# HotKeyAlreadyRegisteredInSubNet (/docs/errors/chain/HotKeyAlreadyRegisteredInSubNet)

A registration or hotkey swap targeted a hotkey that already holds a UID on the subnet (or, for a swap without a netuid, on any subnet). Check the `Uids` storage for the (netuid, hotkey) pair or `btcli wallet overview`; use a different hotkey or netuid.

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 HotKeyAlreadyRegisteredInSubNet`.
