It is very likely that your saber is in button lock mode. This can happen as the color change mode and the button lock mode are accessed with the same 3 taps just with different buttons. If your saber is on and won't turn off, simply quick press the AUX (second button) on the saber hilt 3 times. You will hear a beep sound indicating you are now out of button lock mode and you should be able to turn the saber off. Please reach out to us on our contact us page if you need further assistance.
