The problem of the door. Let's see if it's a lock problem, and if so, put some oil. If you don't have it, use cooking oil.
After the security door combination lock is unlocked. 15 seconds interval is required. to be locked. This is a procedural regulation, and the procedure can be modified. Set the fraction to zero seconds. Later, you can lock it immediately after unlocking.
Turn the lock tab out and you'll be fine, because your door is not well sealed.
The door seems to have a sound, and most of the time the door is deformed. >>>More
