How to Replace the Key Battery on a Toyota Corolla

Model: Toyota Corolla MK 5, E210 - Years 2019-2026
Part: Key

Often, various malfunctions of the car key are simply due to a flat battery. Unlike many other car key models, for the Toyota Corolla, it is not necessary to disassemble the cover to access the button cell battery. Instead, use a flathead screwdriver to remove a small cover located at the bottom of the smart key. Once removed, you have direct access to the used battery, and you can replace it with a new compatible model. Finally, reattach the cover you removed earlier, and the replacement operation is complete.
