## Unlock the Lock

### The Lock Is NOT Linked

When it is not linked to a relay, it will display on the app homepage.

You can directly tap **Unlock** or tap **Unlock** on its monitoring page.

![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-1755684588344.png) ![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-C15J7AJ6.png)

![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-1756117198330.png)

### The Lock is Linked

After the lock is linked to a door phone relay, it is no longer operated independently within SmartPlus.

Instead, the door phone becomes the access control device. Any successful unlock action on the door phone triggers the configured relay, which simultaneously unlocks the linked smart lock.

#### Unlock on the SmartPlus Homepage

You can tap ![_scroll_external/attachments/image2022-8-12_15-22-37-58ef6892a7af45b19faae4e1325f1cdcf345b065c58eff29a4a0514a8e24882f.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/how-to-open-yale-smart-lock-on-your-smartplus-app-image-cdbzous7.png) to open the door phone’s relay. At the same time, the akubela lock is unlocked.

![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-1755739370254.png)

#### **Unlock on the Calling and Monitoring Page**

Tap **Unlock** on the Calling and Monitoring page to unlock the akubela lock.

You can switch to the lock’s monitor view by tapping **Switch Monitor**.

#### Unlock the Linked Lock via the Door Phone

Once the lock is linked to a door phone relay, it can be unlocked **through the door phone**. The door phone authenticates the user using its supported access methods and then unlocks the linked smart lock.

Please click the following links to view how to set up specific access methods:

- [Unlock by Facial Recognition](https://knowledge.akuvox.com/docs/akuvox-smartplus-app-user-guide#open-doors-with-face-id);
- [Unlock by NFC](https://knowledge.akuvox.com/docs/akuvox-smartplus-app-user-guide#open-doors-with-nfc);
- [Unlock by Bluetooth](https://knowledge.akuvox.com/docs/akuvox-smartplus-app-user-guide#open-doors-with-bluetooth);
- [Unlock by PIN Code](https://knowledge.akuvox.com/docs/akuvox-smartplus-app-user-guide#open-doors-with-a-pin-code);
- [Unlock by RF Cards](https://knowledge.akuvox.com/docs/akuvox-smartplus-app-user-guide#open-doors-with-an-rf-card).

> [!NOTE]
> Note
> 
> - Facial recognition, PIN, NFC, Bluetooth, or card authentication are performed by the door phone, not by the smart lock.
> - The access methods supported by the device vary by model. For example, some models do not support opening doors via Bluetooth.
> - If you want to learn what access methods are supported by your device, please refer to the [product datasheet](https://www.akuvox.com/supportDownloadCenter) or admin guide.

### Sync PIN to Open Locks

When the app’s version is 7.32.2(iOS)/7.32.0002(Android) or higher, the added PIN will be automatically synchronized to the lock for door access.

You can add or modify the PIN on the **Me > Authorization > Door Release PIN** page. It should be 6 to 8 digits for unlocking the SL50.
