How to Open a BYD Car Key?
2 Answers
First, press the button on the BYD car key, then pull out the mechanical key. Next, insert a screwdriver along the gap of the key shell to pry open the car key. Pressing the button once executes the action once. If the button is held down, the action will not repeat. To execute again, release and press the button once more. Pressing the "LOCK" button will cause all door lock motors to perform a locking action simultaneously, and the turn signal will flash once. When the vehicle is in anti-theft mode, pressing the "LOCK" button will produce a long beep and the turn signal will flash. Pressing it again will re-enter the vehicle search mode.
I remember disassembling a BYD car key is quite simple, I've done it a few times myself, mainly to replace the battery. Usually, there's a small gap on the side of the key, and you can gently pry it open with a fingernail or a bank card. Avoid using too sharp tools to prevent scratching the casing. Most BYD remote keys are designed with plastic clips, so once you pry one side open, the entire casing can be separated. Inside, there's usually a coin battery, like the CR2032 model. After replacing the battery, align the clips and press them back together to finish. However, keys for different models like the Tang or Song might be slightly different, so it's best to check the owner's manual to confirm the structure before disassembling. After reassembly, remember to check if the buttons are responsive to prevent remote failure due to improper assembly. If you disassemble frequently, keeping the key dry can extend its lifespan. In short, doing it yourself saves time and money, but be careful not to lose any small parts.
