2 Answers
You can replace the car key battery at a 4S shop or do it yourself. The functions of a car key include: 1. Closing the windows automatically after turning off the engine. 2. Locating the car conveniently in a parking lot. 3. Automatically opening the trunk. 4. Remotely opening the windows. Precautions for using a car key are: 1. Do not place it together with electronic devices. 2. Avoid exposing the key to high temperatures or direct sunlight. 3. Do not use batteries with different power levels. The steps to replace the key battery are: 1. Take out the car key. 2. Insert a flat-head screwdriver into the gap on the side of the key to open the key cover. 3. Remove the old battery and replace it with a new one.
When my car key battery dies, I usually choose to go to a 4S shop or a brand-authorized service center to replace the battery because they use original equipment manufacturer (OEM) parts, which have a high compatibility and are less likely to cause issues. Although the cost might be a bit higher than other places, it saves me the hassle. I also like to keep a spare key handy to avoid last-minute emergencies. If the 4S shop is far away, supermarkets or convenience stores sometimes sell universal batteries, but I always make sure to check the battery model of my key first, such as the common CR2032, to avoid buying one that doesn’t fit. I also recommend regularly checking if the key’s indicator light is dimming—replacing it in advance can prevent being stranded halfway, especially in winter when batteries drain faster. Before driving, it’s safer to shake the key a bit to test the signal. Simply put, choosing a reputable place to replace the battery is the most reliable option; don’t try to save a few bucks at a roadside stall.
