What is the battery model for a car remote key?

[Miguel]

Car remote keys typically use button cell batteries, mainly in the models CR2016, CR2025, and CR2032. Button-type CR2016 battery: This is one of the most commonly used batteries for car remote keys today. These batteries have a voltage of 3V. Since most car key remotes operate on 9V power, all three batteries are usually replaced at the same time. Button-type CR2025 battery: This model is far less commonly used than the CR2016. However, some car keys still utilize it. It is thicker than the CR2016 but has a relatively higher storage capacity. Button-type CR2032 battery: This battery also has a voltage of 3V, but its capacity reaches around 200mAh, making it twice as thick as the CR2016.
