    First: the battery box is installed in the door, by the hinge side, open the door to more than 90 degrees, check the upper position of the door leaf (behind pressing the doorbell switch, because the doorbell wire is very short), there will be a battery box, take it out and put it into the battery (you can take it out).

    Second: Siamese cat's eye doorbell, as the name suggests, the battery box is just behind the cat's eye.

    That is, behind the door mirror, there is a small cylinder with a clip, which can be taken down when pressed. Then put the battery inside.

It should be noted that it is the master's bottom line, whether it is sent by the shopping mall, and the key seal, which should be opened in person, and the main key should be kept by itself after opening, and the secondary key should be used by the master to install the lock. (Note: There are 2 sets of keys when the lock is bought, one is used to install the door, and one is used to install the lock for their own use, as long as the main key is used once, the secondary key can not be opened, and it is invalid.)
