Understanding Your 2009 Subaru Forester Key Fob

Before diving into programming, it's crucial to understand the components of your Subaru's key system. For a 2009 Subaru Forester, your key typically consists of two main parts that may or may not be integrated into a single 'remote head key':

  • The Remote Keyless Entry (RKE) Fob: This is the part that locks, unlocks, and often triggers a panic alarm. It communicates wirelessly with your vehicle's security system.
  • The Transponder Chip: Embedded within the key head (even if it looks like a traditional key) or sometimes in a separate fob, this chip communicates with your car's immobilizer system. Without its correct code, your car will not start, even if you can physically turn the ignition.

It's important to differentiate these, as the programming procedure often differs for each. Many owners often ask: Can I program a new key fob without the original? The answer depends on what you're trying to program.

DIY Programming for 2009 Subaru Forester Remote Keyless Entry (RKE) Fob

Good news for 2009 Subaru Forester owners: the remote keyless entry portion of your key fob can often be programmed at home without specialized tools. This procedure typically applies to adding new remotes or reprogramming existing ones. While success can vary, here’s a common sequence. Remember to have all remotes you wish to program with you, as this process may erase previously programmed fobs.

Step-by-Step DIY Remote Programming:

  1. Preparation: Sit in the driver's seat with all doors closed and unlocked. Have all remotes you want to program handy.
  2. Cycle Ignition: Insert your key into the ignition. Turn the key from 'OFF' to 'ON' (without starting the engine) and then back to 'OFF' for ten seconds. Repeat this sequence approximately 5-10 times. Your goal is to trigger the system to enter programming mode. You may hear a 'chirp' or see lights flash when successful.
  3. Enter Programming Mode: Once the system enters programming mode (indicated by a chirp or flashing lights), you have a short window (usually 45 seconds) to program your remotes.
  4. Program Remotes: Take the first remote. Press and hold any button on the remote for at least one second. Release it. The car should chirp or flash its lights, confirming the remote has been programmed.
  5. Program Additional Remotes: Repeat step 4 for any other remotes you wish to program (e.g., a spare or a new one).
  6. Exit Programming Mode: Once all remotes are programmed, remove the key from the ignition. Open and close the driver's side door. Test all programmed remotes.

Troubleshooting Tips for DIY Remote Programming:

  • No Chirp/Flash: Ensure all doors are closed properly, and the key cycle count is accurate. Try the sequence faster or slower. Dead batteries in the remote itself can also prevent it from sending a signal.
  • Only One Remote Works: You must program all remotes (old and new) in a single session. If you only program one, the others may be erased.
  • Ignition Issues: Ensure your ignition switch is fully rotating to 'OFF' and 'ON' without getting stuck.

When Professional Key Fob Programming is Required

While DIY remote programming is feasible for the RKE function, the transponder chip programming for your 2009 Subaru Forester is a different story. The engine immobilizer system requires specialized diagnostic equipment to sync a new transponder chip with your vehicle's computer. This is a critical security feature, and only a certified professional, like DML Locksmith Services, or a dealership, has the tools and expertise to perform this safely and accurately.

Frequently Asked Questions (FAQ)

Q: Can I use a used key fob for my 2009 Subaru Forester?

A: For the remote keyless entry (RKE) portion, sometimes. If the used fob matches the correct part number and frequency, it can often be reprogrammed. However, transponder chips in used keys are typically 'locked' to their original vehicle and usually cannot be reprogrammed to a new vehicle. It's almost always recommended to use a new, blank transponder chip for engine start functionality.

Q: How long does 2009 Subaru Forester key fob programming take?

A: DIY programming for the RKE can take as little as 5-10 minutes. For professional programming of a transponder chip or a new remote, our highly qualified service technicians can typically complete the process within 15-30 minutes once on-site and connected to your vehicle's system.

Q: What if my 2009 Subaru Forester key fob battery dies?

A: A dead battery will prevent the remote keyless entry functions (lock, unlock, panic) from working, but your transponder chip, if separate, may still allow you to start the car by physically inserting the key into the ignition. Replacing the battery is a simple DIY task, often requiring just a small screwdriver and a new CR2032 or similar coin-cell battery. However, if the battery is replaced and the remote still doesn't work, reprogramming may be necessary.
