The KryptoFlex 1518 Key Cable is a 6-foot-long, 12mm-thick braided steel cable to be used in low-crime areas or as a secondary security measure. An advanced cylinder provides protection from picking and a dual-sided key makes locking and unlocking a snap. And, Kryptonite's innovative mounting bracket is included for carrying convenience.
Proper locking using a cable plus a U-lock.
Place the U-lock shackle around the pole, your bike frame and through your rear wheel. Loop a cable around your front wheel, bike frame, and onto your U-lock shackle.
Kryptonite's Key Safe Program is an easy way to ensure you always have access to your lock's capabilities. Simply register your key number with Kryptonite and if you lose your keys, your first set of replacement keys are free!
