Replacing the battery in a Beijing Hyundai key is a job I've done a few times, and it's pretty simple. Usually, the key is either a folding type or a smart key—first, check which type you have. For the folding key, there's a small button on the side; press it to pop out the mechanical part. The battery is on the back, and you can gently pry open the casing with a small screwdriver or your fingernail. For the smart key, there’s a seam on the casing—use a thin tool to slowly pry it open. After removing the old battery, note the positive and negative orientation (CR2032 button batteries are the most common). When inserting the new battery, align the positive side with the contact point and press it in gently. Before closing the casing, make sure the clips are aligned and press firmly. Test the lock button—if the light turns on, you’ve succeeded. The battery usually lasts two to three years before needing replacement; weakened signal strength is a sign it’s time. I recommend buying genuine batteries—don’t skimp to avoid leakage damaging the circuit. If your hands are shaky, wear gloves for grip and keep dirt from getting inside.
I drive a Beijing Hyundai, and replacing the key battery feels like solving a puzzle. First, prepare a CR2032 battery, which you can buy at a pharmacy or online. The key fob usually has a small notch—be gentle when prying it open to avoid breaking it. After opening, remove the old battery, and when inserting the new one, make sure it’s not upside down; the positive side usually faces up. Then snap it shut—you should hear a click. Test the remote range to ensure it works within 20 meters. When the battery is low, the car will beep as a warning, so replace it promptly. By the way, avoid leaving the key in hot places, like inside a car under the sun, as it drains the battery faster. The whole process takes about five minutes, saving you time and money compared to visiting a dealership. Before starting, dry your hands to prevent static electricity.
I've repaired quite a few car keys, most Hyundai models in Beijing use CR2032 batteries. First step, locate the seam on the key, usually you can gently pry open the shell using a plastic card or small knife. Be careful not to cut your hands. Remove the old battery, paying attention to the marked orientation. Install the new battery with the positive side facing the contacts, press firmly. After closing the shell, press the button to test if the light comes on. Weak key signal is usually caused by battery aging, recommended to check every two years. DIY replacement is low cost, just a few yuan for a battery. If it's hard to pry open, the lock type might be different - consult the manual or ask after-sales service. Just make sure your tools are clean.
