First, press the button on the BYD car key. Then, pull out the mechanical key. After that, use a screwdriver to insert it along the gap of the key shell. Next, use a toothpick to remove the old battery. Install the new battery into the battery compartment. Finally, put the key cover back on, and the battery replacement is complete.

I've been driving a BYD for several years and have plenty of experience changing remote control batteries. Usually, when the battery is low, the button response slows down or the remote control distance shortens, which means it's time for a replacement. Prepare a small plastic pry tool or a hard plastic card—avoid using metal to prevent short circuits. Locate the small seam on the edge of the remote and gently pry open the back cover. After opening, remove the old battery, which is a CR2032 model—you can easily find a new one at supermarkets or auto parts stores. When inserting the new battery, make sure the positive side faces upward, with the printed side aligned with the contacts. Close the cover and press it firmly, then test the lock and unlock buttons. If the indicator light turns on, you've succeeded. The whole process takes less than ten minutes and saves you repair costs. I recommend changing it every two years or immediately when the battery weakens to avoid affecting driving safety. Keeping a few CR2032 batteries at home is also quite convenient.

I enjoy tinkering with minor car repairs myself, and changing the battery in a BYD remote is not difficult at all. The side clips on the remote are well-designed, and you can easily pry open the cover using a plastic card, like an old bank card. Just be careful not to use too much force to avoid damaging the casing. Once opened, remove the old CR2032 battery and replace it with a new one—make sure the model matches to avoid buying the wrong type. Insert the new battery with the positive side facing up, then close the cover and immediately test if the buttons light up properly. If there’s any issue, check if the battery is inserted backward or if there’s poor contact. Keep an eye on battery life; it typically lasts one to two years. Doing it yourself not only saves money but also helps you understand vehicle maintenance details, improving daily convenience. With a bit of practice, you’ll get faster, and any plastic tool will do the job.

If the BYD remote control buttons are unresponsive, it may be due to a depleted battery. Simple solution: Use a plastic card or thick credit card to gently pry open the back cover of the remote, then remove the old CR2032 battery. Purchase a new CR2032 battery and insert it with the positive side facing up. Close the cover and test the buttons to ensure they work. This can be done in five minutes, saving a lot of hassle. Remember to operate in a dry place to prevent short circuits. Regularly checking the signal strength can help detect issues early.
