    Is it that the second pass of the key lock is very stuck, or the lock point does not pop up at all? If it is very stuck, it is good to lubricate it directly with graphite powder or pencil foam, if the lock point can not pop out or pop up a little, then you have to check whether the position of the side lock point and the position of the lock body is faulty, it is best to let the manufacturer's after-sales personnel come to see, they solved it at once.
