Most car keys require a CR2032 or CR2025 3-Volt battery. Battery types may differ by car model. Check your owner’s manual for the correct battery specifications for your key fob. This step ensures you choose the right battery to maintain optimal functionality.
To replace the battery, begin by gently prying the key fob apart. This usually requires a small screwdriver or a flat tool. Once opened, remove the old battery. Note the orientation of the battery; it must be installed in the same way for the new one to work correctly. Insert the new battery, ensuring it fits snugly.
