How To Change Subaru Car Key Battery

Have you ever had an experience where you had to press the unlock button on your key fob severally before it eventually responded and unlocked your car? The most likely reason is that the battery in your key fob has diminished and needs to be replaced soon.

If your key fob has suddenly stopped working, the most likely reason is that the battery is completely dead and needs to be replaced immediately. The battery is sealed inside the key fob to preserve its durability and prevent water from reaching its inner electric parts.

The first thing to note when replacing your Subaru car key battery is the type of battery it uses. The type of battery will vary depending on the year and model of your car. The most common types are the CR2032 and CR2025 3-Volt batteries, but you must consult your manual to confirm which one to buy.

Once you have the exact type of battery, all you need is a flathead screwdriver, a butter knife and some tape. Follow the step-by-step process highlighted below:

• Remove the mechanical key by pressing the button at the back of the fob with your thumb to take off the mechanical key.
• Open the housing of the fob to reveal the control module, and apply the screwdriver gently through the area where you removed the mechanical key to separate the housing into two.
• Lift out the control module gently and mark the housing that accommodates the control module.
• Use the butter knife to remove the battery from the metal contacts carefully.
• Insert the new battery
• Carefully return the control module to the housing.
• Cover the housing accommodating the control module.
• Return the Mechanical Key
• Test the Key Fob

If you followed all the steps highlighted above and your car key is still unresponsive, there may be an underlying issue with your car, and the next line of action is to get it to the nearest Subaru dealership.
