# Recording and Modifying Cylinders

Help for adding or modifying a cylinder.

## Recording a Cylinder

In portier VISION, each cylinder has its own record.

In the **MANAGEMENT / CYLINDERS** module, click the **ADD RECORD** button in the toolbar. The **CYLINDER** window opens.

![In the upper section "KEYS FOR CYLINDER", enter the relevant cylinder data. In the Installation Data section, you specify exactly where the cylinder has been installed.](https://staticfiles.gleap.io/g/aYbrq38TJDwMpTZ43wPS38IwWL18jV7B3ow04anzXyLBKfbuBtTq0fCBG6C8XOBVwkEkmvOUhEj.png)

In the upper section "KEYS FOR CYLINDER", enter the relevant cylinder data. In the **Installation Data** section, you specify exactly where the cylinder has been installed.

Save the entered data by clicking the **SAVE** button.

![Close the CYLINDER window by clicking the BACK button.](https://staticfiles.gleap.io/g/wj1EV0jwBNODLM8flA4MaFS1nXhRMoSaJv4PW2EmNpZ6lKeiHY5CWn4e0tXpskoMRlaEaS2hi4o.png)

Close the **CYLINDER** window by clicking the **BACK** button.

![The cylinder is now available. In the Keys section, portier creates a key record and makes available exactly the number of copies (Exemplare) you entered under Total quantity.](https://staticfiles.gleap.io/g/7f800BqQVFUcKQYxNOsayRZGgMqUovvjNdZ8FgejaopvpA69m352G8eSN9z6xDpzAdunUMcgoVt.png)

The cylinder is now available. In the **Keys** section, portier creates a key record and makes available exactly the number of copies (**Exemplare**) you entered under **Total quantity**.

The link between cylinder and key is established via the key number, also called the locking number.

**Important: this key number can never be changed.**

## How to Modify a Cylinder

In the **MANAGEMENT / CYLINDERS** module, enter the data of the cylinder you are looking for in the **CYLINDERS** tab, for example the key number, and press ENTER. The cylinder is displayed.

![Double-click the cylinder to open the CYLINDER window. There you find the Installation Data tab. Use it to edit the cylinder details.](https://staticfiles.gleap.io/g/1UpddPAGMpsSyD3pfy8cU2moZSBASAugxpf5AZ6E3Ew09ztUkvwPXJ7V40IottJahDtwMnOyiXd.png)

Double-click the cylinder to open the **CYLINDER** window. There you find the **Installation Data** tab. Use it to edit the cylinder details.

Save the changed cylinder data by clicking the **SAVE** button.

![Save the changed cylinder data by clicking the SAVE button.](https://staticfiles.gleap.io/g/2L0S90fAWM2cUarCOfvQbeLomTzvZUIdsBfV0gtmTnu0Z2zTnvmBCnOZnZ0LRQJb06MtnqcWskY.png)

## Important Note

Key details can no longer be changed in the cylinder screen after the initial entry. In **MANAGEMENT / KEYS** you can edit the key details, provided you have the corresponding permissions. Only the key number itself can never be changed after initial entry.

## Note on Re-Importing

If the locking system is imported again later, portier does not update a system that already exists. The SCHLUESSELART and SCHLIESSUNGSART fields are not refreshed on re-import either. Cylinders you entered by hand therefore stay as you created them.
