Identifying Your Subaru Key Fob Model

Before you embark on the journey of replacing the battery in your Subaru key fob, it is crucial to first determine the specific model you own. Subaru has utilized several different key fob designs over the years, each of which may require a slightly different approach when it comes to battery replacement. Identifying your model correctly ensures you purchase the correct battery and follow the appropriate steps for replacement.

To start, locate your vehicle’s ownership manual, where you can find details about the key fob. If you no longer have access to the manual, a quick inspection of the key fob itself can be telling. Look for any model numbers or distinctive features. Common models include the traditional rectangular fob with lock, unlock, trunk, and panic buttons; newer models might have a sleeker design with added features like a display screen.

Another method is checking the back of the key fob. Often, there will be a small sticker or engraving indicating the model number. If your key fob is newer and supports features like remote start, it may belong to a different series compared to older, more basic fobs.

If visual inspection doesn’t yield results, visiting the Subaru website or contacting a local dealer can be helpful. Provide them with your VIN (Vehicle Identification Number), and they can tell you exactly which key fob model corresponds to your vehicle. Knowing the precise model of your Subaru key fob not only helps in buying the right battery but also aids in following the correct replacement procedure, thereby avoiding any potential damage to the fob.

Tools and Materials Needed

To successfully change the battery in your Subaru key fob, you’ll need to gather a few tools and materials beforehand. Having these items on hand will make the process much smoother and ensure that you can complete the task without any interruptions:

  • A small flathead screwdriver or a plastic pry tool: This will help you open the key fob without causing any damage to the casing.
  • A replacement battery: Make sure to check your Subaru key fob model to determine the correct battery type needed.
  • Clean cloth or microfiber towel: To wipe down the key fob and ensure no dirt or debris interferes with the battery replacement.
  • Tweezers: Useful for handling the small battery and placing it securely in the key fob.
  • Optional: Gloves to protect your hands and prevent any accidental contact with dirt or chemicals during the process.

By having these tools and materials ready, you can efficiently change the battery in your Subaru key fob and maintain the functionality of your keyless entry system.

Step-by-Step Guide to Replacing the Battery

When it comes to replacing the battery in your Subaru key fob, it’s essential to follow a systematic approach to ensure a smooth and successful process. Here is a step-by-step guide to help you replace the battery in your Subaru key fob:

  1. Locate the Battery Compartment: Begin by identifying the battery compartment on your Subaru key fob. This is usually located on the back of the key fob and can be accessed by pressing a release button or sliding off a cover.
  2. Remove the Old Battery: Carefully remove the old battery from the compartment using a small flat-head screwdriver or a coin to gently pry it out. Be cautious not to damage the key fob casing during this step.
  3. Clean the Battery Compartment: Before inserting the new battery, take a moment to clean the battery compartment using a dry cloth or a cotton swab to remove any dirt or debris that may have accumulated.
  4. Insert the New Battery: Take the new battery, ensuring it is the correct type and size for your Subaru key fob. Insert the new battery into the compartment with the positive(+) and negative(-) sides facing the correct direction as indicated.
  5. Close the Battery Compartment: Once the new battery is securely in place, gently close the battery compartment cover or slide it back into position until it clicks shut. Ensure that the cover is properly sealed to prevent any water or dust from entering.
  6. Test the Key Fob: Test the functionality of your Subaru key fob by pressing the buttons to lock and unlock your vehicle. If the key fob responds as expected, the battery replacement was successful.

Following these steps carefully will help you replace the battery in your Subaru key fob efficiently and maintain the functionality of your key fob.

Finding the Right Battery for Your Subaru Key Fob

When it comes to replacing the battery in your Subaru key fob, selecting the right battery is crucial to ensure proper functioning of your key fob. The specific type of battery required can vary depending on the model and year of your Subaru vehicle.

To find the right battery for your Subaru key fob, the first step is to identify the model of your key fob. As discussed earlier, different Subaru key fob models may have varying battery requirements. Once you have determined the model of your key fob, you can refer to the owner’s manual of your Subaru vehicle for detailed information on the type of battery needed.

