Car key battery models: Car remote keys use button batteries, mainly in the models CR2016, CR2025, and CR2032. The specific model can be determined based on the model used in each car or the battery model specified in the user manual for replacement.
I've been driving the Weltmeister EX5 for almost three years and have replaced the key battery three times, each time with a CR2032 model. This small, round battery is incredibly common and can be easily purchased at supermarkets or online. The first time I replaced it, I was all thumbs and nearly broke the edge of the key. Later, I learned to use a plastic card to gently pry open the latch—just take it slow. The battery lasts about a year and a half, depending on how frequently you use the car. If the buttons feel stiff or the remote range shortens, it's usually just a low battery signal—no need to rush to the repair shop and waste money. By the way, I recommend Sony or Duracell brands for batteries; avoid no-name brands to prevent leakage that could damage the internal circuits. Also, keep the key in your bag without heavy items pressing on it to extend its lifespan.
Weima's remote key uses a CR2032 lithium-manganese battery with a standard 3-volt output. After checking the car manual and community discussions, I found this model is widely available in the market with consistent dimensions. Replacing it is simple: use a small screwdriver or coin to pry open the key's back cover, remove the old battery, insert the new CR2032 with the positive side facing up, and close the cover. If the battery dies, it may cause lag when unlocking, so replace it early to avoid being stranded outside the car. Compared to gasoline cars, electric vehicle keys have simpler circuits and are less prone to other malfunctions. It's recommended to check the battery level once a year—don't slack off. Also, avoid placing the key near strong magnetic fields, such as phone signal blockers.
CR2032 is the standard model. I often help people replace it in the store, and it only takes a few steps: use a thin piece to pry open the key cover, remove the old battery and replace it with a new CR2032, then press it firmly. Common issues like slow response or malfunction of the buttons are almost always due to battery aging; keeping a pack of Panasonic batteries on hand is both economical and convenient. The key design is quite user-friendly, requiring no additional tools, and it can be done in five minutes. Don’t be nervous—just give it a try and you’ll see how easy it is.
