Understanding Your Denso Subaru Key Fob

Subaru utilizes key fobs manufactured by Denso, known for their reliability and advanced technology. These key fobs are crucial for accessing and operating your vehicle, including locking/unlocking doors, starting the engine, and activating the panic alarm. A dying Denso Subaru key fob battery can lead to intermittent or complete failure of these functions. Knowing how to address this issue is essential for every Subaru owner.

Identifying the Correct Denso Subaru Key Fob Battery

Before starting the replacement process, it’s crucial to identify the correct battery for your specific Denso Subaru key fob. Most Subaru key fobs use a CR2032 battery, a common type found in many electronics. However, it’s always best to double-check your owner’s manual or look for markings on the existing battery to confirm the correct type. Using the wrong battery can damage your key fob.

Gathering the Necessary Tools

Replacing a Denso Subaru key fob battery requires minimal tools. You’ll typically need a small flathead screwdriver or a similar tool to pry open the key fob casing. Some key fobs may have a small release button or slot instead.

Step-by-Step Guide to Replacing Your Denso Subaru Key Fob Battery

Here’s a detailed guide to replacing your Denso Subaru key fob battery:

1. Locate the key fob release: Look for a small notch, button, or slot on the side or back of the key fob. This is usually near where the key blade emerges.

2. Open the key fob casing: Carefully insert the flathead screwdriver into the notch and gently pry open the casing. Be careful not to damage the plastic.

3. Identify the battery compartment: Once the casing is open, locate the battery compartment. It usually holds the CR2032 battery securely in place.

4. Remove the old battery: Carefully remove the old battery. You can use the flathead screwdriver or your fingernails to pry it out.

5. Install the new battery: Insert the new CR2032 battery, ensuring the positive (+) side faces upwards, as indicated in the battery compartment.

6. Close the key fob casing: Align the two halves of the key fob casing and press them together until they snap shut.

7. Test the key fob: Try locking and unlocking your vehicle to ensure the new battery is working correctly.

Programming Your Denso Subaru Key Fob After Battery Replacement

In most cases, your Denso Subaru key fob will not require reprogramming after a simple battery replacement. The key fob should automatically reconnect with your vehicle’s system. However, if your key fob doesn’t function correctly after the battery replacement, you may need to consult your owner’s manual for specific reprogramming instructions or contact a Subaru dealership or a qualified automotive locksmith.

Common Issues and Troubleshooting

Sometimes, you may encounter issues even after replacing the battery. Here are a few common problems and solutions:

• Key fob still not working: Double-check that you’ve installed the correct battery type and that it’s positioned correctly. Try repeating the battery replacement process.

• Key fob functions intermittently: This could indicate a weak battery or a problem with the key fob’s internal circuitry. Try a new battery, and if the problem persists, consult a professional.

• Vehicle not responding to the key fob: Ensure there are no obstructions blocking the signal between the key fob and your vehicle. Try moving closer to the car.
