Situation 7
The functioning has been normal, but suddenly, the latch bolt locks
up, and the turn piece inside cannot be rotated, not even with the
key.
The door can be locked normally, but three short
beeps are heard and the door would not unlock when the
user code is entered and the programming button is pressed.
While the door is closed, you hear the latch bolt
coming out when you press the programming button to lock
the door; however, three short beeps are emitted.
Conversely, while the door is open, no beeps are emitted
when locking the latch bolt.
