As a Subaru owner, you rely on your key fob to unlock your doors, start your engine, and even pop the trunk. But what happens when your key fob battery starts to die? Knowing how long your Subaru key fob battery lasts and how to spot the signs of a dying battery can save you from unexpected headaches.
Understanding Subaru Key Fob Battery Lifespan
Subaru key fob batteries typically last between 3 to 5 years, depending on factors like usage frequency, signal strength, and even weather conditions.
Frequent use can wear down the battery faster, just like excessive use drains your phone battery. Extreme temperatures, both hot and cold, can also impact battery performance.
Recognizing a Dying Subaru Key Fob Battery: Telltale Signs
A dying Subaru key fob battery often sends out warning signals. Recognizing these signs early on can save you from a lockout situation. Here are some common indicators:
- Decreased Signal Range: You find yourself standing closer to your Subaru to lock or unlock the doors.
- Intermittent Functioning: The key fob works sporadically, requiring multiple button presses.
- Warning Light on Dashboard: Your Subaru dashboard displays a “Key Fob Battery Low” warning.
- Delayed Response: Noticeable lag between pressing a button and your Subaru responding.
If you’re experiencing any of these issues, it’s a good idea to check if your Subaru key fob battery is low. Replacing the battery sooner rather than later can save you time and potential frustration.
Replacing Your Subaru Key Fob Battery: A Quick Guide
Replacing your Subaru key fob battery is a relatively straightforward process that you can often do yourself at home. Here’s a general guide, but remember to consult your owner’s manual for model-specific instructions:
-
Gather Your Supplies: You’ll need a small flat-head screwdriver and a replacement battery (typically a CR2032 or CR2025 3V lithium battery). You can easily find instructions to change the battery on your Subaru key fob online for your specific model.
-
Locate the Battery Compartment: Most Subaru key fobs have a small release button or notch on the back. Use your fingernail or the flat-head screwdriver to gently pry open the compartment.
-
Remove and Replace the Battery: Carefully remove the old battery, noting its orientation. Insert the new battery with the positive (+) side facing up, matching the old battery’s position.
-
Reassemble the Key Fob: Align the two halves of the key fob and press them firmly together until you hear a click.
