The BYD F3 key has two types of batteries: 1. The remote key battery model is 1632; 2. The card key battery model is 2025. Steps to replace the BYD F3 key battery: 1. Pull out the mechanical key and pry open along the shallow groove at the top of the key; 2. Remove the old battery and install the new one; 3. Reassemble the key. The BYD F3 is a sedan produced by BYD Auto, positioned as a mid-level family car. In terms of body dimensions, the car measures 4.533 meters in length, 1.705 meters in width, and 1.490 meters in height, with a wheelbase of 2.6 meters.
I've been using my BYD F3 for several years and have encountered the key fob battery dying a few times. It uses the CR2032 coin cell battery, which is very easy to replace yourself. Just search for CR2032 on online marketplaces like Taobao or JD.com, and you can get several for just a few bucks. When opening the key fob case, be careful - use a flathead screwdriver to gently pry open the clips, but don't use too much force to avoid cracking it. When inserting the new battery, align it with the polarity markings (usually letters facing up). Test the remote functions immediately after replacement. I recommend keeping one or two spare batteries in your car since these typically last 1-2 years depending on usage frequency. I find DIY replacement saves time and avoids unnecessary trips to the dealership. After learning how, I've even helped friends replace batteries for other car models - the method is similar though battery sizes may vary.
I'm the type who enjoys tinkering with car accessories. The BYD F3 key fob typically uses a standard CR2032 battery. It operates at 3 volts, has a compact size, and offers stable performance, making it ideal for remote signal transmission. When purchasing, opt for reputable brands like Panasonic or Energizer for longer-lasting performance—these are readily available at supermarkets or auto parts stores. When the battery is running low, you'll notice reduced remote range or slower button response, which signals it's time for a replacement. I've personally tested with a multimeter—once the voltage drops below 2.5 volts, the battery becomes ineffective. During replacement, avoid letting metal tools touch the circuit board to prevent short-circuiting and damaging the internal chip. Cleaning the battery compartment contacts of dust can also help the new battery last longer. For preventive maintenance, an annual check can prevent sudden malfunctions.
Last time my BYD F3 key fob stopped working, and after checking I found it was a CR2032 battery issue. The 4S store charged dozens of yuan for replacement, which was too expensive and not worth it. I searched online and found the battery model was CR2032, then bought 5 of them on Pinduoduo for just a few cents each. After putting it in, it worked perfectly. Saved myself the hassle and expense of going to the shop. I recommend learning to do it yourself – just check YouTube tutorials for steps to open the key fob shell, it's super simple. Buying batteries in bulk and keeping spares at home saves both money and hassle. If worried about wrong size, just confirm the CR2032 marking on the battery box. These small round batteries might also be available at local pharmacies. After fixing the remote, note down the battery model immediately so you can replace it proactively next time to avoid travel disruptions while driving.
