The hotel key card is locked and rings every 10 second.

The noise of hotel door card lock may be caused by the following reasons:

1. The battery of the lock needs to be replaced: the battery is insufficient, which makes the door lock unable to work normally.

2. The circuit board of the door lock has quality problems: an electronic component is aging or short-circuited, which leads to the failure of the door lock.

3. The door lock is not locked in place: if the door lock is not locked in place, such as the door leaf is not completely closed or the lock core is not completely inserted into the lock core, the lock core will issue a false lock warning to remind the user to close the door leaf again and insert the lock core.

4. False alarm: If an alarm is installed, noise may be generated due to false alarm.

5. Internal mechanical failure of the door lock: failure of internal mechanical components of the door lock, such as damage or deformation of lock core, spring, shaft and other components, may also lead to abnormal sound of the door lock.

If you encounter the noise problem of the door lock, it is recommended to check whether the battery of the door lock needs to be replaced first, and then check whether the door leaf is completely closed and the lock core is completely inserted. If the problem still exists, please contact a professional locksmith for inspection and maintenance.
