Identifying the Key Fob Type

How to Change the Battery in My Subaru Key Fob

When it comes to changing the battery in your Subaru key fob, the first step is to identify the type of key fob you have. Subaru key fobs come in different shapes and sizes, so it’s important to know which one you have before you begin the battery replacement process.

One way to identify the key fob type is to look for any markings or labels on the key fob itself. Some key fobs have the model number or brand name printed on them, which can help you determine the type of key fob you have. If you’re still unsure, you can always refer to your Subaru owner’s manual for guidance on identifying the key fob type.

Another method for identifying the key fob type is to check the key fob for any buttons or features that are unique to a specific model. For example, some Subaru key fobs have a built-in key blade that can be used to manually unlock the car door, while others may have a remote start feature. By taking note of these features, you can narrow down the type of key fob you have and proceed with the battery replacement accordingly.

Opening the Key Fob Case

One of the first steps in replacing the battery in your Subaru key fob is to open the key fob case. To do this, you will need to locate the small indentation on the side of the key fob. This is where you will insert a flathead screwdriver in order to gently pry apart the two halves of the key fob case.

Once you have located the indentation, carefully insert the screwdriver and begin gently prying the key fob case apart. It’s important to be cautious and gentle during this process in order to avoid damaging the key fob or the case itself. Take your time and slowly work your way around the entire perimeter of the key fob case until it begins to separate.

As the two halves of the key fob case start to come apart, be mindful of any small parts or pieces that may be inside. It’s important to keep track of everything as you don’t want to lose any pieces during the battery replacement process. Once the key fob case is open, you will have access to the old battery as well as the circuit board inside the key fob.

Replacing the Old Battery

When it comes time to replace the old battery in your Subaru key fob, it’s important to have the right tools and know the proper steps to take. First, you’ll need to identify the type of key fob you have, as different models may have different methods for replacing the battery. Once you have determined the type of key fob you have, you can then move on to opening the key fob case.

Using a small flathead screwdriver or a coin, carefully pry open the key fob case. Be sure to do this gently to avoid damaging the case or any internal components. Once the case is open, you can locate the old battery and carefully remove it using the same tools. Take note of the orientation of the old battery so that you can insert the new battery correctly.

After removing the old battery, it’s time to insert the new one. Make sure the new battery is the correct type and size for your key fob model. Once the new battery is in place, test the key fob to ensure it is working properly. If everything is functioning as it should, close the key fob case by carefully snapping the two halves back together.

Testing the New Battery

After successfully replacing the old battery in your Subaru key fob, the next step is to test the new battery to ensure it is functioning properly. Testing the new battery is a crucial part of the process as it will determine whether the key fob is now ready to be used.

One way to test the new battery is to simply press the buttons on the key fob to see if it responds. If the key fob lights up and the buttons work as they should, then the new battery is likely working correctly. However, if the key fob does not light up or the buttons are unresponsive, it may indicate that the new battery is either inserted incorrectly or faulty.

Another method to test the new battery is to use a battery tester to measure its voltage. A healthy battery should have a voltage reading within the specified range for the key fob model. If the voltage reading is outside of this range, it may indicate that the new battery needs to be replaced again.

Closing the Key Fob Case

Once you have successfully replaced the old battery in your Subaru key fob, it is time to close the key fob case. Make sure the battery is securely in place and then carefully line up the two halves of the key fob case. Take your time to ensure that the case is closed properly to avoid any potential damage to the internal components of the key fob.

Press the two halves of the key fob case together firmly until you hear a click, indicating that the case is securely closed. Be sure to apply even pressure along the edges of the case to ensure that it is fully closed and sealed. It is important to make sure that the key fob case is properly closed to protect the battery and internal circuitry from any moisture or dirt that could potentially cause damage.

After closing the key fob case, test the key fob to make sure that it is functioning properly. Press the buttons to ensure that the key fob is transmitting signals effectively. If everything is working as it should, congratulations – you have successfully replaced the battery in your Subaru key fob and closed the case!
