# Lock/unlock records
The "Lock/Unlock records" action is used to prevent operations from being executed on specific records. It's useful when you want certain records to remain unchanged by bulk operations or automated rules.
### Record lock status
The lock status is indicated by a lock icon in the "Locked" column.
### Locking/Unlocking Records
There's no need to exclude already locked records when locking, or unlocked records when unlocking, as the system will automatically detect the status and execute accordingly.
1. Select the records you wish to lock or unlock using the checkboxes in the data table.
2. Under actions, click "Lock/Unlock Records".
3. Two options will appear:
* Choose "Lock" to prevent records from being modified.
* Choose "Unlock" to release records from lock
4. Click "Apply" to submit your changes.
