There are 3 steps to replace the car key battery: 1. Flip the switch to remove the mechanical key; 2. Insert the mechanical key into the slot where it is stored and twist it; 3. Remove and replace the battery, then snap the panel back into place. Below are some details about the Highlander: 1. Powertrain configuration, equipped with a 3.5L V6 engine: paired with a stepped 5-speed automatic transmission with manual mode, providing smooth acceleration and good fuel economy; 2. Exterior design, featuring a stylish and elegant appearance: triangular headlights, a hexagonal angular front grille, an integrated Toyota emblem, and thick chrome accents; 3. Interior space, with a well-arranged center console for easy operation: the Highlander's interior design is simple and elegant, with numerous buttons on the center console that are logically placed for convenient operation; the craftsmanship is refined, with even seams; the interior color scheme exudes nobility and elegance.
I remember last time changing the battery for my Highlander key fob was quite simple. First, make sure to buy the correct CR2032 coin cell battery, which is available at supermarkets or hardware stores. I used a small screwdriver to gently pry open the key fob along the middle seam, but be careful not to apply too much force to avoid scratching the casing. Once opened, you'll see the small silver coin-like battery—just use a thin tool to pop it out. When installing the new battery, pay attention to the polarity; usually, the side with the '+' sign faces upward. Close the cover and press firmly until you hear a 'click' sound. After replacement, test the window controls and locking functions by pressing the buttons a few times. It's recommended to replace the battery every two or three years to avoid sudden power failure inconveniences. Last time at our car club event, we even taught everyone to replace the spare key fob battery as well.
As a long-time Highlander owner, I've replaced the battery three times. The new Highlander key is slightly thinner than the old version, but the structure is similar. DIY replacement costs less than 10 yuan, while dealerships charge over 50. The key is to use OEM-spec batteries - off-brand ones tend to leak and cause corrosion. Some owners tried rechargeable batteries with poor results, so I don't recommend them. Steps: Place the key flat on a table, insert fingernail into the back cover gap and pry it open. When removing the old battery, note the electrode slot position. Avoid fingerprints on the new battery as they affect conductivity. Finally, align and press the front and back covers together - good opportunity to clean dust inside. Once my key malfunctioned after being dropped, and I fixed it by disassembling and adjusting the battery holder myself.
