This small yet crucial gadget serves as the gateway to the convenience and advanced security that Subaru vehicles offer. Whether it’s the inconvenience of not having access to your car or the headache of troubleshooting the issue, understanding why your Subaru key fob isn’t working is essential for smooth journeys ahead. In this comprehensive guide, we will explore the common reasons for key fob malfunctions, step-by-step troubleshooting tips, and some recommendations for future care.
Common Reasons Your Subaru Key Fob Isn’t Working
Understanding the root causes of key fob malfunctions can save you time and frustration. Key fob issues can stem from various problems, and pinpointing the cause can help you find the right solution.
1. Dead or Weak Battery
One of the most frequent reasons your Subaru key fob may stop working is a dead or weak battery. Most key fobs operate on small coin batteries, which can wear out over time due to regular use.
Symptoms of a Weak Battery
- Unresponsiveness: Pressing the buttons doesn’t yield any results.
- Intermittent Functionality: Sometimes the key fob works, but other times it does not.
- Limited Range: You have to be closer to the vehicle for it to respond.
2. Signal Interference
Yet another factor that can affect your Subaru key fob is signal interference. Various electronic devices, metal objects, or even other vehicles using similar frequencies can disrupt communication between the fob and your car.
Potential Sources of Interference
- Cell Phones: Proximity to your mobile device while trying to unlock or start your car.
- Other Key Fobs: Nearby vehicles may cause interference when their key fobs are activated.
- Electronic Equipment: Devices that emit radio frequencies, such as security systems, can cause disruptions.
3. Faulty Key Fob
In some cases, the key fob may be malfunctioning due to physical damage or wear and tear. Water damage, falling, or infiltration of dirt and debris can hinder its functionality.
Signs of a Faulty Key Fob
- Visible Damage: Cracks or broken components.
- Lack of Response: Despite a good battery, the fob doesn’t engage.
- Button Resistance: Sticking or jammed buttons may indicate physical issues.
4. Vehicle Reception Problems
Sometimes, the problem isn’t with your key fob but with the vehicle itself. A malfunctioning receiver in the car can cause issues where the fob signals are not being acknowledged properly.
Indicators of Reception Problems
- The car doesn’t respond to the key fob are several attempts.
- The fob works with some functions but fails for others (such as starting the engine).
Troubleshooting Your Subaru Key Fob
Once you’ve identified potential causes of your Subaru’s key fob malfunction, it’s time to take action. Here’s a step-by-step guide to troubleshooting the issue.
Step 1: Check the Battery
The first and most straightforward step is to check the key fob battery. Here’s how to do it:
- Open the Key Fob: Usually, this involves pressing a small tab or unscrewing a cover.
- Inspect the Battery: Check for any signs of corrosion or damage. Remove it if needed and test it with a multimeter, or simply replace it with a new battery.
Step 2: Test for Signal Interference
If the battery seems fine, eliminate potential sources of interference:
- Move Away from Other Electronics: Try activating the key fob away from other electronic devices.
- Check Your Location: If you’re in a densely populated area, look for other vehicles that might be using similar frequencies.
Step 3: Examine the Key Fob for Damage
After ruling out the above steps, take close note of the key fob condition:
- Look for Physical Ts: Check for cracks or damage to the housing.
- Inspect the Buttons: Ensure the buttons aren’t jammed or sticking. If water damage is suspected, allow it to dry thoroughly – but avoid using heat.
Step 4: Verify Vehicle Receiver Functionality
If all else fails, it may be time to check the vehicle’s receiver:
- Test with a Spare Key Fob: If you have another functioning key fob, try using it. If it works, your original key fob might be the issue.
- Diagnostics by a Professional: If you suspect the vehicle’s receiver, take the car to a certified Subaru technician for diagnostic testing.
When to Seek Professional Help
If you’ve attempted all the troubleshooting steps and your Subaru key fob still isn’t working, it may be time to consult a professional. There could be underlying issues within the vehicle’s security and ignition mechanisms. Here are some instances when seeking expert help is advisable:
- If your key fob is damaged beyond repair.
- If all signs point to receiver failure, requiring complex diagnostics or repairs.
How to Maintain Your Subaru Key Fob for Longevity
To prevent key fob issues in the future, maintenance is key. Here are some proactive tips:
1. Keep It Dry and Clean
Avoid exposing your key fob to water and clean it regularly. If it does get wet, ensure it is dried thoroughly. Use a soft cloth to wipe down the exterior to keep dirt and debris at bay.
2. Replace the Battery Regularly
Many experts recommend replacing the battery every 2-3 years, regardless of usage. Keep a spare battery at home for quick replacements.
3. Avoid Excessive Handling
Try not to drop or mishandle the key fob. It’s a delicate instrument, and rough usage can lead to issues.
