I have encountered this situation, at that time, I found some high-grade engine oil, got some in, and then slowly turned the key back and forth, while turning, pay attention to lifting the door up as much as possible, and slowly opened; After opening it, I checked it carefully, and it turned out that there was a problem with the spring above the door, and I also added some oil to it, and it was good to get it a few times.
How to lock the security door, and if there is a key outside, it can't be opened? The anti-theft door is in the house, lock the fixed lock of the front Kai, there is a key outside, and it cannot be opened, and the fixed lock can only be opened in the inner lock, and then the door can be opened.
Haha,Panpan has the manual for the security door.。
