Using this lock is a breeze. First, unfold the lock and wrap it around the object you want to secure, like your bike frame and a bike rack. Then, insert the key and turn it to lock. Remember to keep the keys in a safe place. When not in use, you can use the transport bracket to carry it easily. To maintain the lock, keep it dry. If it gets wet, dry it off with a cloth. Avoid exposing it to extreme temperatures for long periods. If the lock becomes difficult to turn, you can use a little bit of graphite powder to lubricate it.
