Easy DIY Guide: How to Program Your 2010 Subaru Key Fob in Minutes

As a Subaru car owner, you understand that a key fob is an essential component for unlocking your Subaru car’s doors, trunk, and starting the engine. If your key fob is lost, damaged, or not functioning correctly, you might be faced with an expensive replacement at your dealership. However, you can save time and money by programming a new key fob yourself. In this DIY guide, we will show you how to program your 2010 Subaru Key Fob easily in minutes.

Importance of Programming Your Subaru Key Fob

Programming your Subaru key fob is more than unlocking your car’s doors; it is critical in ensuring the safety of your vehicle’s security system. By programming your key fob, you are syncing the device with your car’s computer system to ensure only the programmed key fob can start the engine. Without programming your key fob to your car’s computer, someone could start the engine with an unprogrammed key, putting your vehicle at risk.

Materials Required for Programming

To program your 2010 Subaru Key Fob, you need to have both the key fob and your car’s owner manual. Your owner’s manual is essential as it contains the programming instructions specific to your car’s model and year.

How to Program the Subaru Key Fob

  1. Open the driver’s door and manually lock it from the inside with the physical key.

  2. Insert your car’s key into the ignition and turn it to the "ON" position. Ensure the door is still closed.

  3. After five seconds, turn back the key to the "OFF" position. Repeat this step three more times while waiting five seconds in between each iteration.

  4. After the fourth time, turn the key back to the "ON" position. The doors should lock, unlock, and then lock again. This proves that your car is now in the key fob programming mode.

  5. Press and hold the "LOCK" and "UNLOCK" buttons on the key fob together. After fifteen seconds, the car’s horn will beep once, indicating the key fob is now programmed.

  6. Release the buttons and then turn off the car’s ignition. Test the key fob for its functionality.
