Thankfully, replacing the battery is a simple task that you can often handle yourself, saving you time and money. This comprehensive guide will walk you through everything you need to know about 2021 Subaru key fob battery replacement.
Understanding Your Subaru Key Fob
The 2021 Subaru models come equipped with a keyless entry system that uses a remote key fob to lock, unlock, and even start your vehicle. This fob operates on battery power, and like any battery, it will eventually lose its charge and need replacing.
Several signs might indicate your Subaru key fob battery is dying. These include:
- Decreased range: You find yourself standing closer to your vehicle to lock or unlock it.
- Intermittent functionality: The key fob works sometimes but not others, or you need to press the buttons multiple times.
- No response: The key fob fails to respond at all, even when you’re standing close to your vehicle.
What Battery Does a 2021 Subaru Key Fob Use?
Most 2021 Subaru key fobs utilize a CR2032 battery, a common type of lithium coin battery readily available at most electronics and auto parts stores.
