Next-Level Security for Existing Locks

KnoxLock^® Retrofit Cylinders deliver cost-effective accountability for asset protection and access control in locks using many common U.S. standard lock cylinders.

KnoxLock Retrofit Cylinders are highly resistant to dust, dirt, and moisture and are reliable in harsh weather conditions. Ideal for providing rapid access to storage and equipment, these retrofit cylinders offer a convenient way to track access to existing doors, cabinets, padlocks, and potentially other devices requiring a lock core, where a wired access control system is infeasible or cost-prohibitive. Powered by the Knox eKey, the lock requires minimal maintenance, with no batteries to replace or cleaning schedules.
