2016 Subaru Outback Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2016 Subaru Outback, especially with its smart key/proximity key system, does not support DIY on-board programming for additional key fobs. This means you cannot simply perform a series of steps with your existing key to program a new one. The vehicle's immobilizer system and the advanced features of the smart key require specialized diagnostic equipment to add new fobs.

To program a new key fob for your 2016 Subaru Outback, you will need to visit a Subaru dealership or an automotive locksmith who has the necessary scan tools and software. These tools communicate directly with your vehicle's Body Integrated Unit (BIU) or Smart Entrance Control Module to register new key fobs and ensure proper synchronization with the immobilizer system.

Battery replacement

Replacing the battery in your 2016 Subaru Outback key fob is a straightforward process:

1. Locate the release button: On the back or side of your key fob, you'll find a small button or switch. Press or slide this to release the emergency key blade. Pull the emergency key out.
2. Open the casing: With the emergency key removed, you should see a small slot or indentation where the key blade was. Use a small flat-head screwdriver or a coin to carefully pry open the two halves of the key fob casing. Work your way around the seam until the casing separates.
3. Remove the old battery: Once open, you'll see the circuit board and the CR2032 coin cell battery. Note the orientation of the battery (which side is facing up). Gently pry out the old battery.
4. Insert the new battery: Place the new CR2032 battery into the compartment, ensuring it's oriented correctly (the positive side, usually marked with a '+' symbol, should match the orientation of the old battery).
5. Reassemble the fob: Carefully snap the two halves of the key fob casing back together until they are securely closed. Reinsert the emergency key blade.
6. Test the fob: Test all the buttons (lock, unlock, trunk, panic) to ensure they are working correctly.

Where to buy a replacement fob

When it comes to purchasing a replacement key fob for your 2016 Subaru Outback, you have a few options, each with its pros and cons:

• Subaru Dealership:

  • Pros: Guaranteed to be an OEM part, often comes with programming included in the price, and technicians are highly familiar with Subaru systems.
  • Cons: Most expensive option. Expect to pay anywhere from $250 to $400 or more for the fob and programming.

• Automotive Locksmith:

  • Pros: Can often provide OEM or high-quality aftermarket fobs, typically at a lower cost than the dealership. They have the specialized programming equipment and can often come to your location (mobile service). Pricing for a fob and programming can range from $150 to $300.
  • Cons: Quality of aftermarket fobs can vary, so ensure the locksmith uses reputable brands.

• Online Retailers (e.g., Amazon, eBay, specialty key sites):

  • Pros: Cheapest option for the fob itself. You can find OEM or aftermarket fobs for as low as $50-$100.
  • Cons: You're only buying the physical fob; you'll still need to pay for cutting the key blade (if applicable) and programming separately. The quality of aftermarket fobs can be inconsistent, and verifying compatibility can be tricky. Be wary of fobs that claim to be "self-programmable" for a 2016 Outback, as this is generally not accurate for this model.

If on-board programming isn't supported

As established, on-board programming is not an option for your 2016 Subaru Outback's smart key. This means you will need professional assistance. When considering costs, remember that you're paying for both the physical key fob and the programming service.

• Cost Expectations: As mentioned above, expect to pay between $150 and $400+ for a new fob and programming from a locksmith or dealership. This cost covers the specialized diagnostic tools, technician's time, and the key fob itself.

• Immobilizer Transponder: The 2016 Subaru Outback uses an immobilizer system that relies on a transponder chip embedded within the key fob. This chip communicates with the vehicle's immobilizer to allow the engine to start. When a new key fob is programmed, the immobilizer system learns and registers the unique code of the new transponder. Without proper programming, even if the remote functions work (lock/unlock), the vehicle will not start due to the immobilizer preventing it. This is a critical security feature and why specialized equipment is required for programming.
