Using this ULAC Bulldog cable lock is easy. First, insert the 2 AAA alkaline batteries into the lock. Then, loop the 120cm cable around your bike frame and the object you want to secure it to, like a bike rack. Use one of the high - security dimple keys to lock it. When you're done, you can use the transportation bracket to carry it or the ULAC velcro to store it neatly. As for maintenance, keep the cable clean and dry to prevent rust. Replace the batteries regularly, especially if the alarm doesn't sound as loudly. Avoid exposing the lock to extreme temperatures. Also, don't force the key into the lock as it may damage the internal mechanism.
