? 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.

? A deleted User access code is accepted—unlocks the lock.
A user with the identical access code exists in another User Group.
Ensure that duplicate access codes do not exist across Groups.
? When a valid access code is entered, the lock unlocks but it
alternately flashes the green and red lights during the
unlock time period instead of just the green light.
This is the low battery indicator. The lock batteries are weakening;
however, the lock will continue to operate for up to 2 000 openings
after the first warning.
Replace all four AA alkaline batteries with new batteries.
? No sound is heard from the lock when access codes are
entered—when a pushbutton is pressed or access is granted.
The lock buzzer sound is set to off.
Program the lock buzzer sound to loud (command code 702) or soft
command code 701) as desired.
