How to Replace the Key Fob Battery in a Chevrolet Silverado

Steps from the 2020 Chevrolet Silverado owner's manual (RKE transmitter with a removable key).

Press the button on the RKE transmitter and remove the key.
Insert a flat, thin object in the center of the transmitter to separate and remove the back cover.
Lift out the old battery with a flat object.
Insert the new CR2032 or equivalent battery with the positive side toward the back cover.
Push the transmitter back together.
Insert the key back into the RKE transmitter.

Replace the battery soon when the DIC displays REPLACE BATTERY IN REMOTE KEY.
Do not touch the circuitry inside the transmitter; static could damage it.
Never pull the key out without pressing the button.
