The OnGuard Akita Key Cable Lock is one tough fighting dog. The barrel lock is engineered to resist all the angles would-be thieves use when trying to bike-nap your baby. The cable is 20mm, as in good luck trying to cut through this in under two hours, and it comes with 5 keys...one of them even lights up for all your nighttime back-alley unlocking.
