Identify The Battery Position

Before removing the old battery, you need to locate its position within the key fob. Generally, the battery in a Subaru key fob is located under the cover on the back of the fob. It may require a small screwdriver to access the battery compartment, but some models have a cover that can be easily pried open.

Check Battery Type And Voltage

To replace the battery in your Subaru key fob, the first step is to check the battery type and voltage. This simple procedure ensures that you use the correct replacement battery for optimal performance.

Check The Type Of The Battery

Before replacing the battery in your Subaru key fob, the first step is to check the type of battery it requires. Different key fobs may use different types of batteries, so it’s important to ensure you have the correct one.

You can usually find the type of battery required on the back of your key fob or in the owner’s manual. Look for a small label or engraved text that indicates the battery type. It may be something like CR2025 or CR2032.

If you can’t find the battery type on your key fob or in the manual, you can also try doing a quick online search using your key fob model and the words “battery type”. This should help you find the information you need.

Check The Voltage Of The Battery

Once you have determined the correct battery type for your Subaru key fob, the next step is to check the voltage. The voltage of the battery is equally important as using the wrong voltage can damage your key fob.

To check the voltage, you can use a multimeter. Set the multimeter to the DC voltage measurement setting and touch the positive (+) probe to the positive side of the battery and the negative (-) probe to the negative side of the battery.

The voltage reading should match the voltage specified on the battery or in the owner’s manual. For example, if the battery is labeled as 3V, the multimeter reading should be around 3 volts. If the voltage reading is significantly different, it’s best to find a battery with the correct voltage to ensure proper functioning of your key fob.

Remember, checking the type and voltage of the battery is crucial to ensure compatibility and avoid any potential damage to your Subaru key fob. Taking the time to perform these checks will save you from frustration and unnecessary expenses down the line.

Acquire A New Battery

To replace the battery in your Subaru key fob, first, locate the notch at the bottom of the fob and use a small screwdriver to pop it open. Then, remove the old battery and insert the new one, making sure the positive side is facing up.

Finally, snap the cover back in place, and your key fob should be good to go.

Purchase The Correct Battery Type

When it’s time to replace the battery in your Subaru key fob, the first step is to acquire a new battery. To ensure a hassle-free experience, it’s essential to purchase the correct battery type for your specific key fob model. Subaru key fobs typically require a CR2032 battery, but it’s always a good idea to double-check the battery type before making a purchase.

Ensure The Voltage Matches

Once you have identified the correct battery type, the next step is to ensure that the voltage matches. Subaru key fobs generally operate on 3 volts, so it’s crucial to select a battery with the same voltage. Using a battery with incorrect voltage can result in key fob malfunction or damage, so be sure to double-check the battery specifications before making a purchase.

Insert The New Battery

To ensure correct functionality of your Subaru key fob, it is essential to insert a new battery properly. Follow the steps below to replace the old battery with a new one.

Identify The Battery Position

Before replacing the old battery, you must first identify the position of the battery in your Subaru key fob. Look for the battery compartment on the back of the fob. It is usually a small rectangular or circular compartment that can be easily accessed.

Place The New Battery

Once you have identified the battery compartment, carefully open it using a small screwdriver or your fingernail. Remove the old battery and dispose of it properly. Now, take the new battery and place it in the same position, ensuring that the positive (+) and negative (-) signs on the battery match the diagram inside the compartment. Make sure the battery is firmly seated in the compartment.

Close The Key Fob

Once you have replaced the battery in your Subaru key fob, the next step is to close the key fob properly. It is essential to align the key fob halves correctly and then snap them together securely. To finish, just follow these steps:

Align The Key Fob Halves

  1. Hold the key fob in your hand, ensuring that the back cover is facing upward.
  2. Take the front cover of the key fob and align it with the back cover, making sure the buttons match up correctly.
  3. Check that the key ring loop at the top of the key fob is also aligned.
  4. Once aligned, carefully hold the front and back covers together to prevent them from moving.

Snap The Key Fob Together

  1. With the key fob halves properly aligned, it’s time to snap them together securely.
  2. Start by applying gentle pressure to the edges of the key fob, near the corners.
  3. Gradually move your fingers along the sides, applying equal pressure to ensure the key fob halves fit together tightly.
  4. Continue to snap the key fob together in a consistent motion until you reach the other end.
  5. Make sure you hear a satisfying click or snap sound, indicating that the key fob is securely closed.
  6. Inspect the key fob to ensure there are no gaps or misalignment between the front and back covers.

The key fob should now be completely closed and ready for use. It’s important to take your time during this process to avoid any damage or functional issues. Remember, a properly closed key fob will provide secure protection for your Subaru keys and ensure smooth operation.

Test The Key Fob

Testing the key fob is an essential step in replacing the battery in your Subaru key fob. It allows you to ensure that the battery replacement was successful and that your key fob is functioning properly. In this article, we will guide you through the process of testing your Subaru key fob after replacing the battery.

Press The Buttons

Once you have replaced the battery in your Subaru key fob, it’s time to test the buttons. Press each button one by one to verify that they are responsive and working as intended. This includes the lock, unlock, trunk release, and panic buttons.

Check For Proper Functioning

To confirm that your key fob is functioning correctly, you need to check if it performs the desired actions. Here are a few checks you can perform:

  • Stand near your vehicle and press the lock button on the key fob. The doors should lock, and you may hear a confirmation sound.
  • Press the unlock button on the key fob. The doors should unlock, and the interior lights may illuminate.
  • Try the trunk release button if your Subaru is equipped with one. The trunk should open smoothly.
  • Lastly, activate the panic button to test the alarm system. The car horn should sound, indicating that the panic function is working correctly.

