Which car key battery I should use?

Look for a label or marking on the battery. The battery type is typically printed on the battery itself or on the packaging. This information may be written in small print and can be difficult to see, so you may need to use a magnifying glass or a flashlight to get a better look. Some common battery types include CR2032, CR2025, CR2016, and CR2035.

Check the size and shape of the battery: In some cases, you may not be able to find a label or marking on the battery. In this case, you can try to identify the battery type based on its size and shape. Car key batteries are usually small and flat, and they may have a circular or rectangular shape. You can use a battery size chart or a battery cross reference chart to compare the size and shape of your battery to a list of common battery types.

Consult the owner's manual: If you are still unable to determine the battery type, you can try consulting the owner's manual for your car. The owner's manual should contain information about the battery type and other technical specifications for your car. You can usually find the owner's manual in the glove compartment of your car or online at the manufacturer's website.
