How to unlock a fingerprint lock if it has no power or key
Fingerprint locks generally have emergency power extraction functions. Users can look for them. Some are in the mechanical keyhole, and more are in the lock. On the bottom, some are USB ports and some have two contacts.
However, normally all fingerprint locks have an emergency power-off function. If you look for it, some of them are in the mechanical keyhole, and most of them are under the lock. Take a look, and some of them have two contacts. Yes, some have USB ports. Very easy to find.
Many fingerprint locks have USB charging holes. If the fingerprint lock runs out of power, you only need a power bank or mobile phone to provide power through USB, which can easily drive the fingerprint lock system. . Ta-da, you can replace the original battery after entering the house.
Fingerprint locks are equipped with mechanical keys, which is not only for emergency preparation, but also a mandatory requirement of national standards. So remember to leave a key outside at ordinary times. You can carry it with you or leave it at a neighbor's house or a relative or friend's house.
Fingerprint locks will naturally adapt to this situation during development. If circuit-connecting equipment is added to the fingerprint lock, the price will inevitably increase, and it may not be suitable for power outages.
Nowadays, in addition to the commonly used AA alkaline batteries (very easy to buy), large-capacity rechargeable lithium batteries can also be used, which not only extends the working time, but also cooperates with the low-battery reminder function. It can be replaced or recharged in time to prevent the embarrassing phenomenon of the smart lock running out of power.
In short, prepare emergency keys in advance. Can a fingerprint lock be opened without a battery 2
How to open the door if the electronic door lock is out of power
1. Some smart locks can be emergency charged through an external power supply, such as an external power supply (9V battery or Micro USB connected to the power bank) to temporarily power the system, allowing the user to open the door first, and then replace the battery as soon as possible.
2. You can use the emergency battery box. First install four AA batteries in it, and then insert the emergency battery box into the emergency battery box jack of the password lock. Then open the electronic lock and replace it with the battery in the cabinet door that can be used normally.
3. Most electronic password safes actually have two keys. When the two keys are used at the same time, in this case the electronic lock actually does not use electricity. It can be opened under any circumstances. Open the electronic lock, take out the battery, and then replace it with a new charged battery, so that the electronic lock can be used normally.
Extended information
Since smart locks need to be driven by electricity, they involve power consumption issues. Theoretically speaking, there is a real risk of being unable to return home if there is no power. But as long as smart locks comply with relevant national industry standards, they will basically not be turned away because of a dead battery.
For example, the "GA374-2001 Electronic Anti-theft Lock" standard requires that electronic locks must reserve a mechanical keyhole in case of emergency. Of course, with the advent of smart locks, 90% of users choose not to bring keys because keys can be lost or forgotten. However, as a precaution, it is recommended that users keep an emergency key in the office, car or bag. .
In the "GA 701-2007 General Technical Conditions for Fingerprint Anti-Theft Locks", strict requirements are put forward for the battery and power consumption of smart locks: the operating current of the battery should not be greater than 500Ma, and the operating current in the sleep state should be Not more than 50μA. The battery capacity can ensure that the lock can be opened and closed normally for 3000 times without an undervoltage alarm indication. When an undervoltage alarm indication occurs, it should still be able to ensure normal opening and closing operations for not less than 50 times.

How to open the door if the battery of the password door lock is dead
Mechanical key unlocking: According to the national standard requirements for the smart lock industry, smart locks must be configured The corresponding mechanical key is mainly used for unlocking in emergency situations.
External power bank can provide temporary power supply for unlocking: Each smart lock is equipped with a USB interface on the outside of the door. Under normal circumstances, connecting to a mobile phone power bank can provide temporary power supply to allow the smart lock to work normally. After connecting to the power supply, you can officially use fingerprints, passwords, and cards to unlock, including remote unlocking.
Precautions for installing password door locks
When digging a trench, the depth should be moderate. If it is too deep, it will be difficult to install the password door. If it is too shallow, it will be difficult to install the password door. The code door is loose.
It is necessary to conduct an in-depth inspection of the circuit of the password door. To prevent the password door from short circuit or open circuit.
When installing the sealing strip, be sure not to misalign it and to tightly follow the door frame.
