- Locate the programming port on the Dormakaba lock. This is typically a mini USB port.
- Connect the mini USB cable from the Emergency Lock Power Supply into the programming port of the lock.

6. Maintenance
After successfully gaining access to a room using the emergency power supply, it is crucial to change the batteries in the Dormakaba lock immediately to restore normal operation and prevent future access issues.
For the emergency power supply itself, ensure it is stored in a dry, cool place. Check its internal batteries periodically and replace them as needed to ensure the device is ready for use when an emergency arises.
7. Troubleshooting
- Device not powering the lock: Ensure the mini USB cable is securely connected to both the power supply and the lock's programming port. Verify that the internal batteries of the emergency power supply are charged and correctly inserted.
- Lock motor does not cycle: If the lock motor does not make a chattering noise after connecting the power supply, double-check the connection. Confirm the lock model is listed under compatible devices (Section 2). Remember, this device is not compatible with locks programmed with the Aurora software platform.
- Keycard not working after power supply connection: Ensure you are using a valid keycard for that specific lock. The power supply only provides temporary power; it does not re-program the lock or validate invalid keycards.
