How To Change Battery Subaru Forester Key. Subaru key fob uses a battery that you can easily purchase online or at the store. Look for the flat round battery inside the fob.

The remote uses a CR2025 battery available from most major retailers and electronics stores. Youll need a flat head screwdriver steak knife or the key fob key. I assume this is the key fob.
The 2003 still had one drivers side key hole which the key can be used.
The process is the same for most Japanese car brands. I was given one key for my second hand 03 Forester from a Subaru car yard 5 years ago. Take out the emergency key. Put the new 2032 battery in its place in the same direction as the old battery.
