If you’re a proud owner of a Subaru Forester, you know that its functionality relies heavily on our modern conveniences, including the key fob. While these little gadgets make our lives easier by allowing for keyless entry and ignition, they can also lead to frustration when they stop working. If you’ve recently encountered problems with your Subaru Forester key fob, fear not! This comprehensive guide will walk you through the troubleshooting process, possible causes, and solutions to get your key fob back in action.
Understanding Your Subaru Forester Key Fob
Subaru has equipped its vehicles, including the Forester, with key fobs that not only unlock the doors but can also start the engine with just a push of a button. The key fob functions through a series of signals transmitted via infrared or radio waves to the vehicle’s onboard computer system. However, like all electronic devices, they can sometimes malfunction.
Common Symptoms of a Key Fob Issue
Before diving into troubleshooting steps, it’s essential to identify the symptoms indicating that your key fob might be malfunctioning. Some common issues include:
- Inability to unlock or lock the doors remotely.
- The engine does not start when the fob is inside the vehicle.
Recognizing these symptoms early can help you take proactive measures to resolve the issue.
Possible Causes of a Non-Working Key Fob
Understanding the reasons your Subaru Forester key fob may not be working is crucial to resolving the issue effectively. Here are some potential causes:
Dead Key Fob Battery
One of the most common reasons for key fob failure is a dead battery. Key fob batteries can last anywhere from a couple of years to several years, depending on usage. A battery that is weak or dead typically produces signs such as a delayed response or a complete lack of functionality.
How to Replace Your Key Fob Battery
Replacing your Subaru Forester key fob battery is a straightforward process:
- Obtain a replacement battery suitable for your fob (usually CR2032).
- Use a flathead screwdriver to carefully pry open the fob case.
- Remove the old battery and install the new one, ensuring the polarity is correct.
- Close the fob and test it to see if the issue is resolved.
Signal Interference
Another potential cause for your key fob’s failure could be interference from various electronic devices or other key fobs. This interference can prevent the signals from transmitting effectively, resulting in your key fob not working properly.
Identifying Signal Interference
To test for signal interference, try using your key fob in a different location away from electronic devices, garages, or stores. If the fob works in a different place, consider moving away from potential sources of interference in the future.
Faulty Key Fob or Vehicle Receiver
If the battery replacement and signal interference don’t resolve the issue, the problem could be with either the key fob itself or the vehicle’s receiver. A damaged key fob or a malfunctioning receiver may need professional repair or replacement.
Diagnosing Key Fob and Receiver Issues
- Testing with a Spare Key Fob: If you have a spare key fob, try using it. If it works without any issues, then your original fob may be faulty.
- Consulting Your Subaru Forester Manual: Refer to your user manual for any additional troubleshooting tips.
Steps to Troubleshoot Your Subaru Forester Key Fob
Sometimes, all your key fob needs is a little troubleshooting. Here is a step-by-step guide to address your issues effectively:
Step 1: Replace the Key Fob Battery
As explained earlier, a dead battery is a common reason for malfunctioning key fobs. Replacing it is usually a simple and effective first step.
Step 2: Re-sync Your Key Fob
If the key fob remains unresponsive after changing the battery, it might need to be re-synced with your vehicle. Here’s how to do this:
- Start with the key fob inside your Subaru Forester.
- Turn the ignition to the “ON” position without starting the engine.
- Press and hold the “LOCK” button for several seconds.
- Turn off the ignition and then turn it back on to check if it’s been successfully resynchronized.
Step 3: Inspect the Key Fob for Physical Damage
Check your key fob for any physical damage—cracks, broken buttons, or anything else that seems out of the ordinary. If the fob is damaged:
- You might need to consult a professional for repair.
- In some cases, it may be more cost-effective to purchase a new key fob.
Step 4: Consult Your Subaru Dealership
If none of the previous steps have resolved your key fob issues, it’s time to consult your local Subaru dealership. They have the right diagnostic tools and expertise to pinpoint and solve the issue effectively.
Cost Implications of Key Fob Issues
When facing key fob issues, it’s essential to consider the financial implications. Costs can vary depending on whether you need a battery replacement, a repair, or a complete key fob replacement.
Battery Replacement Costs
Replacing the battery yourself usually costs around $5 to $10 for the battery itself. However, if you prefer professional assistance, you may incur labor costs ranging from $10 to $50.
Key Fob Repair/Replacement Costs
- Repair Costs: If the key fob is repairable, costs can range from $50 to $100, depending on the extent of the damage.
- Replacement Costs: If you need a new key fob, prices can vary widely, anywhere from $150 to $400, depending on the dealership or service provider.
Preventative Measures to Avoid Future Key Fob Issues
To maintain your key fob in good working order and prolong its life, consider the following preventative measures:
Regular Battery Check
Make it a habit to check your key fob battery when you switch your clocks for daylight saving time or during routine car maintenance intervals.
