The lock heart is good, and it can t be opened as soon as it is installed, what is the situation?

The lock heart is good, and the door can not be opened when it is installed, which is caused by the deviation of the fixed position, which needs to have a certain degree of relaxation, and it is not good to make it too tight.

The lock core is good, and it can't be opened once it is installed - there are two situations: one is that the lock core itself is not matched well when it is installed. Second, it is possible that the relative size between the lock and the door is not suitable.

The lock cylinder is easy to make, and after it is safe, it may still be a screw or a screw, or the lock cylinder or circlip or something like that is turned over and stuck, so it is not easy to use, and then check and check.

If you can't open the door after installing it, I think the lock and the lock cylinder are not properly assembled, so they can't be opened.

If you can't open the door as soon as you install it, this should be your form of problem, so it may not be able to install this in Tsinghua, it may be that your lock cylinder is not so well matched.

You may have put the cylinder upside down. Causing locks and not being able to open the door. You can ask a master to come to the door to pick the lock.

If this happens, it should be caused by the misalignment of the lock core and the lock when the door is installed.

In the case of what you said, it should generally be installed in the wrong position, so after it is installed, it is stuck.

The reason why the lock cylinder can't be opened as soon as the door is installed is because the door frame is sinking.

If the lock cylinder is good, it should be because the lock cylinder does not match the external door lock.

If the door lock can't be opened as soon as it is installed, it means that you can't install it or your key can't be matched.

It's just good, what happens when you can't open the door if you want to install it? If the mobile phone is good, it can't be opened as soon as it is installed, and it should be that this lock cylinder does not match this. What does it mean to match the eyes, please take a look at it with a professional.

If this kind of lock cylinder is good, then the installation may not be right, you can find a professional maintenance worker.

This condition is generally due to wear and tear.

As a result, the correct angle cannot be guaranteed after installation.

If this happens, it is recommended that you check if it is because the lock is stuck.

In this case, the deadbolt of your lock may not work well in some places.
