[DiCody]

The method for replacing the battery of a Nissan Patrol remote key is as follows: 1. Place the Nissan Patrol remote key with the logo facing upward. Use your left thumb to pry upward at the middle seam of the remote key to open one end of the battery cover, exposing the battery. 2. Insert a toothpick into the notch at the edge of the battery and remove the battery. 3. Insert the new battery into the battery slot, close the battery cover, and gently press the cover to ensure it is securely fastened. The components of the car remote key system are as follows: 1. Transmitter: Consists of a transmission switch, transmission antenna (keypad), integrated circuit, etc. 2. Receiver: After the transmitter sends the identification code via shortwave modulation, the car's shortwave antenna receives it and uses a distributor to enter the shortwave high-frequency amplification processor of the receiver's electronic control unit for demodulation. The demodulated identification code is then compared; if the code is correct, it is input into the control circuit to activate the actuator.
