# Locks

Locks prevent certain information from being modified during automatic inventory feedback. These locks are activated when a manual modification has been made.

***

## Lock a field

To lock a field, you need to modify the data of this field manually.

When a field is modified manually, an icon <i class="fa-lock-keyhole">:lock-keyhole:</i> appears next to the title :

## Unlock a field

* To unlock a field, go to the GLPI object on which the lock is located
* In the lock tab, click on the checkbox of the item to unlock
* Click on **`Actions`**
* Then **`Delete permanently`**
* And **`Post`**

The padlock is no longer present on the field and can now be modified by the automatic inventory.

All changes will be stored in the **historical** tab.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.glpi-project.org/documentation/modules/assets/tabs/locks.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