Avoid Exposing Your Key Fob to Extreme Conditions
Excessive heat or moisture may damage the internal components of the key fob. Be cautious when leaving your fob in extreme conditions or exposing it to liquid.
Conclusion
Experiencing issues with your Subaru Forester key fob can be frustrating, but understanding the underlying causes and applying the troubleshooting methods outlined in this guide can help resolve the problem efficiently. Whether it’s a simple battery replacement or a potential failure with the fob itself, taking proactive steps can save you time and money in the long run.
With the right care and knowledge, your Subaru Forester key fob can continue to serve you reliably for years to come. Keep this guide handy, and you’ll be well-prepared to address any key fob issues when they arise!
What should I do if my Subaru Forester key fob is not working?
If your Subaru Forester key fob is not responding, the first step is to check the battery. A common issue with key fobs is that the battery may be dead or low on charge. To check this, try replacing the battery with a new one. Most Subaru key fobs use a CR2032 battery, and you can find instructions for how to open your key fob and replace the battery in your owner’s manual.
If replacing the battery doesn’t solve the problem, try reprogramming the key fob. Sometimes, the fob can lose synchronization with the vehicle. Refer to your owner’s manual for specific instructions on how to reprogram the key fob for your Subaru Forester model year, as the steps may vary.
How can I tell if the battery in my key fob needs to be replaced?
There are several indicators that your key fob battery may be running low. One common sign is a reduced range when trying to unlock or start your Subaru Forester. If you find yourself having to stand closer to the vehicle or pressing the button multiple times, it’s likely a sign that the battery is weakening. Additionally, if you notice that the LED light on the key fob is dim or flickering, this also suggests that the battery might need replacing.
Another way to confirm battery issues is to use a spare key fob, if you have one. If the spare fob works without issues, it’s a good indication that the original key fob’s battery is failing. Replacing the battery in the key fob should resolve the issue, and you can do this easily with a new CR2032 battery.
What should I do if my key fob is damaged?
If your key fob is physically damaged, such as having a cracked or broken casing, it may no longer function properly, even if the internal components are intact. In this case, you will want to assess the extent of the damage. Minor cosmetic damages may not affect the performance, but if the internal circuitry is broken, you will need to replace the fob. Look for visible signs like broken buttons or detached parts.
To replace a damaged key fob, you can visit your local Subaru dealership or order a new one online. If you choose to order one online, ensure it is compatible with your Subaru Forester model. Once you have a new fob, you will need to have it programmed to work with your vehicle, which can often be done at the dealership but may also be possible at some auto locksmiths.
Can I program my Subaru Forester key fob myself?
Yes, in many cases, you can program your Subaru Forester key fob yourself using the vehicle’s built-in programming mode. This typically involves a sequence such as turning the ignition on and off a certain number of times and pressing buttons on the key fob. The specific steps may vary depending on the model year of your Forester, so it is crucial to consult your owner’s manual for detailed instructions.
Keep in mind that some models may require a special tool or need to be programmed by a professional, particularly if you have lost all keys. If you are uncomfortable with self-programming or if it doesn’t work after several attempts, it might be best to seek help from a Subaru dealer or an automotive locksmith.
Why does my Subaru Forester key fob only work intermittently?
If your key fob only works intermittently, it may be caused by several factors. The most common reason is a dying battery, which may still provide sporadic power but isn’t consistent enough for full functionality. To rule out this issue, replace the battery and see if the intermittent problem persists. If it doesn’t improve, the issue might lie within the fob itself.
Another possible reason could be interference from other electronic devices. Key fobs can sometimes be affected by devices emitting radio frequencies, such as wireless speakers or even other key fobs. Try to test the fob in different conditions or locations to see if the problem continues. If it persists, the fob may be damaged or malfunctioning internally, requiring replacement or repair.
Is it possible to unlock my Subaru Forester without the key fob?
Yes, you can unlock your Subaru Forester without the key fob, although it may require an alternative method. If you have a physical key that fits in the door lock, you can unlock the vehicle manually. Most Subaru key fobs contain a hidden mechanical key that can be extracted from the fob itself. This key allows you to unlock the driver’s side door and gain access to the vehicle.
If you do not have access to the physical key and the key fob is not working, you may need to contact a locksmith or your local Subaru dealership for assistance. They can help unlock your vehicle and, if needed, provide you with a replacement key fob or mechanical key that works with your specific model.
What to do if the key fob is lost?
If your Subaru Forester key fob is lost, the first step is to retrace your steps to see if you can locate it. Check common spots like your home, car, or places you may have visited recently. Use a flashlight to look in areas that might be hard to reach. If you’re unable to find it, you will need to get a replacement key fob.
To obtain a replacement, you can visit your local Subaru dealership, where they can provide you with a new fob and help you program it to your vehicle. Be prepared to provide your vehicle identification number (VIN) and proof of ownership. Alternatively, you can also reach out to an automotive locksmith, as they may offer more affordable options for replacing and programming a new key fob.
