How can I remove the shackle on my Master Lock Bluetooth lockbox using my Primary Code
- Press and hold down
the circle button, also known as the Reset button.

- While holding down
on the circle button, press the first digit of your Primary Code and
QUICKLY release both buttons at the same time.
- Continue entering the
rest of your Primary Code. Do NOT press the first digit again, as you
have already entered it.
- The inner locking
mechanism will release the shackle (you will hear a click) and the reset
button light will turn green.
- Pull up to remove
the shackle within the timeframe of your auto-relock delay.
