Using this cable key lock is easy. Just wrap the cable around the object you want to secure and insert the key to lock it. When unlocking, simply turn the key. Make sure to keep the key in a safe place. For maintenance, wipe the lock and cable with a dry cloth regularly to prevent rust. Avoid exposing it to extreme weather conditions for long periods. If the lock becomes difficult to turn, a small amount of graphite powder can be used to lubricate it.
