Using your Kryptonite Kryptolok Series 2 U - lock is easy. First, open the U - lock with one of the provided stainless steel keys. Wrap the 4’ KryptoFlex double loop cable around your front wheel or any accessory you want to secure and then insert the U - lock through the bike frame and the cable. Close the U - lock and make sure it's locked tightly. When carrying it, use the EZ Mount transportation system for a convenient way to attach it to your bike. As for maintenance, keep it clean and dry. The protective vinyl coating helps prevent rust, but if you notice any signs of wear, you can clean it with a mild soap and water. Make sure the dustcover is always in place to protect the cylinder. Keep your keys in a safe place and use the Key Safe Program if needed. Avoid exposing the lock to extreme temperatures or chemicals, as this may damage the lock's components.
