There will be a small slot, indentation, or button that allows the battery compartment to be opened.
If the markings are worn away, refer to the owner’s manual diagram for help identifying the compartment.

Step 3: Open Battery Compartment of Key Fob

To open the battery compartment, insert a small flathead screwdriver or similarly shaped tool into the slot/indentation.
Alternatively, use a coin like a dime or nickel to pry open the compartment if no screwdriver is available.
Gently turn or wedge the tool in the slot to pop open the battery compartment. Take care not to damage the plastic housing.

Step 4: Remove Old Battery from Key Fob

Once the compartment is opened, the CR2032 battery should be visible, often with a plastic tag adhered to pull it out.
If no tab is present, shake the key fob gently to dislodge the battery or use tweezers to extract it carefully.

Ensure the positive and negative terminals align correctly based on the inner compartment markings.
If inserted backwards, the key fob will not function.

Step 6: Close Battery Compartment

For a slot compartment, slide the plastic cover back into place until it snaps shut.
For a button compartment, realign the cover and press gently until it clicks and secures the battery inside.

Step 7: Test Key Fob Operation

Press the lock, unlock, remote start, or panic buttons on the key fob to verify normal operation.