Typically, Subaru key fobs use coin cell batteries, also known as lithium batteries. These batteries are commonly available at electronics stores, hardware stores, or even online retailers. It is important to check the specifications of the battery to ensure it matches the requirements of your Subaru key fob.

When purchasing a replacement battery for your Subaru key fob, make sure to opt for a high-quality battery from a reputable brand. Using a reliable battery will help prolong the lifespan of your key fob and prevent issues such as short battery life or malfunctioning of the key fob.

If you are unsure about the specific type of battery needed for your Subaru key fob, you can also consult with a Subaru dealership or a professional locksmith. They can provide you with the necessary information and help you find the right battery for your key fob.

Safety Precautions When Changing Key Fob Batteries

When it comes to replacing the battery in your Subaru key fob, safety should always be a top priority. While changing the battery is a relatively simple task, there are some precautions you should keep in mind to ensure the process goes smoothly and without any issues.

First and foremost, make sure to work in a well-lit area with enough space to maneuver comfortably. It’s essential to have a clear workspace free of clutter to prevent any small components from getting lost or misplaced during the battery replacement process.

Before you begin, it’s wise to gather all the necessary tools and materials needed for the task. This includes the new battery, a small flat-head screwdriver or a coin for opening the key fob, and possibly a pair of tweezers for handling the battery.

One crucial safety precaution to remember is to handle the key fob with care. Avoid applying excessive force when opening the key fob to prevent any damage to the casing or internal components. Additionally, be mindful of any sharp edges on the key fob that could cause injury if handled carelessly.

When removing the old battery from the key fob, take care not to touch the battery terminals with your bare hands. Oils and dirt from your skin can potentially affect the battery’s performance or cause it to malfunction prematurely. It’s recommended to use a pair of gloves or a clean cloth to handle the battery during the replacement process.

As you insert the new battery into the key fob, ensure it is facing the correct direction as indicated in the manufacturer’s instructions. Improperly inserting the battery can prevent the key fob from functioning correctly and may require you to repeat the battery replacement process.

After replacing the battery, carefully reassemble the key fob, ensuring all components are aligned correctly before snapping the casing back together. Take your time to avoid any accidental damage to the key fob or its internal components.

Lastly, test the key fob to verify that the new battery is functioning correctly. Press the buttons on the key fob to check if it locks and unlocks the vehicle as expected. If the key fob is not responding after battery replacement, double-check the battery installation and consult the troubleshooting section in this guide for further assistance.

Troubleshooting Common Issues After Battery Replacement

After replacing the battery in your Subaru key fob, you may encounter some common issues that can be easily resolved with a few troubleshooting steps.

One common issue is that the key fob may not work even after replacing the battery. In such cases, make sure the battery is properly installed with the correct polarity. Double-check that the battery contacts are clean and free of any debris or corrosion that may be obstructing a proper connection.

If your Subaru key fob still doesn’t function after checking the battery, try reprogramming it. Reprogramming your key fob is a simple process that can often resolve any connectivity issues. Refer to your Subaru owner’s manual for specific instructions on how to reprogram your key fob.

Another issue you may encounter is a weak signal or range from the key fob after replacing the battery. This could be due to interference from other electronic devices or a physical obstruction. Try standing closer to your Subaru or moving away from potential sources of interference to see if the signal improves.

If your key fob buttons are not responding as they should after battery replacement, there may be a need to reset the key fob. This can usually be done by pressing certain button combinations in a specific sequence. Again, consult your owner’s manual for guidance on how to reset your Subaru key fob.

In some cases, a faulty key fob may require professional repair or replacement. If you have tried troubleshooting the issues with your Subaru key fob to no avail, it may be time to seek assistance from a qualified automotive locksmith or Subaru dealership.

By following these troubleshooting tips, you can address common issues that may arise after replacing the battery in your Subaru key fob and ensure that it continues to operate smoothly.

