Frequently Asked Questions
Q: What type of batteries does the smart alarm lock require?
A: The lock requires 3 × AAA batteries, which are not included in the package. With regular standby use, a fresh set of batteries can last over 8 months. The lock also features a low battery indicator so you'll know when it's time to replace them.
Q: Is this password alarm lock suitable for outdoor use in rainy conditions?
A: Yes! This lock carries an IP44 waterproof rating, making it suitable for both indoor and outdoor environments. It can handle rain, splashing water, and operates in temperatures ranging from -20°C to +60°C, so it's reliable year-round.
Q: How does the anti-theft alarm get triggered?
A: The alarm activates instantly in three scenarios: (1) when the lock is shaken or physically moved, (2) when the steel rope is cut or lock screws are tampered with, and (3) when an incorrect password is entered three times in a row. The 110dB siren is extremely loud and effective at deterring theft.
Q: Can I use this lock on items other than bicycles?
A: Absolutely. While it's ideal as a bicycle alarm lock, the steel rope and alarm system work great for motorcycles, gates, storage units, gym lockers, strollers, and more — anywhere you need a compact, keyless security solution.
