How to change the battery of smart lock fingerprint lock How to change the battery of smart lock fingerprint lock
First, how to change the battery of the fingerprint lock?
first step
Find the key in the fingerprint lock, and then we find the keyhole of the fingerprint lock at the bottom. Some of the keyhole of the fingerprint lock is above the handle, depending on different fingerprint locks.
Second step
Insert the key into the keyhole and push it up hard, then the door will open automatically. Because the battery box was changed inside the door, we have to go inside first.
Third step
Use a screwdriver to aim at a screw hole above the other side of the fingerprint lock. This black part is the box containing the battery. Unscrew it.
Fourth step
Then you will find that there are four batteries in it (some fingerprint locks may be eight). And note that it is best to replace all the batteries when replacing them. Don’t mix the old and new batteries to save money, because mixing the old and new batteries will damage the fingerprint lock.

Replace the prepared battery, and pay attention to the battery model. Most fingerprint locks use the No.5 battery, but they also use the No.7 battery, so you should look at the battery used in your own fingerprint lock before buying the battery. Then cover the lid, and the holes in the lid should be aligned with those on the fingerprint lock, otherwise the screws will not be screwed on.
Step 6
Tighten the screws to secure the cover. Finally, when we open the cover of the fingerprint lock outside the door, you will find that the fingerprint lock is on and can be used normally.

1. Old and new batteries cannot be mixed.
In fact, to be blunt, the old battery should be thrown away when it is dead, and it has nothing to do with the new battery. Because the old battery is used at a voltage lower than the standard voltage, it will leak due to the chemical reaction in it, and the liquid in the battery is very corrosive, which is easy to corrode the components of the fingerprint lock circuit board, resulting in poor contact or power failure of the fingerprint lock.
2, the positive and negative poles should be correct
This is actually a relatively simple point. Anyone who has installed a battery knows that the smooth side of the battery is pressed against the spring, and then the protruding point is put into the battery box with a little force. However, some fingerprint lock battery boxes have the capacity of 8 batteries, but only 4 batteries can work normally. This installation requires all four sections to be installed in one place, resulting in a loop. (All left or right, up or down)
3. Remember to check after loading the battery.
Many friends will cover the battery immediately after installing the fingerprint lock battery, and then try to see if the fingerprint lock can be used. If it can be used, it doesn’t matter. Sometimes even the keyboard on the front panel of the fingerprint lock is covered without lighting. In fact, this is very incorrect. After installing the battery, we must let the fingerprint lock run normally for a few minutes, and then touch the newly installed battery. If we can feel obvious burning, it proves that the voltage of the fingerprint lock exceeds the rated voltage of this battery. In other words, this battery is inferior and needs to be replaced with a new battery. Otherwise, this hot battery will soon run out, which is equivalent to the use of old and new batteries together.
