Open the Key Fob

When it’s time to change the battery in your Subaru key fob, the first step is to open the casing. Here’s how you can do it easily:

  • Separate the Halves: Once you’ve loosened the casing, carefully work your way around the key fob to separate the two halves completely. Take note of any buttons or components that may fall out during this process.
  • Access the Battery: With the key fob open, you’ll have clear access to the battery compartment. Depending on the model, you may need to use tweezers or a small screwdriver to remove the old battery.
  • Replace the Battery: Identify the type of battery needed, usually CR2032, and insert the new battery with the correct orientation. Make sure it sits securely in the compartment.
  • Close the Key Fob: Once the new battery is in place, align the two halves of the key fob and press them together until you hear a satisfying click. Ensure that the casing is securely closed before testing the key fob.

Remember, taking your time and being gentle during the process will help you avoid any mishaps while changing the battery in your Subaru key fob.
