First, remove the mechanical key. Then, use a screwdriver to gently pry open the key along the middle seam. If you don't have a screwdriver, you can use scissors or a knife, but proceed slowly and carefully. Next, peel off the round sticker, remove the old battery, and replace it with a new one. Finally, firmly press the back cover back into place. Below is some relevant information about the Axela key: 1. Basic components of the Axela key: The system mainly consists of two parts: the transmitter and the receiver. Transmitter: Composed of a transmission switch, transmission antenna (keypad), integrated circuit, etc. It contains an identification code storage circuit and an amplitude modulation circuit, with a button-type lithium battery installed on the opposite side of the circuit. 2. The transmission frequency is selected according to the radio standards of the country of use. Each time the transmission switch is pressed, a signal is sent. Receiver: After the transmitter sends the identification code via shortwave modulation, it is received by the car's shortwave antenna and processed through a distributor into the shortwave high-frequency amplification processor of the receiver's electronic control unit for demodulation. The demodulated identification code is then compared; if it is the correct code, it is input into the control circuit to activate the actuator.
