Haval H2 remote key battery replacement steps are: 1. Remove the mechanical key and pry open the back cover with a tool; 2. Pry out the old battery for replacement. The Haval H2 body dimensions are: length 4365mm, width 1814mm, height 1710mm, wheelbase 2560mm, and fuel tank capacity 50L. The Haval H2 is equipped with a 1.5T turbocharged engine, with a maximum power of 110kW, maximum power speed of 5600 to 6000 rpm, maximum torque of 210Nm, maximum torque speed of 1800 to 4400 rpm, matched with a 6-speed manual transmission.
Last time I changed the H2 key battery, it was super easy. First, locate the small groove on the side of the key, insert a coin and twist to split it in half. Once opened, you'll see the button battery clipped in place - just gently pry it out with a toothpick. The battery model is CR2032, readily available at supermarkets. When installing the new battery, make sure to align the positive and negative sides correctly, with the shiny surface facing upwards before pressing it in. When reassembling, ensure the clips align properly before pressing firmly. Test all buttons after installation - the lock/unlock functions should show red lights. The whole process takes about 5 minutes, saving over 200 yuan compared to visiting the dealership. Remember to choose Sony or Panasonic batteries with the 3V marking for better durability.
My Haval H2's battery lasted three years before needing replacement. There are two types: mechanical key and smart key. Mine is the smart version with buttons. On the back of the key, there's a hidden clasp - just run your fingernail along the seam to open it. The battery inside looks like a small coin; be careful not to dislodge the adjacent metal spring when removing it. Testing the range with the new battery is crucial - it should successfully unlock from the rear of the vehicle. For the mechanical key version, you'll need to first remove the metal key and unscrew the side screws (a precision screwdriver set is recommended). Don't discard old batteries carelessly - wrap them securely with transparent tape before disposal.
