What is the battery model for the BYD F3 remote key?
2 Answers
The battery model for the BYD F3 remote key is CR1632, and the spare key uses CR2025. Owners can use a flat-head screwdriver to turn clockwise at the bottom of the remote, pry open the remote cover, and then see the battery model. The BYD F3 is a compact 4-door, 5-seater sedan with body dimensions of 4533mm in length, 1705mm in width, and 1490mm in height, with a wheelbase of 2600mm. The BYD F3 is equipped with a 1.5L naturally aspirated engine, delivering a maximum power of 80kW and a maximum torque of 148Nm. It adopts a front-engine, front-wheel-drive layout, with MacPherson strut independent suspension at the front and a torsion beam non-independent suspension at the rear.
I've been driving for years and have replaced the remote key battery for my BYD F3 several times. The battery model is the standard-sized CR2032 button cell, which costs just a few bucks at the supermarket. I recommend Panasonic or Sony brands for better durability. Replacing it is quite simple: use a coin or small screwdriver to gently pry open the back cover of the key—don’t use too much force to avoid scratches. Remove the old battery and replace it with a new CR2032, making sure the positive side faces up, otherwise it won’t work. After replacement, test the buttons to see if they unlock the car door. Typically, the battery lasts two to three years, but if the remote range shortens or the buttons respond slowly, it’s time for a replacement. Always keep a spare battery in the car for emergencies—don’t wait until the key completely dies to act. Doing it yourself saves time and money, adds a sense of accomplishment, and is really convenient.
