Anonymous users2024-01-22You first look for where the battery box is, some are on the back of the door, some are on the side of the door, and very few are on the door frame or externally! Some have plastic covers, some have metal covers, some are clamped and some are screwed, and some of the colors are different from the color of the door, and some are similar to the color of the door, which is a bit difficult to find. You look at it and install it again, the battery must be installed on the door.

Your security door is outside, lift the lock handle up, and you'll be fully safe.
It could be that the spring of the lock cylinder is broken, or something inside the cylinder is stuck. >>>More
Try to change a spare key, I have encountered this situation a few times, and the door is opened when I change a key that has not been demagnetized.
The lock cylinder is misplaced, so remove it for repair.
Don't be able to lubricate the oil, because the lubricating oil is easy to get dust on the key, and it is easy to get into the lock cylinder if you open the door again. It is best to grind with a pencil or have soap. If you still can't open it, you can only find a lock picking company.
