1. Try one by one. The password is generally three digits between 000 and 999. The time required for each password attempt is three seconds. The time required for all possible attempts is 50 minutes.
2. Find the gap. There is a gap under the luggage compartment roller. You can adjust the gap to the same direction, and then turn the roller to the left. If it is not the correct password, continue to turn to the left for one space.
3. Manual unlocking. Turn each roller from 0 to 9 once. When the number is correct, the roller will be relatively loose. （HangLiXiangMiMaWangLeZenMeBan）
