How often should the key battery be changed, and how often should the battery of a car key be change

Key batteries should not be counted by the time of use, but by the frequency of use. For example, civil servants commute to and from work, they switch on and off twice a day, and if they are outside to run business, they switch on and off 20 times a day, and it will definitely take a short time to run business. For a normal family car, one key is basically no problem for more than 1 and a half years, and if the two keys are used alternately, it may be 3-4 years.

Smart key slightly.

If you use it more frequently, you can change it once every 2 years, and if you use it regularly, you can change it every 3 to 4 years.

I'm glad to answer for you and have a nice ride! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, this is based on the frequency of time, and it should be no problem to use it for 4 years. Have a great trip. If I can help you, please set it to, thank you!

Hello, this can generally be used for about 2 years, mainly depending on how much you use! I hope it helps you and I wish you a happy car! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

The car key battery is not a concept of how often to replace, when the control distance of the car key is less than half of the maximum remote control distance or less than five to six meters, the battery should be replaced in time. No matter how long it takes, of course.

Hello this rider: It is generally replaced in 3 years.

Key battery replacement needs to be situational! If you feel that the sensing distance has become shorter or sometimes you can't sense it! The battery needs to be replaced!

The system is mainly composed of two parts: a transmitter and a receiver.

Transmitter: It is composed of a transmitter switch, a transmitter antenna (key board), an integrated circuit, etc. It contains a memory loop and an amplitude modulation modulation loop, and a button-type lithium battery is installed on the opposite side of the circuit.

The transmitting frequency is selected according to the radio standard of the country of use, and the transmitter switch transmits the signal once every time the button is pressed.

Receiver: After the transmitter uses short-wave modulation to send out identification**, it is received through the short-wave antenna of the car, and the short-wave high-frequency amplification processor that enters the electronic control unit of the receiver is used to demodulate and compare with the identification ** of the demodulator; If it is correct**, enter the control circuit and make the actuator work.

Whether the car remote control key is used for a long time is mainly determined by the frequency of the car owner's usual use of the car key. The more you use a battery, the more power it consumes.

Signs of car keys before they run out of power:
