2019 Subaru Outback Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2019 Subaru Outback does not support DIY on-board programming for its smart key fob. This means you cannot program a new key fob yourself using a sequence of button presses or key turns.

The 2019 Subaru Outback utilizes an advanced immobilizer system that requires specialized diagnostic equipment to program new key fobs. This process involves linking the new fob to the vehicle's immobilizer control unit.

Battery replacement

1. Locate the small release button or switch on the side of the key fob. Press or slide it to release the emergency key blade. Remove the emergency key blade.
2. With the emergency key blade removed, you'll see a small slot or notch. Use a small flat-head screwdriver or a coin to gently pry open the two halves of the key fob casing.
3. Carefully separate the two halves. You'll see the circuit board and the CR2032 coin cell battery.
4. Note the orientation of the old battery (usually positive side up). Use a small, non-metallic tool to gently pop out the old CR2032 battery.
5. Insert the new CR2032 battery with the positive (+) side facing the same direction as the old one.
6. Carefully align the two halves of the key fob casing and snap them back together until they are securely closed.
7. Reinsert the emergency key blade into the key fob until it clicks into place.

Where to buy a replacement fob

• Subaru Dealership: This is often the most expensive option, but it guarantees an OEM part and professional programming. They will typically cut the emergency key blade and program the fob for you. Ballpark Price: $300 - $500+ (includes fob, cutting, and programming).
• Automotive Locksmith: A qualified automotive locksmith can provide and program aftermarket or OEM-equivalent key fobs at a more competitive price than the dealership. They also have the necessary diagnostic tools and key cutting equipment. Ballpark Price: $200 - $400 (includes fob, cutting, and programming).
• Online Retailers (e.g., Amazon, eBay): You can often find replacement key fobs (OEM used or aftermarket new) for a lower price online. However, remember that these will still need to be programmed and the emergency key blade cut by a professional locksmith or dealership. Ensure the FCC ID and part number match your original fob for compatibility. Ballpark Price: $50 - $150 (for the fob itself, programming and cutting extra).

If on-board programming isn't supported

Since the 2019 Subaru Outback requires specialized equipment for key fob programming, you'll need to factor in the cost of a professional service. The vehicle uses an immobilizer transponder system where the key fob communicates wirelessly with the vehicle's computer to allow the engine to start. This system is a critical anti-theft feature, and programming a new fob involves updating the vehicle's computer to recognize the new key's unique code.

Cost Expectations: As mentioned above, expect to pay anywhere from $200 to $500+ depending on whether you go with an independent automotive locksmith or a Subaru dealership. This cost typically covers the new key fob (or the programming of one you provide), the cutting of the emergency key blade, and the programming fee.
