I just replaced the battery in my Haval H2 key fob, and it was quite easy. There's a small screw hole on the back cover of the key—just gently unscrew it with a Phillips-head screwdriver, avoiding excessive force to prevent stripping. Then carefully pry open the casing to reveal the battery, most likely a CR2032. Remember to note the orientation with the positive side facing up. To remove the old battery, simply use your fingers to gently pop it out. Before installing the new battery, buy an original or compatible one from the supermarket—don’t cheap out on low-quality replacements. Ensure the positive and negative sides are aligned correctly. Close the casing and tighten the screw, then test the remote buttons for lock and unlock functions to confirm normal operation. To prolong battery life, avoid dropping the key on the floor. I recommend replacing the battery every two years to prevent sudden failure during trips—it’s both convenient and safe. Keeping a spare key is also very helpful.

Replacing the battery for my Haval H2 key was something I learned online. I was a bit nervous the first time but succeeded. The key is usually held together by clips, so just press the edges firmly and pry it open—don’t force it to avoid breaking. Inside, the battery is round, likely a CR2032, which I bought from a convenience store for about ten yuan per pack. When removing the old battery, avoid touching it with wet hands and gently push it out. For the new battery, confirm the orientation—the shiny side faces outward—and align it properly before placing it in securely. Then, snap the case back together until you hear a click. Test the remote function immediately afterward by locking the car and checking if the lights flash. The battery lasts about a year, draining faster in winter, so it’s good to keep one or two spares at home to avoid last-minute store runs. The whole process is simple, taking around five minutes with just your fingers and maybe a small knife for assistance—no need to worry about difficulty.
