Using this Keeper STD U - Lock with 4ft Cable is a breeze. First, use the U - lock to secure your bike frame to a fixed object like a bike rack. The double deadbolt design ensures a tight and secure fit. Then, you can use the 4 - foot cable to lock your front wheel or other small accessories. To unlock, simply insert one of the ergonomic stainless - steel keys into the disc - style cylinder with the center keyway. When it comes to maintenance, keep the lock clean and dry. Avoid exposing it to extreme weather conditions for long periods. If the lock seems a bit stiff, you can use a small amount of graphite powder to lubricate the keyway. Remember to enroll in the Key Safe Program for peace of mind in case you lose your keys.
