlock. Additionally, connecting a USB power bank to the Type-C port will instantly resume normal operation.

Powered by advanced lithium battery technology, the built-in 300mAh battery provides up to 6 months of standby time or approximately 3,000 unlocks on a single charge. It fully recharges in about 2 hours via the included Type-C cable. (Note: To be environmentally responsible, a wall charger is not included; any standard USB power source will work).

The lock features a built-in low battery alert. If you touch the fingerprint sensor and a red light blinks continuously for 5 seconds, or if a red light appears when you press the shackle, the battery is running low. We recommend recharging it promptly when you see these indicators.

Yes, it features an IP65 weatherproof rating, protecting it against rain and dust. It operates reliably in extreme temperatures ranging from -4°F to 140°F (-20°C to 60°C). However, please avoid submerging it in water or laying it flat where water could pool into the charging port for extended periods.

The padlock is built for heavy-duty security. It features a solid alloy metal body protected by a durable TPU shield, and an 8mm Boron Steel shackle with PVD plating to resist rust. It boasts a US ASTM Grade 3 Security Rating and utilizes a patented Double Ball Bearing locking mechanism that can withstand over 1,000 pounds of pulling force, protecting against prying and cutting.

Absolutely! It’s highly recommended for gym lockers, school lockers, toolboxes, and cabinets. The quick biometric sensor opens the lock in under a second, eliminating the need to remember combinations or carry keys during your workout. (Note: The shackle clearance is 23 x 27 mm, which fits most standard lockers perfectly).

To erase all stored fingerprints, unlock the padlock, then press and hold the button for at least 5 seconds until a white LED blinks. You must then verify this action using your MASTER fingerprint (the LED will turn green). Once verified, all fingerprints are erased, and the lock returns to factory settings.

The lock is equipped with a precise 360° biometric module designed for fast and accurate recognition. However, like all biometric sensors, performance is optimal when your finger is clean and dry. If the sensor or your finger is excessively wet or greasy, simply wipe it off, or use the backup key if necessary.

Yes, you can travel with it. However, due to aviation safety regulations regarding devices with built-in lithium batteries, the lock must be packed in your carry-on luggage and should not be placed in checked baggage.
