Where can I replace the car key battery?

You can purchase and replace the car key battery by yourself, or have it replaced at a repair shop. Car key batteries are usually CR2032, and other models include CR2025, CR2016, and CR1632. Here, 'CR' stands for lithium battery, '20' represents the battery diameter (20mm), and '32' indicates the battery thickness (3.2mm). A car key is a tool for switching the car on and off. Modern car keys all use chips, which are part of a magnetic chip system. The reading coil in the car ignition lock cylinder will read the chip in the key, and each chip contains fixed digital information.
