Possible cause

Solution
?
The lock does not respond at all—no lights and no sound—
when a key is pressed.
➔
1. The connector end of the ribbon cable connecting the front-housing
and the inside-housing is not snugly pushed in.
☞
Push in the connector so that it locks snugly and makes a good
connection.
➔
2. The batteries are missing, the battery connector is not connected,
one or more batteries are placed with the wrong polarity, the batteries
are completely discharged, or non-alkaline batteries are in use.
☞
Correct the above condition and retry.
➔
3. The lock is currently in tamper shut-down mode.
☞
To open the lock, use the mechanical override key, press the hard-wired
remote-unlock switch (if enabled), or simply wait until the tamper
shutdown time period (30 seconds to 15 minutes) has elapsed.
?
A User access or Service access code is not accepted—will not
unlock the lock.
➔
The access code is not programmed into the lock.
☞
Program the lock to add the access code.
?
The lock can be opened without an access code.
➔
The lock is in passage mode.
☞
Program the lock to disable the passage mode (command code 400),
if desired.
