Pry open the key casing along the seam. Remove the old battery and install the new one.
Changing the battery in a Haval car key is actually not difficult. I managed to do it myself last time. First, locate the seam on the side of the key and gently pry it open using a coin or a thin card. Avoid using hard tools like screwdrivers as they can scratch the casing. Once opened, you'll see the coin cell battery sitting in its slot—the common model is CR2032. Before removing the old battery with a toothpick, it's best to take a photo to note its orientation, then insert the new battery the same way. Align the cover and press it back into place—the whole process takes less than 5 minutes. Remember to buy the correct battery type in advance; they're usually available at supermarket electronics counters. If the key has a mechanical lock cylinder, remove it first and set it aside to avoid losing it.
I usually enjoy tinkering with these small things, and replacing the battery in a Haval car key is a piece of cake. Before disassembling, it's best to prepare a plastic pry tool and gently lift at the seam of the key casing. There's often an arrow mark on the back of the key, which is the easiest spot to pry open. After opening, don't rush to remove the battery—first, check the structure of the battery compartment's clips. Some models require pressing a small spring tab to release the battery. When installing the CR2032 battery, make sure the positive side faces up (the side with the printed text). When closing the casing, listen for a click to ensure it's properly secured. After replacing the battery, it's a good idea to test the signal by pressing the lock button a few times at home before venturing far. If the car is over three years old, take this opportunity to also check if the key casing's sealing ring has aged.
Replacing the battery in your Haval car key yourself costs just a few bucks, much cheaper than going to the dealership. You can wedge your fingernail into the seam along the key edge and gently pry open the casing. Note there might be an anti-slip rubber pad in the battery compartment - lift it to reveal the battery. The battery model (usually a 3V CR2032 coin cell) is printed on the old battery. Avoid touching the electrodes directly during installation as oil residue can impair conductivity. After reassembling, press firmly on all four corners to ensure proper sealing. Wipe down the casing, especially around the button crevices where dust accumulates. Perform the entire operation in bright lighting to prevent losing small components.
