Keeper 585 keyed chain lock

Updated 2026-09-05

This lightweight chain lock provides 2.7 ft of reach, making it a portable and effective option for secondary security or low-risk environments. The 5mm four-sided chain links are made from manganese steel, offering a reliable deterrent against opportunistic theft. Its compact size allows it to be carried easily in a small bag.

The integrated keyed cylinder is designed with a disc-style mechanism to resist picking and drilling. The lock head is permanently attached to the chain, ensuring there are no loose parts to lose. This streamlined design makes the locking process fast and efficient for riders on the go.

To protect the bicycle's finish, the chain is wrapped in a rugged fabric sleeve. This sleeve is weather-resistant and helps to dampen noise while riding. Two stainless steel keys are provided, featuring an ergonomic design that makes them easy to use even in cold weather or with limited dexterity.
