What Type of Battery Does a Car Key Use?
1 Answers
The battery used in car keys is a button cell battery. The most commonly used car key batteries are of the following three types: 1. Button-type CR2016 battery. 2. Button-type CR2025 battery. 3. Alkaline 12V battery. Below is an introduction to the relevant content: Generally, car key batteries operate on 9V power, so each battery replacement requires replacing all three batteries. This applies to remote keys for models such as Honda, Toyota, Volkswagen, Mazda, etc. The usage rate of the button-type CR2025 battery is lower than that of the CR2016. It is relatively thicker than the 2016 but has a higher storage capacity. The specifications of the CR2025 type are: battery diameter of 20mm and thickness of 2.5mm. Alkaline 12V batteries are mostly used in early car key remotes and electric rolling shutters or doors in shops. Their characteristics include small size, high output voltage, and a longer remote control distance for the remote.
