One, how to replace the battery for an electronic door lock
1. Press the battery cover upwards to remove it. It may require some force. Remove all old batteries and replace them with new ones. Do not mix new and old batteries. Allow the device to run normally for a few minutes, then touch the battery. If the battery feels noticeably hot, replace it. Continue until the temperature is normal, then replace the battery cover.
2. Some products utilize a single panel design, so when replacing the battery, the entire internal panel needs to be removed and replaced.
3. For some products, the battery is installed at the bottom of the panel, so the screw slots at the bottom of the panel need to be opened with a screwdriver to replace the battery.
Two. What should I do if the battery in the lock is dead?
1、Equipped with a mechanical key
A mechanical key can be inserted for unlocking. In the event of a power outage, the electronic chip cannot function properly, and a mechanical key can be used for unlocking. The disadvantage of this type of lock is that, while most people typically use fingerprints or passwords to unlock doors, few people carry keys.
2、Has an external power outlet.
This method is the best and most comprehensive. This lock also considers potential scenarios such as power failure. Therefore, a USB port is left on the exterior of the lock, allowing it to be connected to power devices such as power banks and laptops to provide power to the password lock. If the password lock loses power, we can connect a power bank to charge it, and then the lock can be opened.
