okay I can take a stab at it . We can try 3 different ways. If it doent work you will have to call the company and ask for tech support. to help you.
It might be 91 3 times to the right 29 2 times to the left 2 1 time to the right.
first go to zero a few times twice or three times and stop at zero. Now spin it 3 times to the 2 times to the right passing 91 on the third spin stop at 91.
now its on 91 spin 2 times to the left to 29 on the second spin stop at 29
Now turn to the right to the number 2 and try opening.
2nd. try. turn to the number zero t2o or three times. Now from the zero turn left three times to 91 on the third time stop at 91. now its on 91. now turn it 2 times to thr right to number 29. on the second turn stop at 29. now its on 29 now go left to the number 2 and try to open.
3rd. try. turn a few times to zero. now turn to the right until you get to 91. then turn to the left until you get to 29 then turn to the number 2 to the right.
4th try. turn a few times to zero. now turn left until you get to 91, then turn right to 29 then turn left and stop at number 2. Let me know if any of these work. if not you will have to call the manufacturer, do you have their number if not tell me the company.
