Set Time Key
This step uses the DS1904 or DS1994 to set the real time of the lock
Tip: Other than DS1904/1994 real time key, the DS1977 program key can also set the time of the lock. But program key
will cause time delay since programming the mission key and programming the lock will take time. We recommend using
the DS 1904/1994 real time key if the programming process takes more than 3 minutes. To set the time, snap the program
key into the encoder, press the “Issue Key” button, and then press the program key to the lock until it beeps twice to set
the time.
Get Information Key
Get Information mission is a useful tool to retrieve the existing lock information, such as: Key list, lock time, Time
Setting, lock ID, or Batteries voltage. To get the lock information, snap the program key into the encoder, press the “Issue
Key” button, and then press the program key to the lock. The lock will make a series of quick beeps, and when it is done it
will do two final beeps; remove the program key and snap it into the encoder. Press the “Read Key” button to read the
information.
