Gather Your Tools


To open your Subaru key fob, you will need a screwdriver. It’s important to have a small Phillips head screwdriver that fits the screws on the back of the key fob. Using the wrong tool can damage the screws, making it difficult or impossible to open the key fob.

Disposable Gloves

Before handling the key fob, it’s a good idea to wear disposable gloves. This not only helps prevent fingerprints and smudges on the fob, but also protects your skin from any potentially harmful chemicals that may be present.

Clean Work Surface

When working on your key fob, it’s important to choose a clean and dry work surface that is free of any debris or dirt. This will help prevent any foreign particles from getting inside the key fob and damaging the internal components.

Step 1: Locate the Screws

Turn your key fob over to reveal the back where the screws are located. Take note of how many screws there are and their location.

Step 2: Remove the Screws

Using your screwdriver, carefully remove the screws from the back of the key fob. Be sure to keep track of the screws as you remove them, as they are small and easily lost.

Step 3: Open the Key Fob

Gently pry open the key fob using your fingers. If it’s difficult to open, you may need to use a small flathead screwdriver to gently pry it open. Be careful not to damage the internal components while opening the key fob.

Step 4: Replace the Battery or Make Repairs

Once the key fob is open, you can replace the battery or make any necessary repairs. To replace the battery, simply remove the old battery and insert a new one (make sure to check the battery type and size beforehand). For repairs, consult your owner’s manual or seek professional assistance.

Step 5: Reassemble the Key Fob

After replacing the battery or making repairs, reattach the back cover of the key fob and screw it back in place. Make sure the screws are tightened but not too tight, as over-tightening can damage the key fob.

By following these easy steps, you can safely open your key fob for battery replacement or repairs. Remember to always wear disposable gloves, use a clean work surface, and be careful not to damage the key fob while opening it.

Locate the Screws

If you need to replace the battery or simply want to take a closer look inside your Subaru key fob, you will first need to learn how to open it. Opening your key fob may seem daunting at first, but with a few simple steps, you can easily access the inside of your fob. In this article, we will guide you through the process of opening your Subaru key fob.

Turn the Fob Over

Firstly, you need to turn the key fob over, so the buttons face down. This will allow you to access the screws that hold the key fob together. Place the fob on a flat surface and ensure that you have enough light to see what you are doing. You may also want to clean your fob before you begin, as dust and debris can accumulate over time.

Locate the Screws

Using your Phillips head screwdriver, locate the screws on the back of the key fob. Subaru key fobs usually have two screws; one on the top and one on the bottom. The screws may be covered by a small rubber plug or simply visible on the back cover. Make sure

you have the right size screwdriver, so you don’t damage the screws.

Remove the Screws

Carefully unscrew the screws, making sure not to lose them. It’s a good idea to keep the screws in a small container or somewhere safe, so you don’t misplace them. Once you have removed the screws, use your fingers to gently separate the back cover from the front cover. Be careful not to pull too hard as you might damage any internal components.

Moreover, you may also want to use a plastic pry tool to gently separate the covers to ensure you don’t damage any components on the inside. If you find that the covers are hard to separate, double-check to make sure that you have removed all the screws.

Opening your Subaru key fob is a simple process that you can do at home with the right tools and instructions. Taking the time to learn how to open your key fob can save you time and money, especially if you need to replace the battery or a damaged component. So, follow these steps carefully, and explore the inside of your Subaru key fob.

How to Open Subaru Key Fob

Separate the Two Halves

To access the battery or address any issue you’re experiencing with the key fob, you need to separate the two halves first. You can do this by prying it open with your fingers or using a small flat head screwdriver.

When you do this, be sure to do it gently to avoid any damages to the fob. Start from the small gaps on the sides and work your way around the fob until the two halves are separated.

Be Careful with the Battery

Once the two halves are separated, you will have access to the battery and other components of the key fob. However, be extremely careful when handling the battery or any other parts inside the fob.

Avoid damaging the battery or any delicate component because it can cause severe damage to the fob; it may stop working entirely, and you don’t want to have to replace it.

Replace Battery or Address the Issue

Now that you have access to the battery and other parts inside the fob, you can replace the battery if it’s dead. If the issue isn’t related to the battery, you can address it and try to fix it yourself or take it to a professional.

When replacing the battery, ensure you take note of how the old one was inserted, so you can insert the new one correctly. Also, use the same type of battery as the one you’re replacing.

Once the issue has been addressed, snap the two halves of the fob back together. Press them together until you hear a clicking sound indicating they are locked in place.

In conclusion, opening a Subaru key fob is relatively easy, and with careful handling, you can do it without damaging the fob. Remember to follow the steps outlined in this article to ensure it’s done successfully.

Test the Key Fob

Before you call it a day, it’s important to test your key fob to ensure that it’s working properly. Press the buttons on the fob and check if all of them are working. If not, the problem may require further troubleshooting, or a visit to a mechanic.
