How to Charge Your Key Fob for Subaru

Knowing How To Charge Your Key Fob For Subaru can save you time and frustration. Many Subaru owners believe their key fobs need charging, similar to a smartphone. However, Subaru key fobs don’t actually require charging in the traditional sense. They operate on a small battery that needs replacing periodically.

Understanding Your Subaru Key Fob

Subaru key fobs are sophisticated pieces of technology. They use radio waves to communicate with your car, allowing you to lock, unlock, and even start your engine remotely. This functionality relies on a small battery inside the key fob. When this battery weakens, you might experience issues like reduced range or the key fob becoming completely unresponsive.

Do Subaru Key Fobs Really Need Charging?

No, they don’t. The confusion often arises because when a key fob’s battery is low, it behaves similarly to a device that needs charging. You might find yourself having to stand closer to the car for it to work, mimicking the limited functionality of a low-battery phone. However, the solution isn’t to plug it in, but to replace the battery. Check out our guide on subaru key fob battery replacement cost for more information about the expense involved.
