Having issues programming a new key fob for your 2009 Subaru Forester? You’re not alone. Many Subaru owners encounter challenges when trying to add or replace their key fobs, especially with aftermarket or used options. This guide aims to provide a clear, step-by-step approach to programming a 2009 Subaru Forester key fob, along with troubleshooting tips to overcome common hurdles.
Understanding Your 2009 Subaru Forester Key Fob
The 2009 Subaru Forester typically uses a teardrop-shaped key fob with four buttons: Lock, Unlock, Panic (red), and Liftgate. These fobs, often manufactured in Japan, usually have an FCC ID of NHVWB1U711 and IC 3495A-WB1U71 printed on the back for identification. Ensuring your replacement fob matches these specifications is a crucial first step in the programming process. Using a compatible fob significantly increases your chances of successful programming.
Step-by-Step Programming Guide for Your 2009 Subaru Forester Key Fob
While the process is often described as DIY-friendly, it requires precise execution. Here’s a detailed breakdown of the programming steps for a 2009 Subaru Forester key fob:
- Get in the Driver’s Seat: Ensure all doors are closed but unlocked. You will need to remain in the driver’s seat throughout the procedure.
- Door Cycling: Open and close the driver’s door. This action initiates the programming sequence.
- Ignition Cycling: Turn the ignition key from the “Off” position to the “On” position and back to “Off” rapidly ten times. You should hear an interior chime and see the dome lights flashing, indicating entry into programming mode.
- Door Cycling (Confirmation): Open and close the driver’s door again. You should hear an additional exterior chime, confirming the system is ready to learn a new key fob code.
- Code Entry: This is where things get a bit tricky. Locate the 8-digit top number inside your key fob. You will use a Morse code-style method to input this code using the unlock button. Each digit is entered by pressing the unlock button a corresponding number of times (e.g., one press for ‘1’, two presses for ‘2’, etc.). After each digit entry, briefly pause.
- Repeat Code Entry: Repeat step 5 to enter all eight digits of the code.
- Confirmation: After entering the 8th digit and pressing the unlock button, the car locks should cycle (lock and unlock) to signal successful code entry and programming completion.
Troubleshooting Common 2009 Subaru Forester Key Fob Programming Issues
Many users, like in the original scenario, encounter problems even after meticulously following these steps. Here are some common issues and troubleshooting tips:
- Locks Not Cycling: This is a frequent point of failure. If the locks don’t cycle after code entry, it might indicate an issue with the code input, timing, or fob compatibility. Double-check the 8-digit code and ensure precise button presses during code entry. Restart the process from step 1 if necessary.
- Used Fobs Not Working: While used OEM fobs can be programmed, they might sometimes be problematic. Ensure the used fob is indeed compatible with your 2009 Forester (FCC ID, IC number match). Battery condition is crucial; even if a battery tests “fine,” a slightly weak battery can hinder programming. Try a fresh, high-quality battery.
- Door Lock Mechanism Issues: In the original post, a jammed driver’s door keyhole was mentioned. While seemingly unrelated to fob programming, issues with door lock mechanisms or sensors might interfere with the programming sequence. Ensure all doors are properly closed and that the door lock switch inside the car functions correctly.
- Incorrect Procedure: Timing and precise execution are critical. Review each step carefully and ensure you are performing the actions correctly, especially the ignition and door cycling steps. Watch videos online demonstrating the process for visual guidance.
- Code Rejection: While it’s generally believed any 8-digit code could be entered, the system might have some validation parameters. However, the primary issue is usually code entry accuracy rather than code rejection. Focus on correctly entering the code from your fob.
When to Seek Professional Help
If you’ve tried these steps and troubleshooting tips multiple times and still cannot program your 2009 Subaru Forester key fob, it might be time to seek professional assistance. Subaru dealerships and specialized automotive locksmiths possess advanced diagnostic tools and expertise to program key fobs, even in cases where DIY methods fail. While it might incur a cost, professional programming ensures compatibility and can save you from further frustration.
Programming a 2009 Subaru Forester key fob can be a rewarding DIY task. By understanding the process, ensuring fob compatibility, and carefully following the steps, you can often successfully program a new or replacement fob. However, being aware of potential issues and knowing when to seek professional help is equally important. For more automotive key fob programming guides and solutions, visit keyfobprog.com.
