How to remove the key sign on a washing machine

Discover why your Samsung washing machine shows a key sign and learn how to safely unlock the door using built-in safety features, Child Lock settings, and emergency drainage methods.

The key sign on your Samsung washing machine indicates that the door is locked for safety reasons. This feature prevents accidental opening during active cycles, when the drum is hot, or when water remains inside. Follow these steps to resolve the issue safely.

1. Why does the washing machine show a key sign?

- The wash cycle is still running: The door remains locked until the selected cycle finishes completely.

- Hot water or steam remains inside the drum: The door stays locked temporarily to prevent accidental injury.

- Child Lock is enabled: Some models automatically lock the door when Child Lock is activated.

2. How to check if the wash cycle is complete

1. Check the wash cycle timer to confirm if the cycle has finished.
2. Verify that all water has drained from the drum.
3. Press Start/Pause to stop the cycle manually if needed.
4. Wait a few moments for the door lock mechanism to release.
5. Check if the door lock indicator turns off.

The door may remain locked briefly even after the cycle ends.

3. How to check if Child Lock is enabled

1. Locate the Child Lock buttons on the control panel.
2. Press and hold both Child Lock buttons.
3. Wait for the Child Lock icon to flash.
4. Press and hold the buttons again to disable Child Lock.
5. Check if the key sign disappears from the display.

Button locations and Child Lock controls may vary depending on the model.

6. When to contact Samsung Support

Contact Samsung Support if:
