Billy Covington Do you own a Subaru car that uses a key fob for entry and ignition? If so, you know how convenient and essential it is to have a functional key fob. It allows you to lock and unlock your car from a distance, start your vehicle remotely, and more. However, what happens when your Subaru key fob stops working due to a dead battery? In this article, we will guide you through the steps to reset your Subaru key fob with a battery change, troubleshooting tips, and more.
The Importance of the Key Fob in Subaru Cars
Subaru key fobs are electronic devices that communicate with your car’s security system. They allow you to arm and disarm your car’s alarm, open your trunk, and, most importantly, start your car’s engine. The key fob transmits a unique signal to your car, allowing it to recognize the fob as authorized, and the car unlocks for the driver.
Without a functional key fob, you would have to manually unlock your vehicle and insert the key into the ignition to start your Subaru manually. Additionally, if you lose your key fob, you may have to replace the entire key fob programming, which can be time-consuming and expensive. Thus, it’s crucial to ensure that your key fob functions optimally and is always in good condition.
How to Know If Your Key Fob Battery Needs Changing
Before resetting your Subaru key fob, you must determine if the battery needs changing. Identifying that the key fob battery needs replacing is simple. When the battery power is running low, you may notice the following:
- The key fob’s range becomes shorter
- The key fob functions erratically or doesn’t work at all
- You notice a warning symbol on the dashboard
If you are experiencing any of the above issues, it’s time to replace your Subaru key fob battery.
