How to Replace the Key Fob Battery in a Chevrolet Malibu Hybrid

Steps from the 2010 Chevrolet Malibu Hybrid owner's manual.

Pry the transmitter apart with a flat, thin object inserted into the notch on the side.
Take out the old battery without using a metal object.
Insert the new battery with the positive side facing up.
Use a CR2032 or equivalent battery.
Snap the transmitter back together.

Replace the battery when the KEY FOB BATT (Battery) LOW message shows in the DIC.
Do not touch the circuitry on the transmitter, as static from your body could damage it.
