The padlock is an indication that the On Screen Display is locked. You can also lock or unlock the OSD by pushing the Menu button for over 15 seconds.

SOURCE: padlock appears on screen

I have this monitor,got it used at the goodwill, padlock problem and the control buttons (eccept for power) did not work. I tried every solution posted with no success. Then I got brave, I dove into the problem. 1) remove base, four phillips head screws. 2) remove the back, five phillips head screws. one in each corner and one behind the base mount, thus the need to remove the base. 3) carefully pry off the back, it snaps on, so take your time. I found a butter knife to be very helpfull. 4) The buttons are sodered to an electrical board whitch is snapped into place so carefully pry up from one side,again I used a butter knife. The wires are sodered to the board, they do not unplug. 5) Using a can of air, blow into each button and trying to clean out the inside them. I'm sure they should probably be replaced but we do what we can. 6) Put it all back together. 7) plug it in and connect it to computer. start working the buttons, at first I thought it was a lost cause but after about a minute I was able to get into the menue, scroll down using the arrow buttons and turn the lock off. A $300 monitor for 40 bucks. I hope this message gets to you before you give up. GOOD LUCK, GMAN8773

Padlock icon


Many monitors have an on-screen display lock (the padlock icon) that seems to get stuck.
Various suggestions in the links below - the one that seems to work most often is to hold the monitor's menu button down for 15-20 seconds to get the screen menu, then either try unlocking the OSD (On Screen Display) or do a factory reset on the monitor.

Different monitors have slightly different menus, but if it's a Dell monitor you can find the manual below (under Display):

Locked out of thermostate


From the manual:



PROGRAMMABLE KEYPAD LOCK
To prevent tampering with any of your settings or
temperatures, the front panel buttons and the rotary dial can
be locked out, requiring a four digit code to unlock them.
You may use either the default lock code of "0000", or your
own personal number combination (see "Changing The Lock
Code")


LOCKING THE THERMOSTAT: Ensure the rotary dial is in the
RUN position. Press the NEXT button for at least 2 seconds.
The words "ENTER CODE" will appear on the screen, along
with "0000". Press the NEXT button again for at least 2
seconds. A padlock should appear on the screen to confirm
that the thermostat is now locked.


LOCKING THE THERMOSTAT: Ensure the rotary dial is in the
RUN position. Press the NEXT button for at least 2 seconds.
The words "ENTER CODE" will appear on the screen, along
with "0000". Press the NEXT button again for at least 2
seconds. A padlock should appear on the screen to confirm
that the thermostat is now locked.

UNLOCKING THE THERMOSTAT: Ensure the rotary dial is in
the RUN position. A single press of any button should cause
the words "ENTER CODE" to appear on the screen, along
with "0000". If the default code was used to lock the
thermostat, press the NEXT button for at least 2 seconds.
The padlock should disappear from the screen, and the
thermostat should now be unlocked.
If you try to unlock the thermostat by entering a code that is
not correct, a padlock and the digits "88:88" will flash on the
screen and you will have to try again. If a lock code
different from the default was used, this will need to be
entered by using the UP/DOWN buttons, and the NEXT
button to advance to the next digit. Once the correct code is
entered, press the NEXT button for at least 2 seconds and
the thermostat should now be unlocked.


CHANGING THE LOCK CODE: To create your own specific
lock code, first ensure that the rotary dial is in the RUN
position. Press the NEXT button for at least 2 seconds. The
words "ENTER CODE" will appear on the screen, along with
"0000". Now press the HOLD button again for at least 2
seconds. The words "SET CODE" will appear on the screen,
along with "0000".

IF YOU FORGOT YOUR LOCK CODE: You can still unlock the
thermostat by performing the following steps: On the back
of thermostat locate JP1, which is a row of 3 metal pins at
the right edge of the circuit board above the battery tray.
There should be a plastic jumper cap on 2 of the 3 pins
(right or left).


Move the jumper cap so that it is on the opposite 2 pins.
For this change to be recognized, move the Temperature
Mode switch to any other position than its current one.
These steps listed should have changed the lock code back
to the default of "0000". Follow the instructions already
listed in "UNLOCKING THE THERMOSTAT".
