# ActiveLockExists (/docs/errors/chain/ActiveLockExists)

The destination coldkey already holds a lock with nonzero locked mass on that subnet, so a new or transferred lock cannot be created there. Inspect the `Lock` storage for the (coldkey, netuid, hotkey) triple and wait for the existing lock to unlock or remove it first.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`already_exists`](/docs/errors/already-exists).

## Remediation [#remediation]

The object or state already exists; treat the goal as met or pick a different target

The same explanation is available in the terminal: `btcli explain ActiveLockExists`.
