Step 4

Next, you will find metal contacts holding the battery in a fixed place. By applying gradual pressure, using a flathead screwdriver or butter knife carefully free the battery.

Step 5

Now that your old battery is out, it’s time to replace it with a new one. When you insert, ensure the positive side of the battery faces up while making the right metal contact for the best performance. Also, ensure the control module faces down on the battery icon on the house (plastic) when you return it.

Step 6

Place the second plastic on top of the other (housing the control module) and gently close it together. Return the internal key to its place.

Step 7

Test to confirm that your newly replaced Subaru key fob battery is working perfectly and you’re good to go!
