Step-by-Step Battery Replacement Guide
Follow these steps to replace the battery in your Subaru Ascent key fob:
Step 1: Locate the Indentation
First, find the small indentation on the corner of the key fob. This is where you will insert the flathead screwdriver to open the device.
Step 2: Insert and Turn the Screwdriver
Insert the flathead screwdriver into the indentation and turn it as if you were turning a key. This action will begin to separate the two halves of the key fob.
Step 3: Open the Key Fob
Once the key fob starts to open, use the screwdriver to twist and work your way down the opening. Continue until the back piece of plastic comes off completely. Set this piece aside.
Step 4: Remove the Button Housing
Inside the key fob, you’ll find the button housing, which also contains the battery. Carefully dump out this part to expose the battery.
Step 5: Target the Plastic Pieces
Several small plastic pieces hold the battery in place. Use the flathead screwdriver to target these pieces one by one. Pry them up gently to avoid damaging the components.
Step 6: Remove the Old Battery
With the plastic pieces loosened, you can now remove the old CR1620 battery. Use the corner of the flathead screwdriver to lift the battery out from its slot.
Step 7: Insert the New Battery
Take a new CR1620 battery and ensure the positive side (with text and battery information) faces down. Click the new battery into place.
Step 8: Reassemble the Key Fob
Reassembling the key fob is much easier than taking it apart. Line up all the components and click them back together. Ensure the button housing and back piece are securely in place.
Step 9: Test the Key Fob
Finally, test the buttons on your key fob to make sure everything works correctly. If the buttons respond as expected, you’ve successfully replaced the battery.
