This lock is quite simple. To reset the code, press “R” and “C” at the same time. Enter ONLY the first number when the box appears at the bottom, then it will appear once more. Enter ONLY the second number for your new code. This will happen twice more. On the third time, only enter the third number, the fourth time, the fourth number. To enter a code to unlock it, just press/click the button on the screen that coordinates to the number you want. Once the red box turns green, it is unlocked. Press “lock” and it will become red again. (The starting code should be “1111”)