How to Properly Dispose of Old Key Fob Batteries

When it comes time to replace the battery in your Subaru key fob, it’s essential to also consider how to properly dispose of the old battery. Key fob batteries contain materials that can be harmful to the environment if not disposed of correctly. To ensure that you are being environmentally responsible and following the proper guidelines, here are some steps to help you dispose of old key fob batteries safely:

  1. Firstly, check with your local recycling center or electronic waste disposal facility to see if they accept small batteries like the ones found in key fobs. Many communities have specific drop-off locations for batteries to ensure they are disposed of properly.
  2. If your local recycling center does not accept small batteries, consider participating in a community hazardous waste collection event. These events are designed to safely collect and dispose of items like batteries, paint, and other potentially harmful materials.
  3. Some electronic stores and retailers also have battery recycling programs where you can drop off old batteries for proper disposal. Check with stores like Best Buy or Home Depot to see if they offer battery recycling services.
  4. Another option is to contact the manufacturer of your key fob or the retailer where you purchased it to inquire about their battery disposal program. They may have information on how to safely dispose of old key fob batteries.
  5. Never throw key fob batteries in the trash as they can leak harmful chemicals into the environment. It’s important to handle and dispose of these batteries with care to protect both the environment and your health.

By following these steps and properly disposing of your old key fob batteries, you can help reduce the impact of electronic waste on the environment and ensure that hazardous materials are handled safely.

Reprogramming Your Subaru Key Fob After Battery Change

After successfully changing the battery in your Subaru key fob, the next crucial step is reprogramming it to ensure it functions properly with your vehicle. Reprogramming the key fob is a straightforward process that typically requires you to synchronize the key fob with your car’s receiver.

To reprogram your Subaru key fob after a battery change, you will need to follow these general steps:

  1. Enter your car with the new battery-installed key fob and make sure all doors are closed.
  2. Insert the key into the ignition and turn it to the “On” position without starting the engine.
  3. Press and hold the “Lock” button on the key fob for a few seconds and then release it.
  4. Repeat this process a few times until you see the car’s lights flash or hear a chime, indicating that the key fob has been successfully reprogrammed.
  5. Remove the key from the ignition and test the key fob to ensure it locks and unlocks the doors as expected.

If you encounter any issues during the reprogramming process, refer to your car’s manual for specific instructions or consider seeking assistance from a professional locksmith or your Subaru dealership.

It’s important to note that the reprogramming process may vary slightly depending on the model and year of your Subaru vehicle. Always refer to the manufacturer’s guidelines to ensure you are following the correct steps for your specific key fob and car model.

By reprogramming your Subaru key fob after a battery change, you can avoid potential issues with keyless entry and ensure that your key fob operates smoothly and securely with your vehicle.

Cost Considerations for DIY Battery Replacement

When it comes to the cost considerations for DIY battery replacement in your Subaru key fob, there are a few factors to keep in mind. While changing the battery yourself can be a cost-effective option compared to visiting a dealership or locksmith, it’s essential to consider the expenses involved in the process.

One of the primary cost considerations for DIY battery replacement is the price of the replacement battery itself. Depending on the type and brand of battery required for your Subaru key fob, the cost can vary. It’s advisable to opt for high-quality batteries to ensure optimal performance and longevity.

Additionally, you may need to invest in specific tools or materials to complete the battery replacement process successfully. While some key fobs can be opened using simple tools like screwdrivers, others may require more specialized equipment. Factoring in the cost of these tools is essential to determine the overall expense of the DIY replacement.

Moreover, if you encounter any issues during the battery replacement process and require professional assistance, there might be additional costs involved. In such cases, seeking help from a locksmith or dealership to rectify the problem could result in extra expenses that should be considered in your budget.

On the other hand, opting for a DIY battery replacement can potentially save you money in terms of labor costs. By following a step-by-step guide and performing the replacement yourself, you can avoid paying service fees typically charged by technicians for similar tasks.