If any of the buttons fail to elicit the desired response or if the key fob is unresponsive, it may indicate an issue with the battery replacement or a problem with the key fob itself. In such cases, you may need to repeat the battery replacement process or seek assistance from a Subaru dealership or a qualified locksmith.

Now that you have successfully tested your Subaru key fob after replacing the battery, you can rest assured that it is in good working condition. Remember to keep spare batteries on hand, so you’re always prepared for any battery-related issues that may arise in the future.

Tips And Precautions

When replacing the battery in your Subaru key fob, it’s essential to follow certain tips and precautions to ensure a smooth and safe process. These precautions will help you avoid potential mishaps and ensure the longevity of your key fob’s functioning. Here are a few key tips and precautions to keep in mind:

Double-check The Battery Position

Before proceeding with the battery replacement, ensure that you are placing the new battery in the correct position. Check the polarity and ensure that the positive (+) side of the battery is facing the designated direction. Placing the battery incorrectly can result in malfunctioning of the key fob, so it’s crucial to pay close attention to this detail.

Avoid Touching The Battery Terminals

When handling the battery, avoid direct contact with the battery terminals. Touching the terminals with your bare hands can leave residue on the battery, potentially affecting its performance. Utilize a clean cloth or gloves to handle the battery and avoid contamination. This precaution will help maintain the battery’s integrity and ensure optimal functioning of your key fob.

Common Key Fob Issues

The key fob is a convenient and essential accessory that allows you to unlock and start your Subaru vehicle with ease. However, like any electronic device, key fobs can encounter issues that may disrupt their functionality. In this section, we will discuss two common key fob issues: battery draining quickly and key fob not working.

Battery Draining Quickly

One of the most frustrating problems you may face with your Subaru key fob is a quickly draining battery. If you find yourself having to replace the battery frequently, there are a few possible reasons for this issue.

  • First, it’s important to check if there are any stuck buttons on your key fob. When a button gets stuck, it can continually send a signal, leading to battery drainage. To fix this, simply press each button several times to ensure they are not stuck.
  • Another possible cause of quick battery drain is a weak or dying battery. Over time, the battery in your key fob will naturally lose its charge. If you have already replaced the battery and the problem persists, consider using a high-quality battery specifically designed for key fobs to prolong its lifespan.
  • Lastly, interference from other nearby electronic devices can also drain the battery quickly. Try keeping your key fob away from other devices such as smartphones or tablets, as they can interfere with the signal and put a strain on the battery.

Key Fob Not Working

Another common issue with Subaru key fobs is when they stop working altogether. If your key fob is unresponsive, here are a few troubleshooting tips to help you get it working again.

  1. Start by checking the battery. A dead or low battery is often the culprit behind a non-functioning key fob. Replace the battery with a fresh one, ensuring you match the polarity correctly.
  2. If the battery replacement doesn’t solve the problem, try reprogramming the key fob. Each Subaru model may have a slightly different procedure, so consult your vehicle’s owner’s manual or refer to the manufacturer’s website for detailed instructions.
  3. In some cases, your key fob may need to be resynchronized with your vehicle. This can often be done using a provided process or by taking it to a Subaru dealership for assistance.

By following these troubleshooting steps, you can often resolve common key fob issues without the need for professional assistance. However, if you have tried these steps and your key fob still doesn’t work, it may be time to consult a Subaru technician who can diagnose and fix the problem for you.

Replacing Battery In Subaru Key Fob Vs. Dealer Replacement

When it comes to replacing the battery in your Subaru key fob, you have two options: doing it yourself or going to the dealer. While the dealer may seem like the obvious choice, there are several factors to consider before making your decision.

Cost Comparison

If you’re looking to save money, replacing the battery in your Subaru key fob yourself is the way to go. A dealer replacement can cost anywhere from $20 to $50, which can add up if you have multiple key fobs. On the other hand, buying a replacement battery at a local store or online will cost you only a fraction of that price, usually around $5 to $10.

Convenience

Convenience is another factor to consider when deciding between replacing the battery in your Subaru key fob yourself or going to the dealer. If you choose the dealer option, you’ll need to make an appointment, take time out of your day to drive to the dealership, and wait for the service technician to replace the battery. If you’re already pressed for time, this may become an even bigger problem.

On the other hand, replacing the battery yourself is straightforward and can be done in a matter of minutes. All you need is a small screwdriver and a replacement battery, which are readily available at most stores. Simply open the key fob, replace the old battery with the new one, and close it back up. It’s a quick and easy process that you can do on your own time, without having to leave your home.

Moreover, if you have multiple key fobs for your Subaru, it can be even more convenient to replace the batteries yourself. You can do them all at once and ensure that all your key fobs are ready to go, saving you time and effort in the future.

In conclusion, replacing the battery in your Subaru key fob yourself is not only cost-effective but also convenient. You can save money and time by avoiding a trip to the dealer and taking matters into your own hands. So, why not give it a try?

Other Key Fob Maintenance Tips

Aside from replacing the battery, there are several other key fob maintenance tips that can help prolong the life of your Subaru key fob.

Keeping The Key Fob Clean

Regularly cleaning your key fob can prevent dirt and debris from interfering with the key fob’s functionality. Wipe the key fob with a soft, dry cloth to remove any surface dirt or grime. In addition, using a small amount of isopropyl alcohol on a cloth can help effectively clean the key fob without causing damage. Avoid using water as it can seep into the key fob and damage the interior components.

Avoiding Extreme Temperatures

Exposing your key fob to extreme temperatures, whether hot or cold, can negatively impact its performance. Avoid leaving your key fob exposed to direct sunlight for extended periods. In cold weather, try to keep the key fob insulated to prevent issues with the battery and internal components.
