Through experience I have found that there are some rules to using the panel. First, make sure you firmly press each number. Second, do not get in a hurry when entering numbers, the unit gets confused. If it does not work the first time count to 10 and try again. If it did not unlock the first time you need to wait until the panel lights go out. I know, that is difficult in the daytime. Counting to 10 helps. The lights going out indicates that the panel is ready for another try. The panel does not like rapidly entered numbers or long strings. For example, if you have a four digit code and it doesn't work the first time and you then quickly reenter the number (before the lights go out) the unit sees that as an eight digit number. If I am unsure as to whether or not my panel is working I wait until dark to try it so that I can see if it lights up when I press the numbers. No lights, no power. You can do a reset on the panel by unplugging it. At each end of the panel there are removable covers that slide sideways. I recommend a small screwdriver as a pry tool. Behind those covers are two screws removal of which will remove the panel. If you pull out the wire you will find in in-line plug. Unplug the unit for 30-60 seconds and the plug it back in. The panel should start working. If not, you have problems elsewhere, such as in the control unit. It took me two weeks and two visits to the dealership to learn all of these rules. I did all of my experiementation in the garage with the garage lights out so I could see what the panel lights were doing.
