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.

As a tinkerer, I use CR2032 batteries for my BYD F3 remote key. It measures 20mm in diameter and 3.2mm in thickness, belonging to the lithium-manganese battery type, known for its strong power and long endurance. When replacing the battery yourself, be careful not to let your fingers touch the electrodes to prevent static electricity from damaging the circuit. The steps are super simple: use a thin tool like nail clippers to pry open the key shell, remove the old battery, and place a new CR2032 inside. After completion, close the lid and shake it to test the button response. Common issues include the battery being installed backwards causing malfunction or dirty contacts needing cleaning. It's recommended to check it every two years to avoid being stranded during long drives—a pretty hassle-free little maintenance task.

The BYD F3 remote key running out of power is usually due to the CR2032 battery. Replace it promptly, as delaying could leave you unable to lock the doors. Changing the battery is quick: pry open the back cover, remove the old battery, purchase a new CR2032, and insert it in the correct orientation. Be careful with the small battery compartment to avoid damage, and test the key after replacement to ensure it works. Keep a spare battery in the car for emergencies—safety first to avoid hassle.
