Follow these easy steps to replace the battery in your 2019 Toyota Corolla key fob:

Locate the small release button or notch on the side of your key fob.
Insert your flat-head screwdriver (or plastic opening tool) into the notch and gently pry open the key fob casing. Be careful not to apply too much force, which could damage the plastic.
Once the casing is separated, carefully identify the old CR2032 battery. It’s usually located in a small compartment.