Understanding Your Subaru Key Fob and Its Features
Subaru key fobs come equipped with various features that enhance your overall driving experience. Here are a couple of common functionalities:

Replacement Options for Non-Working Key Fobs
If your key fob is beyond repair, there are a few options to replace it. Replacement can vary in cost, so consider what suits you best.
1. Dealer Replacement
Although this option might be pricier, it ensures that you receive an OEM (original equipment manufacturer) part tailored for your specific Subaru model.
2. Aftermarket Fobs
Numerous retailers offer aftermarket key fob replacements. However, be cautious, as compatibility and quality can vary significantly. Always verify that the replacement key fob you purchase is compatible with your Subaru model.

What are common reasons for a Subaru key fob not working?
There are several common reasons that may cause your Subaru key fob to stop functioning properly. One of the most frequent issues is a dead battery, which can prevent the key fob from communicating with the vehicle’s receiver. Over time, the battery in the key fob will drain, especially if the fob is used frequently or if it is older. It’s crucial to examine the battery first, as replacing it is usually a simple and straightforward fix.
Another reason could be interference from other electronic devices or a malfunctioning receiver in the vehicle. External factors such as nearby electronic gadgets, environmental elements, or even a broken key fob can disrupt the communication between the key fob and the car. If you’ve recently been using the fob in an area with heavy electronic interference, this might also be a contributing factor.
How do I know if the battery in my key fob is dead?
You can typically tell if the battery in your Subaru key fob is dead if the fob is unresponsive when you try to unlock or start your vehicle. Signs may include the key fob not working at all or only functioning intermittently. If you have a spare key fob that functions correctly, you can also use it to rule out other potential issues with the vehicle itself.
To confirm that the battery is indeed dead, you can open the fob and inspect the battery visually. If you see signs of corrosion, leakage, or if the battery appears to be old, this is a strong indication that it should be replaced. In most cases, replacing the battery will restore functionality, and you can follow the manufacturer’s instructions for doing so.
Can I reprogram my Subaru key fob myself?
In many cases, you can reprogram your Subaru key fob yourself, but the steps can vary depending on the model and year of your vehicle. Generally, you will need to follow a specific sequence involving turning the ignition on and off and pressing the buttons on the fob in a designated order. It’s important to consult your owner’s manual or manufacturer’s website for detailed instructions specific to your model.
However, if the programming process feels too complicated or if you find that the key fob is still not working after attempting to reprogram it, reaching out to a professional locksmith or Subaru dealership might be the best option. They have the necessary tools and expertise to diagnose and fix any issues with your key fob effectively.
Why is my key fob working intermittently?
An intermittent key fob can be frustrating, often caused by a low battery, which may not be delivering consistent power. Sometimes the battery contacts can become dirty or corroded, which prevents the fob from communicating with the vehicle reliably. Regular maintenance of the key fob can help prevent such issues, including cleaning the contacts to ensure a strong connection.
Another possible cause of intermittent functionality could be electronic interference. If you notice that the fob works in some locations but not in others, it’s likely caused by temporary interference from other devices or electrical systems. In this case, you might want to test the fob in a variety of locations to determine if interference is indeed the culprit.
What should I do if my key fob is damaged?
If you suspect that your key fob is damaged, it’s essential to begin with a careful inspection. Look for visible signs of wear, such as cracks, broken buttons, or signs of liquid damage. If you notice anything unusual, the fob may need to be repaired or replaced. Depending on the extent of the damage, a replacement fob might be the easiest solution.
In some cases, a damaged key fob can be repaired, but this typically requires professional assistance. A locksmith or dealership can assess the damage and provide options tailored to your situation. Keep in mind that some repairs may cost nearly as much as a new fob, so it’s helpful to compare both options before making a decision.
Is there a way to reset my Subaru key fob?
Resetting a Subaru key fob can sometimes resolve communication issues between the fob and the vehicle. The exact process depends on the model and year of your Subaru, but it generally involves steps similar to reprogramming. Commonly, this includes turning the ignition on and off several times and then pressing specific buttons on the fob.
If the reset process does not restore functionality, there might be underlying issues, such as damage to the fob or problems with the car’s receiver. In such cases, it’s advisable to consult with a professional locksmith or contact a Subaru dealership who can offer expert assistance and ensure that your key fob is operating correctly.
What are the costs associated with replacing a Subaru key fob?
The cost of replacing a Subaru key fob can vary depending on several factors, including the model of your vehicle and the location of the service provider. On average, you can expect to pay anywhere from $50 to $200 for a replacement key fob. This includes the cost of the fob itself along with any necessary programming or installation fees.
Additionally, if you are visiting a dealership, prices may be on the higher end of that spectrum. It’s often possible to find more cost-effective options through locksmiths or online retailers, but ensure that any fob purchased can be properly programmed to your vehicle. It’s advisable to call around to different service providers to compare prices and get the best deal.
