Are you having trouble with your 2009 Subaru Legacy key fob? Perhaps it’s stopped working, or maybe you’ve purchased a new or replacement key fob and need to get it programmed to your vehicle. The good news is, programming a 2009 Subaru key fob can often be done right at home without a trip to the dealership. This guide provides you with comprehensive, easy-to-follow instructions to program your 2009 Subaru Legacy key fob, saving you time and money.
Before you begin, ensure you have all your key fobs ready and are inside your 2009 Subaru Legacy with all doors and the rear gate or trunk lid completely closed. It’s important to follow these steps in quick succession, so read through the entire process once before starting.
Step-by-Step Programming Instructions for Your 2009 Subaru Key Fob
-
Driver’s Door Cycle: Open and close the driver’s side door one time.
-
Initiate Programming Mode: Within 45 seconds of the first door cycle, perform the following:
- Open and close the driver’s door again, one time.
- Insert your key into the ignition.
- Turn the ignition key from the LOCK position to the ON position rapidly 10 times within 15 seconds. You should hear an electronic tone sound once, followed by a continuous buzzing sound, and the interior lights will begin to flash. This indicates your Subaru is now in programming mode.
-
Confirm Entry into Programming Mode: Within 45 seconds of the tone and buzzing, open and close the driver’s door one more time within 15 seconds. An electronic tone should sound for 30 seconds. This confirms you are ready to program your key fob.
-
Enter the Transmitter Code: Locate the eight-digit code associated with your key fob. This code may be found on a label that came with your key fob, or inside the remote itself.
- While the electronic tone is sounding (from step 3), use the power door lock button on your door panel to input the first digit of your transmitter code. For example, if the first digit is ‘8’, press the LOCK button 8 times. If it’s ‘3’, press it 3 times, and so on.
- After entering the first digit, immediately (within five seconds) push the power door lock button to the UNLOCK side once.
- Repeat this process for each of the remaining seven digits of your transmitter code, always alternating between locking the door the number of times corresponding to the digit and then unlocking once after each digit.
-
Code Confirmation and Repetition: After entering all eight digits of the code for the first time, within 5 seconds, push the LOCK button to UNLOCK one time. Then, immediately repeat the entire process again, starting from the first digit and re-entering all eight digits of the code using the lock button, followed by an unlock after each digit. After entering the eighth digit for the second time, an electronic tone will sound for 30 seconds.
-
Finalization: Once the second electronic tone stops, remove the key from the ignition switch.
-
Test Your Key Fob: Test all the buttons on your newly programmed key fob to ensure they are working correctly with your 2009 Subaru Legacy.
Deleting Old Key Fob Codes
For security, especially if you have lost a key fob, it’s wise to delete the old transmitter codes from your Subaru’s memory. The system can store up to four key fob codes. To delete old codes, you must program four new codes. If you only have one or two working key fobs, you can program them multiple times to fill all four memory slots, effectively overwriting any old, unwanted codes.
- One Current Key Fob: Program it four times using the steps above.
- Two Current Key Fobs: Program each one twice.
- Three Current Key Fobs: Program two of them once, and the third one twice.
This process ensures that only your current, programmed key fobs will operate your vehicle’s keyless entry system.
Important Considerations
- Timing is Crucial: The programming sequence requires precise timing. If you miss a step or take too long between steps, the programming may fail, and you’ll need to start over. If you encounter errors multiple times, begin the procedure again from step 3.
- Avoid Interference: Ensure no one else is operating their keyless entry system within range of your vehicle while you are programming your key fob. This could potentially cause their transmitter code to be inadvertently programmed into your system.
- Code Accuracy: Double-check that you are entering the correct eight-digit transmitter code. If the code entered the second time does not exactly match the first time, an error will occur, and you will need to repeat the process.
By following these detailed instructions, you should be able to successfully program your 2009 Subaru Legacy key fob. Enjoy the convenience of your working remote! If you continue to experience difficulties, consider consulting a professional automotive locksmith or your local Subaru dealership for assistance.
