I Changed or Deleted a code, but the old code still unlocks
the door
Remember there are a total of 6 User Codes for the KE-
265. Make sure you changed the desired code. If you
changed the Master Code, the other User Codes will still
work. If in doubt, it is recommended you reprogram the
master code and delete all 5 user codes. Then program
any new user codes. (See System Programming page 14)
The Keypad beeps normally but the door does not unlock
For a new installation:
1) Check the specifications of your power supply and
locking device. (See Input Requirements page 3.)
Note: If you are connecting 12VDC, make the
connections to "DC IN/OUT" instead of "12-24V
AC/DC IN" (see Circuit Board Layout - Page 23).
Make sure polarity is correct.
2) Test the wiring hookup to the primary locking device
(the device connected to User Code 1, 2 Unlock). On the
control module circuit board, locate and momentarily short
the screws for "REMOTE"(See page 23). This will activate
the output (same as if you enter a valid programmed code
at the Keypad).
If this test does not activate the lock, check the lock
wiring (see Typical Wiring Diagrams - page 24). If
your wiring is correct, check the KE-265 relay
settings (see Setting Relay Options - page 10).
If this test does activate the output (you should
hear the relay click and the locking device should
unlock), reprogram the Master Code and User
Codes. Review Overview of System Code
Programming (Page 14).

Remember that all six codes have to be different
from each. It is also important not to let more than
5 seconds elapse between button presses or the
system will reset and you will have to start over.
For an existing Installation:
There are typically two reasons for code loss: static or
inductive kickback. There is no way to determine if the
system has been affected by either of these, however, you
can reprogram the system codes as described in User
Code Programming. It is very important the system is
properly grounded and the MOV has been installed,
otherwise static and code loss may be an ongoing
problem.
The Door opens with the first press on the Keypad
If the unit has just been installed, check the CCTV jumper
(see Setting Relay Options – Page 10). If you do not have
a CCTV connected to the KE-265, make sure the CCTV
jumper is NOT installed across the1
st and 2 nd pins or the
2 nd and 3 rd pins.

Interrupted Power - First check your power supply to see
that power has not been cut off. Using a voltmeter, check
the incoming voltage on terminal strip “B” (12-24V AC/DC
IN). If the voltage reads low, the electric locking device
may be drawing too much current. To test, remove the
wires to the device and recheck the voltage. If the voltage
now reads normal, check the current draw of the locking
device and make sure it falls within the system
specifications (see Input Requirements – page 3).
Blown Fuse - Check the fuse on the circuit board. The
purpose is to protect the power supply and circuitry. If
your locking device is drawing too much current or there is
a short, the fuse will blow. Replace with a 2 amp slo blo
only. A spare fuse is provided in the spare parts kit.
Although the fuse may appear intact, it is best to check
with a voltmeter.
