Is your 2018 Subaru Crosstrek key fob acting up? Before you schedule a costly trip to the dealership, consider this: a dead key fob battery could be the culprit. Thankfully, replacing the battery is a simple DIY task that can save you time and money. This comprehensive guide will walk you through everything you need to know about your Subaru key fob battery, from identifying the signs of a dying battery to programming a new one.
Recognizing a Dying Key Fob Battery
Identifying a failing key fob battery early can prevent inconvenient lockouts. Here are some telltale signs:
- Decreased Range: Does your car only respond to the key fob at close range? This is often the first indication of a weakening battery.
- Intermittent Functioning: Does your key fob work sporadically? This inconsistency suggests the battery is nearing its end.
- Dim Indicator Light: The key fob’s indicator light should flash brightly when you press a button. A dim or non-responsive light signals a low battery.
What Battery Does My 2018 Subaru Crosstrek Key Fob Use?
Your 2018 Subaru Crosstrek key fob uses a CR2032 battery, a common type found at most convenience stores, auto parts shops, and online retailers.
DIY Subaru Key Fob Battery Replacement
Replacing the battery in your 2018 Subaru Crosstrek key fob is straightforward:
- Locate the Release Button: On the back of the key fob, find the small release button or notch.
- Separate the Key Fob: Press the release button and gently separate the two halves of the key fob. You may need to use a flathead screwdriver or a coin to pry it open.
- Remove the Old Battery: Inside the fob, you’ll find the CR2032 battery. Carefully remove it, noting the battery’s positive (+) and negative (-) orientation for the new battery.
- Install the New Battery: Insert the new CR2032 battery, ensuring the positive (+) side faces up, matching the old battery’s placement.
- Reassemble the Key Fob: Align the two halves of the key fob and press them together until they snap securely back into place.
Programming Your Subaru Key Fob After Battery Replacement
For most 2018 Subaru Crosstrek models, programming the key fob after a battery replacement is unnecessary. The system should automatically recognize and sync with the new battery.
Important Note: If your key fob still doesn’t function properly after replacing the battery, there might be an underlying issue with the fob itself, or it may require specific programming steps. In such cases, consulting your owner’s manual or contacting a qualified automotive locksmith or dealership is recommended.

Extending the Life of Your Subaru Key Fob Battery
Follow these tips to maximize your key fob battery’s lifespan:
- Avoid Extreme Temperatures: Prolonged exposure to heat or cold can drain battery life. Store your key fob in a cool, dry place when not in use.
- Minimize Button Presses: While tempting, repeatedly pressing the buttons when the car is out of range can deplete battery power faster.
- Keep it Dry: Moisture is detrimental to electronic components. Avoid getting your key fob wet and wipe it dry immediately if it does.
Key Fob Programming: When You Need a Professional
While replacing the battery is a simple DIY task, there are instances where professional programming is essential. This includes:
- Adding a New Key Fob: If you lose a key fob or want a spare, a qualified locksmith or dealership can program a new one to your Subaru.
- Key Fob Malfunction: If a key fob stops working entirely or exhibits erratic behavior beyond a battery issue, it may require reprogramming or replacement.
Key Fob Troubleshooting Tips
If your Subaru key fob is experiencing issues, try these troubleshooting steps:
- Check the Battery: As mentioned earlier, a low or dead battery is the most common culprit. Replace the battery and check if the issue persists.
- Check for Signal Interference: Strong radio waves or electronic devices near your car can interfere with the key fob signal. Move away from such sources and try again.
- Try the Spare Key Fob: If you have a spare key fob, test it to see if the issue is with the fob itself or the car’s system.
