Is your Subaru key fob acting up, or did you get a replacement that needs programming? Many Subaru owners find themselves pondering whether they can tackle the key fob programming process themselves. For those with the latest Subaru models, it’s typically necessary to visit an authorized Subaru dealership service center for programming. However, if you own a slightly older Subaru, you might be in luck! Programming your key fob right in your driveway could be a feasible DIY task. Subaru experts are here to guide you through the steps of programming your Subaru key fob at home.
Decoding Your Subaru Key Fob: Programmable vs. Dealership-Dependent
Before diving into the programming steps, it’s crucial to identify the type of key fob your Subaru uses. The good news is that Subaru often employs a teardrop-shaped key fob that is designed for owner programming. Take a look at your key fob; if it matches this description, you’re likely able to program it yourself by following the instructions below. If you have a newer, more advanced key fob, or are unsure, checking your owner’s manual or contacting a Subaru dealership is always a good first step.
Step 1: Unlocking Your 8-Digit Subaru Key Fob Programming Code
The first hurdle in programming your Subaru key fob is retrieving the unique 8-digit code embedded within the fob itself. Don’t worry, this isn’t as complicated as it sounds! Here’s how to find it:
- Access the Circuit Board: Carefully open the key fob case. This usually involves a small screw or clasp, depending on your model. Gently separate the two halves of the case to expose the transmitter circuit board inside.
- Locate the 8-Digit Code: Examine the transmitter circuit board. You’ll be looking for one or two sets of numbers, each containing 8 digits. These are often printed directly on the board.
- Record the Code: Write down the first 8-digit number series you see. This is your programming code, and you’ll need it shortly.
- Reassemble the Fob: Carefully snap the key fob case back together, ensuring it’s securely closed.
- Prepare Your Subaru: Get comfortable in the driver’s seat of your Subaru. Make sure all doors are completely closed, and the ignition is turned off.
Step 2: Programming Your Subaru Key Fob: Entering the Code
Now that you have your 8-digit code, it’s time to program your Subaru key fob to communicate with your vehicle. This process requires a bit of speed and precision, so read through these steps carefully before you begin:
- Driver’s Side Door Prep: Open the driver’s side door. Use the door button control to unlock all the doors. Then, close the driver’s side door again.
- Ignition Sequence Initiation: Insert your key into the ignition.
- On-Off Cycle (x10): This is the crucial step. Quickly turn the ignition key to the “ON” position (just before starting the engine, engaging the electrical systems) and then immediately back to the “OFF” position. Repeat this “ON-OFF” cycle ten times in rapid succession. Speed is key here!
- Chime Confirmation #1: If you’ve performed the ignition sequence correctly, the instrument panel will emit a chime sound after the tenth cycle. This is your signal to proceed.
- Door Open/Close & Chime #2: Open and then close the driver’s side door again. You should hear a second chime sound, and you’ll likely see the vehicle’s dome lights flash briefly.
- Programming Window Opens: At this point, the vehicle’s computer has entered programming mode. You now have approximately 45 seconds (indicated by a continuous chime) to input your 8-digit transmitter number using the door lock/unlock buttons.
Step 3: Entering the 8-Digit Code via Lock/Unlock Buttons
With the programming window open, you’ll use the lock and unlock buttons on the driver’s side door to digitally enter your 8-digit code. Here’s how:
- Locate Lock/Unlock Buttons: Find the lock and unlock buttons on your driver’s side door panel, usually positioned near the power window controls.
- Digit-by-Digit Entry: Focus on the first digit of your 8-digit code. Press the “lock” button the number of times corresponding to that digit. For example, if the first digit is ‘3’, press the lock button three times. Immediately after pressing the lock button(s), press the “unlock” button once. This action registers the digit you just entered and moves to the next digit in the sequence.
- Repeat for All Digits: Repeat step 2 for each of the eight digits in your code sequence, moving from the first digit to the last. Remember to press the “unlock” button once after each digit’s lock button presses.
- Confirmation Chime (External): After you’ve entered all eight digits, listen carefully. You should hear a chime sound coming from outside the vehicle. This confirms that the code sequence has been successfully entered.
- Verification Sequence: To ensure accurate entry, repeat steps 2 and 3 one more time, entering the entire 8-digit sequence again. If the second entry is also correct, you will hear the vehicle’s locking system engage with an audible “click.”
- Final Steps & Testing:
- Open and close the driver’s door one last time.
- Press either the “lock” or “unlock” button on your newly programmed key fob.
- Remove the key from the ignition. You should hear a final chime sound.
- Open and close the door once more.
- Wait approximately five seconds. Now, test your key fob by pressing the lock and unlock buttons to see if they function correctly.
Congratulations! If all steps were followed correctly, your Subaru key fob should now be programmed and working seamlessly with your vehicle.
Subaru Key Fob Battery Replacement: Keeping Your Key Fob Powered
Sometimes, key fob issues aren’t due to programming but simply a dead battery. For owners of newer Subaru models with rectangular-shaped key fobs, battery replacement is a straightforward process. Here’s a quick guide:
Battery Replacement for Newer Subaru Key Fobs (Rectangle Shape) – Requires a CR2032 Battery
- Remove the Mechanical Key: On the back of your rectangular key fob, locate a small silver tab. Push this tab to release and pop out the hidden metal mechanical key.
- Pry Open the Fob: In the slot where you removed the mechanical key, insert the tip of the key or a small flathead screwdriver.
- Separate the Casing: Gently twist the key or screwdriver in the gap to carefully pry open the key fob cover. It should separate into two halves.
- Locate the Battery: Inside the opened key fob, you’ll find the battery, often located on the circuit board.
- Battery Removal & Replacement: Carefully remove the old battery. Note the orientation (which side is facing up). Install the new CR2032 battery, ensuring the correct side is facing upwards.
- Reassemble: Carefully snap the two halves of the key fob case back together until they are securely closed. Re-insert the mechanical key.
With a fresh battery, your key fob should be back in action!
