Carrying a key fob that securely unlocks your Subaru is a must. However, a dead battery can be quite frustrating. Don’t fret if you find yourself in such a situation. Changing the battery in a Subaru key fob is a simple task that can be accomplished with a few basic tools and a little know-how.
To begin, you’ll need the right type of replacement battery. The battery type may vary depending on the year and model of your Subaru. Consult your owner’s manual or check online to determine the correct type. Once you have a new battery, locate the small screw on the back of the key fob and carefully remove it using a small screwdriver. Gently pry open the key fob, taking care not to damage the internal components.
Once the key fob is open, you should see the old battery. Use a pair of tweezers or a small flat-head screwdriver to carefully remove it. Be mindful of the orientation of the old battery, as the new battery must be inserted with the positive (+) side facing up. Gently insert the new battery and press down until it securely clicks into place. Now, close the key fob and replace the screw. Test your key fob to ensure that it is working properly and you’re good to go!
Locating the Battery Compartment
Identifying the battery compartment in your Subaru key fob is crucial for a successful battery replacement. Here’s a detailed guide to help you locate it:
1. Ejecting the Key
Press the small button on the side of the key fob to release the key blade. Slide the key out completely.
2. Locating the Battery Compartment
Once the key is ejected, you’ll notice several small screws on the back of the key fob. Use a small Phillips head screwdriver to unscrew these screws carefully. Avoid using excessive force to prevent damage.
Once the screws are removed, carefully pry open the key fob’s housing. The battery compartment will be revealed inside the housing. It typically consists of a small plastic container with a metal cover. Note the orientation of the battery as you remove it, as it’s crucial for proper installation of the new battery.
| Model | Battery Compartment Location |
|---|---|
| Legacy (2005-2023) | Inside the housing, accessible by unscrewing the back |
| Impreza (2008-2022) | Inside the housing, accessible by sliding the back cover |
| Outback (1999-2023) | Behind a small door on the back, accessible by pressing a button |
| Ascent (2019-2023) | Inside the housing, accessible by removing the back cover |
| BRZ (2013-2021) | Inside the housing, accessible by sliding the back cover |
Inserting the New Battery
Locate the designated slot for the new battery inside the key fob. This slot is typically indicated by a small, spring-loaded latch or button. Gently press or slide the latch to release the current battery.
Position the new battery correctly within the slot, ensuring that the positive (+) and negative (-) terminals align with their respective contacts in the fob. Consult your vehicle’s owner’s manual or online resources for specific battery orientation details.
Carefully secure the new battery by pressing down on it or sliding the latch back into place. Ensure that the battery is firmly seated and not loose to prevent potential malfunctions.
Once the new battery is inserted, try pressing the key fob buttons to ensure proper functionality. If the keys do not respond, double-check the battery orientation and ensure secure contact. If the issue persists, consider replacing the battery again or consulting with a professional.
For added convenience, consult the following table for a step-by-step guide on inserting the new battery into your specific Subaru key fob:
| Step | Action |
|---|---|
| 1 | Locate the battery slot. |
| 2 | Press the battery latch. |
| 3 | Remove the old battery. |
| 4 | Insert the new battery. |
| 5 | Secure the battery by pressing down or sliding the latch. |
| 6 | Test the key fob buttons. |
Closing the Battery Compartment
Replacing the Battery Cover
Once the battery is securely in place, it’s time to replace the battery cover. Orient the cover correctly and slide it back into its slot. Ensure it fits snugly and securely closes the battery compartment.
Securing the Battery Compartment
After replacing the battery cover, inspect it to ensure it’s fully closed and locked. Some key fobs may have a small latch or button that needs to be pressed to secure the cover. Make sure this latch is engaged to prevent the cover from accidentally opening.
Verifying Compartment Closure
To verify if the battery compartment is securely closed, gently shake the key fob. If you hear any rattling or movement coming from the battery compartment, it may not be fully closed. Re-examine the cover and latch to ensure they’re properly engaged.
Testing the Key Fob Functionality
Before replacing the battery, it’s crucial to ascertain if the key fob is truly malfunctioning. Conduct the following steps to assess its functionality:
- Unlock the vehicle manually: Use the physical key to unlock the driver’s door.
- Insert the key into the ignition: Turn the key to the “ON” position, but do not start the engine.
- Press the lock button on the key fob: Observe if the vehicle’s doors lock and unlock in response.
- Press the unlock button on the key fob: Check if the doors unlock as well.
- Test the panic button (if applicable): Press the panic button and note if the vehicle’s horn sounds.
- Examine the key fob’s LED indicator (if applicable): When pressing buttons, observe if the LED lights up.
- Check the key fob’s battery level: Some key fobs feature a built-in battery level indicator. Consult your vehicle’s user manual for specific instructions.
- Try a spare key fob (if available): If you possess a spare key fob, insert it into the ignition and perform the same tests. This helps determine if the issue lies with the key fob or the vehicle’s receiving system.
| Symptom | Possible Cause |
|---|---|
| Key fob buttons not working | Weak or dead battery |
| Intermittent or delayed response from key fob | Insufficient battery power |
| Vehicle does not respond to key fob commands | Damaged or faulty key fob, or malfunctioning vehicle receiving system |
Proper Battery Disposal
Once you have replaced the battery in your Subaru key fob, it’s important to dispose of the old battery properly. Batteries contain hazardous materials that can be harmful to the environment if they are not disposed of properly. Check with your local authorities for information on how to properly dispose of batteries in your area. In some areas, you may be able to drop off batteries at a local recycling center or hardware store. You can also mail batteries back to the manufacturer for recycling. For more information, visit the battery industry’s website at http://www.batteryrecycling.org.
Steps for Proper Battery Disposal:
-
Check with local authorities: Contact your local waste management or environmental protection agency to find out the proper disposal methods for batteries in your area.
-
Recycle at collection points: Look for designated battery recycling bins or drop-off locations at local retailers, community centers, or recycling facilities.
-
Mail-back programs: Some battery manufacturers offer mail-back programs where you can send used batteries to them for safe disposal. Check the manufacturer’s website or packaging for details.
-
Dispose of as hazardous waste: If no other options are available, dispose of the battery as hazardous waste at a designated collection facility. Contact your local authorities for instructions.
-
Never dispose of batteries in the trash: Batteries should never be thrown away with regular household waste, as they can leach harmful chemicals into the environment.
-
Protect terminals: Cover or insulate the battery terminals with electrical tape or other non-conductive material to prevent short circuits and potential fires.
-
Transport safely: When transporting batteries for disposal, keep them separate from other items and secure them to prevent movement or damage.
-
Follow safety precautions: Always handle and dispose of batteries with caution, wearing gloves and eye protection if necessary.
-
Additional disposal considerations:
-
Button cell batteries: These small batteries commonly used in key fobs and watches contain mercury or silver oxide. Special care must be taken to follow the proper disposal method for these batteries.
-
Rechargeable batteries: Rechargeable batteries, such as lithium-ion or nickel-cadmium, require specific recycling processes to prevent environmental damage. Consult the manufacturer or battery recycling programs for proper disposal instructions.
-
Alkaline batteries: While not as hazardous as other types, alkaline batteries should still be disposed of properly to avoid environmental contamination. Recycle them at designated collection points or dispose of them as directed by your local authorities.
