What Battery Does a Subaru Key Fob Use?
If you own a Subaru vehicle, you’re probably familiar with the convenience of using a key fob to lock and unlock your car. However, like any electronic device, the battery in your Subaru key fob will eventually run out of power. When that happens, you’ll need to replace the battery to ensure your key fob continues to function properly. In this article, we’ll explore what type of battery a Subaru key fob uses and provide you with all the information you need to replace it.
Understanding Key Fobs
Before we dive into the details of Subaru key fobs and their batteries, let’s quickly understand what a key fob is and how it works. A key fob, also known as a remote key or remote control, is a small electronic device that allows you to wirelessly control certain functions of your vehicle. These functions typically include locking and unlocking the doors, activating the panic alarm, and sometimes even starting the engine remotely.
Key fobs use radio frequency (RF) technology to communicate with your vehicle. When you press a button on the key fob, it sends a specific RF signal to the vehicle’s receiver, instructing it to perform a certain action. This wireless communication between the key fob and the vehicle relies on a battery to power the key fob transmitter.
Subaru Key Fob Batteries
Now that we have a basic understanding of how key fobs work, let’s focus on Subaru key fobs specifically. Subaru key fobs typically use a small, round battery known as a coin cell battery or button cell battery. The specific type of battery required may vary depending on the model and year of your Subaru vehicle.
The most common battery size for Subaru key fobs is CR2032. The “CR” in the battery name stands for lithium manganese dioxide chemistry, which is commonly used in small electronic devices due to its long life and stable voltage. The “2032” indicates the battery’s dimensions and capacity. CR2032 batteries are easily available and can be purchased at most hardware or electronics stores.
Replacing the Subaru Key Fob Battery
If you find that your Subaru key fob is not working or the range has significantly decreased, it’s likely time to replace the battery. Fortunately, replacing the battery in a Subaru key fob is a relatively simple task that you can do yourself. Here’s a step-by-step guide to help you through the process:
- Locate the battery compartment on your Subaru key fob. The compartment is usually located on the back of the key fob and can be accessed by removing a small cover.
- Use a small flathead screwdriver or a coin to gently pry open the battery compartment cover.
- Once the cover is open, you’ll see the old battery inside. Carefully remove the old battery from the compartment, taking note of its positive (+) and negative (-) sides.
- Clean the battery compartment with a soft cloth or a cotton swab to remove any dirt or residue.
- Insert the new battery into the compartment, ensuring that the positive side faces up.
- Close the battery compartment cover by aligning it with the key fob and pressing it firmly until it clicks into place.
After replacing the battery, test your Subaru key fob to ensure it is functioning correctly. If the key fob still doesn’t work, you may need to consult a Subaru dealership or a professional automotive locksmith for further assistance.
Extending the Battery Life
While replacing the battery in your Subaru key fob is a simple task, it’s always a good idea to try and extend the battery life for as long as possible. Here are a few tips to help you maximize the lifespan of your key fob battery:
- Avoid unnecessary button presses: Every time you press a button on the key fob, it consumes a small amount of battery power. Try to minimize the number of times you press the buttons, especially if they are not essential.
- Keep the key fob away from extreme temperatures: High temperatures can accelerate the discharge rate of the battery, while extremely low temperatures can affect its performance. Avoid leaving your key fob in a hot car or exposing it to freezing temperatures for extended periods.
- Replace the battery promptly: If you notice any signs of a weak or dying battery, such as reduced range or intermittent operation, replace the battery as soon as possible to prevent the key fob from completely failing.
By following these tips, you can help prolong the battery life of your Subaru key fob and avoid unexpected issues.
In conclusion, Subaru key fobs use a small coin cell battery, commonly the CR2032, to power their wireless functions. Replacing the battery is a straightforward process that can be done at home. By understanding the type of battery your Subaru key fob requires and following the steps outlined in this article, you can easily replace the battery and ensure your key fob continues to work reliably.
Remember to practice caution while replacing the battery and always handle the key fob with care. If you encounter any difficulties or the key fob still doesn’t work after replacing the battery, it’s recommended to seek professional assistance from a Subaru dealership or an automotive locksmith.
