9 Easy Steps on How to Replace Acura Key Fob Case
Step 1. Open the Original Case:
Use the small screwdriver to remove the screws securing the original key fob case carefully. If your key fob does not have screws, you may need to use a flathead screwdriver to pry open the case along the seam gently.

Be cautious when doing this to avoid damaging the internal components. Work slowly and patiently, applying enough pressure to open the case without cracking or breaking it safely. Once the case is open, set aside the screws (if any) and the top piece of the old case in a safe place where they will not get lost.
Step 2. Remove the Battery:
After opening the key fob case, locate the battery, which is usually housed in the center of the unit. Use a flathead screwdriver or your fingers to lift and remove the battery carefully. Be gentle to avoid scratching or damaging the battery compartment, as this will be reused in the new case.
Take note of the battery’s orientation—observe the positive (+) and negative (-) sides—so you can insert it correctly into the replacement case. If the battery appears worn out or corroded, this is a good time to replace it with a new one of the same type, ensuring optimal functionality for your key fob once the replacement process is complete. Set the battery aside in a safe spot to prevent it from rolling away or getting misplaced.
Step 3. Transfer the Internal Components:
With the battery removed, carefully remove the key fob’s internal components, such as the circuit board and any other small pieces, from the old case. Use caution and precision to avoid damaging these sensitive parts. Inspect the components for dirt or dust, and gently clean them with a soft cloth if necessary.
Once removed, place the components into their corresponding slots in the new case, ensuring they are correctly aligned and securely seated. Double-check that none of the parts are loose, as this can affect the functionality of the key fob.
Step 4. Assemble the Key Fob:
Once all the internal components are securely in place within the new case, carefully attach the two halves of the key fob together. Align them properly and press them firmly until you hear or feel them snap into place.
Ensure there are no gaps between the pieces and the case is tightly sealed. If your key fob uses screws, reinsert them and tighten them with the appropriate screwdriver. This step ensures the key fob is assembled correctly and ready for use.

Step 5. Test the Key Fob:
After assembling the key fob, the final step is to test its functionality. Stand close to your vehicle and press the buttons to confirm they work as intended. Check all features, such as locking, unlocking, and any additional functionalities like remote start.
If the key fob does not respond, double-check the battery placement and ensure all components were reassembled correctly. If issues persist, consider consulting your vehicle’s manual or seeking professional assistance. Testing the key fob is essential to ensure it functions effectively and reliably.
Step 6. Maintain Your Key Fob:
Regular maintenance of your key fob can prolong its lifespan and ensure consistent performance. Keep the key fob clean by wiping it with a soft, dry cloth to remove dirt and debris. Avoid exposing it to extreme temperatures or moisture, as these conditions can damage its internal circuitry.
Additionally, replace the battery promptly when it shows signs of fading, such as reduced range or delayed response. Proper care and maintenance of your key fob will help you avoid unexpected issues and ensure it remains a reliable tool for your vehicle.
Step 7. Program Your Key Fob:
If you have replaced the key fob battery or purchased a new key fob, it may need to be reprogrammed to work with your vehicle. Refer to the vehicle’s manual for specific instructions, as the process can vary by make and model. Typically, programming involves turning the ignition key, pressing particular buttons on the dashboard, or using the key fob itself.
Ensure you follow the steps carefully to avoid errors. If you experience difficulties, consult a professional locksmith or your vehicle’s dealership for assistance. Proper programming is critical for the key fob to interact seamlessly with your car’s security system.
Step 8. Keep a Spare Key Fob:

Having a spare key fob can save you from the inconvenience of being locked out or losing your only key. After successfully replacing your key fob case, consider purchasing another one for backup. You can program it yourself or have a professional do it for you.
Keep the spare key fob in a safe and easily accessible place so you can quickly retrieve it in case of an emergency.
Step 9. Personalize Your Key Fob:
Once your key fob is successfully replaced and programmed, take the time to personalize it to suit your preferences. Personalization can be practical or aesthetic, depending on your needs.
For example, you can use a key fob cover or case in your favorite color, style, or material for added protection and to differentiate your key fob from others. Some covers also offer enhanced grip or waterproof features, increasing durability. If you often misplace your keys, consider adding a Bluetooth tracker or keyring attachment that matches your taste.
Lastly, you can program specific functions, such as custom unlock settings or proximity key features, if your vehicle supports them. Personalizing your key fob makes it unique and enhances its convenience and usability.
By following these steps, you can easily replace your key fob case and maintain its functionality for years to come.