It’s crucial to weigh the overall costs of DIY battery replacement against the benefits of convenience and savings it offers. While it may require an initial investment in batteries and tools, the long-term cost-effectiveness of maintaining your Subaru key fob through DIY replacements can outweigh the expenses incurred.

Benefits of Regular Key Fob Maintenance

Regular maintenance of your Subaru key fob is crucial for ensuring its optimal performance and longevity. By incorporating key fob maintenance into your routine, you can prevent unexpected issues and extend the lifespan of your key fob.

One of the key benefits of regular key fob maintenance is that it helps to identify any potential problems early on. By routinely inspecting and cleaning your key fob, you can spot any signs of wear and tear, corrosion, or damage that may affect its functionality. Addressing these issues promptly can prevent more serious problems down the line and save you time and money on repairs.

In addition, regular maintenance can help to preserve the battery life of your key fob. By keeping the key fob clean and free of debris, you can ensure that the battery connections remain strong and reliable. This can prevent intermittent issues with the key fob not working or needing frequent battery replacements.

Maintaining your key fob also contributes to its overall security and convenience. A well-maintained key fob is less likely to malfunction or fail, reducing the risk of being locked out of your vehicle or experiencing other inconveniences. Additionally, a properly functioning key fob provides peace of mind knowing that you can easily access your car and secure it with the touch of a button.

Regular maintenance of your key fob is a simple yet effective way to protect your investment in your Subaru vehicle. By dedicating a few minutes to inspecting and cleaning your key fob regularly, you can enjoy reliable performance and convenience for years to come.

How to Extend the Life of Your Key Fob Battery

One of the key ways to extend the life of your key fob battery is to minimize unnecessary usage. While it may seem convenient to repeatedly press the buttons on your key fob, doing so can drain the battery faster. Try to be mindful of how often you use your key fob and only press the buttons when necessary.

Additionally, keeping your key fob away from extreme temperatures can help prolong the battery life. Batteries tend to drain faster in both very hot and very cold conditions. Avoid leaving your key fob in the car on a hot summer day or in freezing winter temperatures for extended periods.

Regularly cleaning your key fob can also contribute to extending the battery life. Dust, dirt, and grime can accumulate on the buttons or inside the key fob, affecting its functionality and potentially draining the battery faster. Use a soft cloth or a small brush to gently clean the key fob and prevent any buildup that could impact its performance.

Another effective way to extend the life of your key fob battery is to replace it before it completely runs out of power. Keep track of how long you’ve been using the current battery and proactively replace it at regular intervals, even if it still seems to be working. This preventive measure can help avoid sudden key fob failures due to a depleted battery.

Lastly, storing your key fob properly when not in use can also help maintain the battery life. Keep it in a secure location away from other electronic devices that might interfere with its signal or drain the battery unintentionally. By taking these simple steps, you can ensure that your key fob battery lasts longer and reduces the frequency of replacements.

Professional vs. DIY Battery Replacement: What’s Best?

When it comes to replacing the battery in your Subaru key fob, you may be faced with the decision of whether to opt for a professional service or to tackle the task yourself. Both options have their own set of advantages and considerations to keep in mind.

Professional battery replacement services can offer convenience and peace of mind, especially if you are not comfortable or familiar with working on electronic devices. Technicians at dealerships or auto locksmiths have the expertise and tools necessary to efficiently replace the battery in your Subaru key fob.

On the other hand, opting for a DIY battery replacement can save you time and money. With the right tools and guidance, changing the battery in your Subaru key fob can be a straightforward process. DIY enthusiasts may also enjoy the satisfaction of successfully completing the task on their own.

Before deciding between professional and DIY battery replacement, consider factors such as your comfort level with electronics, availability of tools, and budget. If you are confident in your abilities and have the necessary tools at hand, DIY replacement may be the preferred choice. However, if you prefer the assurance of professional expertise or lack the time to perform the replacement yourself, seeking professional help can be the way to go.
