Highlander car key battery model is CR1620. Car key battery models: Car remote keys use button batteries, mainly CR2016, CR2025, and CR2032. For specific models used in each vehicle, owners can refer to the battery model in the user manual for replacement. Highlander key battery replacement method: On one side of the car key, locate the notch; use a screwdriver to pry open the key; after opening, you will see the round button-shaped battery, remove it; install the new battery you prepared; then snap the key shell back together, and the battery is successfully replaced.
I've been driving my Highlander for several years, and the key fob battery is a CR2032 coin cell, which typically needs replacement every two to three years as it depletes over time, causing slower response when remotely unlocking the car. The replacement process is simple—just pry open the key casing with a thin tool. These batteries are readily available at supermarkets or auto parts stores for under 10 yuan each, but avoid off-brand ones as they may shorten lifespan. I've replaced mine twice, always with the original-compatible CR2032 model (3V voltage, perfect for powering electronic signals). Keep the key dry and avoid water exposure; when changing batteries, ensure correct polarity alignment to avoid unnecessary trips to the dealership for costly fixes.
I have more knowledge about car key batteries. The Highlander smart key commonly uses the CR2032 model, which is a lithium coin cell battery with a 3-volt output that meets the requirements of the remote control system. The battery has a diameter of 20mm and a thickness of 3.2mm, making it widely available and easy to replace. Toyota standardized this model during design, and other Japanese cars are similar, ensuring stable power supply. Remember to check if the key contacts are clean when replacing the battery. If the battery is installed backward or mismatched, it may damage the circuit and affect the sensing function. Normally, when the key signal weakens, it's time to replace the battery, typically lasting about two years with regular use. Regular maintenance is recommended to avoid emergencies.
