To enter your own security code you will need to follow the steps listed below:
After opening the electronic safe (with the preset factory code of 1 - 5 - 9 - #) locate the small red button on the inside of the door near the hinge.
Press the red button and then release it, you will hear a beep. The yellow light on the faceplate will be activated and will stay on for a period of time that should allow you to enter your code. You can only enter your code while the yellow light is on.
With the door open and the yellow light on, enter your own personal security code, which can be 3 - 8 digits long, and confirm your new code by pressing the " * " symbol on the electronic touch pad. Before you close the door, try the new security code to make sure the lock releases the handle so you can turn it and retract the live action bolts.
