How to Replace the Battery in a Highlander Remote Key?
2 Answers
To replace the battery in a Highlander remote key, follow these steps: 1. On the back of the remote, there is a circle with a groove in the middle. Use a coin to turn the groove counterclockwise until it aligns with the small triangle mark on the edge of the circle to open the cover; 2. Remove the old battery and replace it with a new one according to the number on the button battery. Taking the 2020 Highlander as an example, its body dimensions are: length 4890mm, width 1925mm, height 1715mm, wheelbase 2790mm, and fuel tank capacity 72.5l. The 2020 Highlander features a MacPherson strut front suspension and an E-type multi-link rear suspension. It is equipped with a 2.0L inline 4-cylinder turbocharged engine, producing a maximum horsepower of 220ps, maximum power of 165kw, and maximum torque of 350nm, paired with a 6-speed automatic transmission.
I'm quite familiar with changing the battery in the Highlander's remote key - it's no problem to do it myself. First, press the small switch on the side of the key while gently pulling out the mechanical key. Then carefully pry open the key casing using a flathead screwdriver or plastic pry tool along the edge seam - avoid using excessive force to prevent scratches. Inside you'll find the battery; the Highlander typically uses a CR2032 coin cell. Make sure to note the positive and negative orientation when replacing it. When reassembling, first snap the top and bottom shells together securely before reinserting the mechanical key. I recommend testing the remote function immediately after battery replacement - walk to your car and press the unlock button to check responsiveness. By the way, remember to clean any accumulated dust inside the key before replacing the battery, as built-up dust can affect circuit board contact. Doing it yourself costs only about 5 yuan, much cheaper than going to the 4S shop.
