Secure your bicycle with this advanced alarm cable lock. It features dual unlocking methods: use the 4-digit password (with 256 possible combinations) or the included remote control for keyless convenience. The lock emits a powerful 110dB alarm if the steel cable is cut, the lock body is tampered with, or the password is entered incorrectly three times. One remote can control multiple locks, and a single lock can be paired with up to 8 remotes. Built for durability, it has an IP55 waterproof rating and operates in temperatures from -10°C to +60°C. The remote has a range of approximately 40 meters (131 ft). The lock is powered by 3 AAA batteries (not included), providing about 3 months of standby life. The remote uses a built-in CR2032 battery with a 3-5 year standby life.
