Once you have a battery and cleaned your fob, you can move on to opening the case. You do not want dirt or grime falling into the switches inside the fob when you open it up. While you have the key out of use, and before taking it apart, clean off the fob and the key with a damp cloth or wet wipe. It is worth buying a small pack of cells since you will have a few remotes around your home using the same battery. Electronics, jewelry, grocery, and hardware stores, and toy shops should all sell these batteries. The CR-2032 is inexpensive, and you can buy them as single cells or as a pack. These are a common battery that fit into small remotes and children’s toys. Most Toyota key fobs will use CR-2032 3-volt batteries, some use CR-2016’s, but you can check in your car’s user manual.
