What are the steps to replace the key battery of the Baojun 510?

The Baojun 510 key requires a CR2032 battery when replacing. There are two types of keys, and the battery replacement process differs slightly for each: 1. Pull-out type (mechanical key): Use the release switch on the key to pull out the mechanical key. To replace the battery, first remove the mechanical key, then use a tool like a flathead screwdriver to pry open the key shell along the side gap. Once opened, the key splits into two parts: one side contains the key circuit board, and the other side holds the battery. Remove the old battery and install the new one, paying attention to the correct polarity. Then reassemble the key shell and mechanical key. 2. Folding type: First, unfold the mechanical key. Then, use a flathead screwdriver to open the upper cover at the key logo position. Next, use a Phillips screwdriver to remove the fixing screws under the upper cover and take it off. Remove the lower cover, replace the old battery with a new one, and then reassemble the covers.
As someone who often helps friends with car repairs, I just assisted my neighbor in replacing the battery of their Baojun 510 key fob last week. The first step is to remove the mechanical key—there's a small button on the side; press it and pull it out. Next, use a thin plastic card or your fingernail to gently pry open the key fob shell by inserting it into the seam in the middle. Be careful not to use excessive force, or the plastic shell may crack. Inside, you'll find a flat, round battery. Remember, the model is CR2032, and the positive side of the battery must face upward, aligning with the '+' symbol marked on the key fob. These batteries are available at supermarkets or hardware stores for about ten yuan. After installing the new battery, press the cover firmly until you hear a click, indicating it's securely fastened. The whole process takes about five minutes—just make sure not to insert the battery backward, as the buttons won't work if it's reversed.
I drive a Baojun 510 myself. Last winter, when I noticed the remote control distance became shorter, I knew it was time to change the battery. First, pull out the mechanical key. There's a square hole at the tail of the key which is the breakthrough point. Use a flathead screwdriver or a coin, insert it along the edge and give it a gentle twist, and the back cover will pop open. The old battery is usually stuck quite tightly, just pry it out from the side with a small blade. Remember the battery model is CR2032, buying it online for five yuan is much cheaper than at the 4S shop. When putting in the new battery, pay attention to the positive and negative poles—the side with the engraving must face outward. When closing the cover, first align the two clips at the bottom, then press the top. After replacing, it's best to test the response distance of the lock button; as long as it responds within twenty meters, it's fine. The most worrying part of the whole process is scratching the shell with metal tools, so plastic pry bars are the safest.
