Using your Kryptonite Kryptolok 610 lock is easy. First, unfold the lock and wrap it around the object you want to secure. Then, insert the key and turn it to lock. To unlock, just insert the key again and turn it the other way. When not in use, you can use the easy - to - install transport bracket to carry the lock around. For maintenance, keep the lock dry to prevent rust. If the key gets stuck, you can apply a small amount of graphite powder to the keyhole. Make sure to always keep your keys in a safe place, as this lock is part of the Key Safe Program.
