Understanding Your Subaru Key Fob
Before diving into the steps, it’s essential to understand the components of your Subaru key fob. Most Subaru models utilize a key fob that combines a physical key with electronic functionality. This electronic functionality allows you to lock and unlock your car, start the engine remotely, and even access other features like trunk release. The heart of this electronic system is the battery, which powers the key fob’s functions.
Types of Subaru Key Fobs
Subaru key fobs come in various shapes and sizes, but they generally fall into two main categories:
- Flip Key Fobs: These key fobs feature a physical key that flips out from the fob body. They are often found in older Subaru models.
- Remote Key Fobs: These key fobs are entirely button-operated and do not have a separate key blade. They are more common in newer Subaru models.
Identifying the Battery Type
The type of battery used in your Subaru key fob will vary depending on the model year and key fob design. Common battery types include CR2032, CR2025, and CR1616. You can usually find the battery type printed on the back of the key fob or in your owner’s manual.
Tools You’ll Need
Before you begin, gather the following tools:
- New Battery: Ensure you purchase a battery with the correct type and voltage for your Subaru key fob.
- Small Flathead Screwdriver: This will be used to pry open the key fob casing.
- Tweezers: These can be helpful for removing and inserting the battery.
