Volvo S90 key battery replacement method is: 1. Use a coin to press into the circular groove on the back and twist open the cover to reveal the button battery; 2. Use an appropriate tool matching the groove size to unscrew the seam between the front and back covers; 3. Purchase a new battery with the same model number as the original for replacement. The Volvo S90 is a mid-to-large-sized 4-door 5-seater sedan with body dimensions of: length 5090mm, width 1879mm, height 1450mm, and a wheelbase of 3061mm. It is equipped with a 2.0T turbocharged engine and an 8-speed automatic transmission, delivering a maximum power of 184 kW and a maximum torque of 350 Nm. The drivetrain configuration is front-engine, front-wheel drive, with front suspension using double-wishbone independent suspension and rear suspension employing multi-link independent suspension.
Actually, changing the key battery for a Volvo S90 is quite simple and can be done at home. First, look for a small button on the side of the key—press it to pull out the mechanical key. Then, use the flat end of this mechanical key to gently pry open the back cover by inserting it into the gap of the key casing. Last time I changed it, I found a CR2032 coin battery inside, with the positive side facing up when inserting. Before placing the new battery, remember to wipe the battery slot with a tissue to prevent poor contact. Finally, align the casing and press firmly until you hear a click, indicating it's properly installed. Avoid using excessive force throughout the process, as the plastic clips can break easily. I usually change it every two years, and buying the battery at the supermarket costs only about ten yuan.
Replacing a Volvo key battery is actually a four-step process. First, press the small indented button on the top of the key and pull out the metal mechanical key. Second, insert the mechanical key into the seam of the plastic casing and gently twist to pry open the shell—starting from the charging port side is easiest. Third, you'll see the silver coin battery, model CR2032. Use your fingernail to pry out the old battery from the edge, and when installing the new one, make sure it's not upside down—the side with the plus sign should face upward. Fourth, align the cover and press it firmly into place, then reinsert the mechanical key. The whole process takes about three minutes. I recommend choosing Panasonic or Sony batteries for better durability.
