Roewe car key needs battery replacement under the following circumstances: 1. The remote control distance becomes shorter. When the remote control has sufficient power, the remote control distance can reach more than 20 meters; when the car key battery is low, the remote control distance will become shorter. 2. The indicator light does not light up or becomes dim during remote control. To prevent the owner from pressing the wrong button or accidentally pressing a certain button, the button indicator light usually lights up when the car key is pressed. If you suddenly find that the indicator light does not light up or the indicator light is not as bright as before, it means that the car key battery is low. The method for replacing the car key battery is as follows: 1. Locate the button on the top of the Roewe car key, press the button and pull out the mechanical key. 2. Use a flat screwdriver to pry open the buckle on the side of the key and remove the cover of the car key. 3. After opening the cover, you can see the battery inside, remove the old battery and replace it with a new one. 4. Put the car key cover back on to complete the car key battery replacement.

I just replaced the battery in my old Roewe car key, which is actually quite simple. First, locate the small seam on the side of the key, then gently pry open the casing using a flathead screwdriver—be careful not to apply too much force and break the plastic clips. Once opened, you'll see the coin battery; Roewe commonly uses the CR2032 model, which costs just a few yuan at a hardware store. When installing the new battery, pay attention to the orientation—the side with the text should face upward. The whole process takes about five minutes, but it's best to work on a soft cloth to avoid scratching the key. After replacement, remember to test the locking function; if it doesn't work, the battery might not be properly seated. If the key ever gets wet, disassemble it immediately to dry it off, as battery leakage can corrode the circuit board.

Last month, I just helped my neighbor change the battery in her Roewe key fob. The decreasing remote range was a clear sign of battery aging. First, find a well-lit area to work in. The back of the key usually has screws or clips, and Roewe key fobs often have clips on the side. After opening the casing, don't rush to remove the battery—first, take a photo with your phone to remember the orientation. There might be small springs in the battery slot; gently pry them open with a toothpick to remove the old battery. Here's the key point: when inserting the new battery, you should hear a 'click' to ensure it's securely in place. When reassembling the casing, snap the bottom first, then press the top until you hear a slight 'click,' indicating the clips are properly engaged. The waterproof seal on my neighbor's key was worn out, so I applied a bit of Vaseline to enhance the seal.

Changing the battery in a Roewe car key is actually quite simple—just remember three steps: find the right tools, identify the correct battery model, and pay attention to the orientation. You can pry open the key casing with a coin, and the battery model is usually CR2032. When removing the old battery, avoid direct metal contact with the positive and negative terminals to prevent short circuits. When installing the new battery, ensure the positive side faces upward and align the casing properly with the slots. Last time I changed mine, the trunk button didn’t work, and upon reopening, I found the battery wasn’t pressed in firmly. It’s recommended to replace the battery every two years to avoid sudden failure. Some older Roewe keys might use the 1632 model, so it’s best to check the manual beforehand.
