2022 Subaru Crosstrek Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

The 2022 Subaru Crosstrek does not support DIY on-board programming for its key fobs. The sophisticated security system requires specialized diagnostic tools to program new key fobs to the vehicle's immobilizer system. This procedure typically involves linking the new fob's unique code to the vehicle's computer. Therefore, you will need to visit a Subaru dealer or an automotive locksmith for programming.

Why no DIY programming?

Modern Subaru vehicles like the 2022 Crosstrek utilize an advanced immobilizer system that communicates with a transponder chip embedded within the key fob. This system is designed to prevent theft by ensuring that only properly programmed keys can start the engine. The programming process involves accessing the vehicle's onboard computer (ECU) and often requires entering security codes and performing specific software routines that are only available through specialized diagnostic equipment.

Battery replacement

Replacing the CR2032 battery in your 2022 Subaru Crosstrek key fob is a straightforward process:

1. Remove the emergency key: Press the small release button on the side of the fob and pull out the metal emergency key.
2. Separate the fob casing: With the emergency key removed, you'll see a small notch on the side of the fob. Use a small flathead screwdriver or a coin to carefully pry open the two halves of the key fob casing.
3. Replace the battery: Locate the CR2032 coin cell battery. Note its orientation (positive side up) and gently pry it out. Insert the new CR2032 battery with the positive (+) side facing up.
4. Reassemble the fob: Carefully snap the two halves of the key fob casing back together until it's secure. Reinsert the emergency key.

Where to buy a replacement fob

When you need a new key fob for your 2022 Subaru Crosstrek, you have a few options, each with its pros and cons:

• Subaru Dealership:

  • Pros: Guaranteed genuine OEM part, expert programming, and support. They have all the necessary diagnostic tools.
  • Cons: Most expensive option. Expect to pay anywhere from $250 to $400 or more for the key fob and programming.

• Automotive Locksmith:

  • Pros: Often more affordable than a dealership, especially mobile locksmiths who come to you. They use specialized tools to cut and program keys. Can often program both OEM and good quality aftermarket fobs.
  • Cons: Quality of aftermarket fobs can vary. Ensure the locksmith is reputable and experienced with Subaru systems.
  • Cost: Typically $180 to $300, including the fob and programming.

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

  • Pros: Potentially the cheapest way to buy the physical fob.
  • Cons: You're buying just the hardware; you'll still need to pay a locksmith or dealer for cutting the emergency key and programming. Risk of buying a non-compatible or low-quality aftermarket fob. Many sellers don't offer return policies if the fob can't be programmed.
  • Cost: Fobs alone can range from $50 to $150, but remember to factor in programming and cutting costs.

If on-board programming isn't supported

As established, the 2022 Subaru Crosstrek requires professional programming. This is due to its advanced immobilizer system. Each key fob contains a unique transponder chip that communicates with the vehicle's immobilizer. This system prevents the car from starting if an unprogrammed key is used, enhancing security.

When getting a new key fob, ensure that the emergency key blade is cut to match your vehicle's ignition and door locks. This is typically done by code, using your VIN, or by duplicating an existing key.

Cost Expectations:

• Given the need for specialized equipment, expect to pay for both the key fob itself and the labor involved in programming and cutting the emergency key. The total cost, as mentioned above, can range from approximately $180 to over $400, depending on where you go and whether you provide the blank fob yourself.
