Understanding Lexus Car Key Batteries
Lexus car keys, like many modern car keys, use a type of battery called a CR2032 or CR2032 lithium battery. These batteries are small, coin-shaped, and provide a reliable source of power for the key’s electronic components.
The CR2032 battery is a common type of battery used in many electronic devices, including car keys, watches, and calculators. It’s a small battery, measuring only 20mm in diameter and 3.2mm in thickness. Despite its small size, the CR2032 battery packs a punch, providing a reliable source of power for the key’s electronic components.
The CR2032 battery is also known for its long lifespan, typically lasting up to 10 years or more, depending on usage. However, like all batteries, it will eventually run out of power and need to be replaced.
