How keys, locks, and rings work together as a single keyed system.
A barrel lock isn't a single component — it's a system. The key, the lock body, and the meter ring or collar all have to match dimensionally for the system to function in the field.
Most utility districts standardize on a single keying within their territory. Crews carry one key per service type and that key opens every lock in inventory.
When a lock is removed for service, it should be replaced — not reused — if the body shows wear, corrosion, or impact damage.
