3. Battery Replacement (Setup)
Replacing the battery in your key fob is a straightforward process and does not require remote reprogramming. Follow these steps carefully:
- Prepare Your Workspace: Ensure you have a clean, well-lit area. Gather your key fob, the new CR2025 battery, and the included pry tool.
- Locate the Seam: Examine your key fob to find the seam where the two halves of the casing meet. This is typically along the edge of the remote.
- Open the Key Fob: Carefully insert the tip of the provided blue pry tool into the seam of the key fob. Gently twist or pry to separate the two halves of the casing. Apply steady, even pressure to avoid scratching or damaging the remote case. The pry tool is designed to assist in opening the remote without causing damage.

- Remove the Old Battery: Once the key fob is open, locate the existing CR2025 battery. Note its orientation (which side is facing up, usually the positive '+' side). Use the pry tool or a small non-metallic object to gently lift and remove the old battery from its compartment.
- Insert the New Battery: Take one of the new CR2025 batteries. Insert it into the battery compartment, ensuring the positive '+' side is facing the same direction as the old battery was. The battery should fit snugly into place.
- Close the Key Fob: Align the two halves of the key fob casing and gently press them together until they snap securely into place. Ensure there are no gaps and the case is fully closed.
- Test the Remote: After closing the key fob, test its functionality by attempting to lock and unlock your vehicle.
A detailed step-by-step instructional video demonstrating the battery replacement procedure is typically provided via a link on the product packaging. Please refer to that resource for a visual guide.
4. Operation
Once the new CR2025 battery is correctly installed, your key fob will resume normal operation without requiring any reprogramming. The remote's functions, such as locking, unlocking, and trunk release, should work as they did prior to the battery replacement.
5. Maintenance and Storage
Proper handling and storage of batteries can extend their shelf life and ensure safe operation:
- Storage: Store unused CR2025 batteries in their original packaging in a cool, dry place, away from direct sunlight and extreme temperatures.
- Disposal: Dispose of used batteries responsibly according to local regulations. Do not dispose of batteries in household waste. Many retailers and recycling centers offer battery recycling programs.
- Child Safety: CR2025 coin cell batteries can be a choking hazard. Keep them out of reach of children and pets.
6. Troubleshooting
If your key fob does not function correctly after replacing the battery, consider the following troubleshooting steps:
- Battery Orientation: Re-open the key fob and verify that the new CR2025 battery is inserted with the correct polarity (positive '+' side facing up, as noted during removal).
- Secure Connection: Ensure the battery is seated firmly in its compartment and making proper contact with the terminals.
- Case Closure: Confirm that the key fob casing is fully closed and snapped together without any gaps. An improperly closed case can sometimes interfere with button presses or internal connections.
- Battery Condition: Although new, ensure the battery itself is not faulty. If you have another new CR2025 battery, try swapping it to rule out a defective battery.
- Key Fob Damage: Inspect the internal components of the key fob for any visible damage or corrosion that might have occurred during the battery replacement process or prior.
