The steps to replace the remote key battery of BYD F0 are: 1. Remove the mechanical key; 2. Use a flat-head screwdriver to pry open a small gap from the side of the key, then continue to pry along the gap; 3. Use the flat-head screwdriver to remove the old battery, insert the new battery with the positive side facing down, reinstall the circuit board, align the key cover, and press firmly with your hand to complete the process. Additional information: The car smart key is a common keyless entry system, also known as an intelligent key system. It consists of a transmitter, a remote central locking control module, a driving authorization system control module (three receivers), and related wiring harnesses that form the control system.
I've been driving my BYD F0 for six or seven years, and changing the battery is a common operation. You'll need to prepare a 10mm wrench and locate the battery position in the engine compartment. Remember to always disconnect the black negative cable first, then the red positive cable—getting the order wrong could cause a short circuit and burn out the wiring. Next, remove the screws securing the hold-down plate and take out the old battery. When installing the new battery, make sure it's positioned correctly, and avoid letting the terminals touch any metal parts of the car body. After securing the hold-down plate, connect the positive terminal first, followed by the negative. For the battery model, choose a 36B20R, 45Ah maintenance-free type, which typically costs around two to three hundred yuan. After installation, test the car to ensure smooth starting, and note that the windows and radio may need to be reset.
