I've been driving the Excelle for several years and always replace the key battery myself when it runs out. First, find a small tool like a screwdriver or even a coin, then gently pry open the edge of the key shell, being careful not to use too much force to avoid damage. There are a few small clips near the keyring area. Once opened, you'll see the battery compartment, which usually holds a CR2032 coin cell. Carefully remove the old battery, taking care not to damage the internal chip. New batteries can be bought at supermarkets or hardware stores. When installing the new one, make sure the polarity is correct with the positive side facing up. Finally, close the shell and press the test button to confirm that the remote lock and unlock functions work properly. I've also noticed that if the key isn't used for a long time, the battery drains faster, so I recommend checking it regularly to avoid discovering the issue just before heading out. The whole process takes at most five minutes, saving you the cost of a trip to the 4S shop.

I enjoy hands-on tasks, and replacing the key battery isn't difficult. The tools needed are simple: use a flat tool to pry open the key's back cover. The design of the Excelle's shell is quite smooth, so it opens easily with a gentle pry. The battery is a common CR2032—just remove the old one and insert the new one. The whole process takes less than two minutes, but don’t forget to check if the battery contacts are clean, as dust can sometimes affect connectivity. Doing it yourself saves money and gives you some practice, with the battery costing just a few yuan. If the battery dies unexpectedly on the road, you can still use the physical key to unlock and start the car. After a few tries, you’ll get the hang of it—there’s no real technical skill required, just a bit of interest.

Changing the car key battery is super easy. I've done it several times with my Excelle key—just pry open the back cover gently, remove the old battery, and replace it with a new one. Remember to buy a CR2032; they're available on supermarket shelves. After installation, test the lock and unlock buttons to see if they light up or function properly. Never had any issues, even beginners can handle it effortlessly—don't overthink it.
