Subaru vehicles are renowned for their reliability, performance, and cutting-edge technology. However, like any automotive feature, the remote key fob can experience issues from time to time. If you find yourself in a situation where your Subaru remote key is not working, it can be both frustrating and inconvenient. In this comprehensive guide, we will explore the common reasons why your Subaru remote key may not be functioning properly, possible solutions, and tips for preventing future issues.
Understanding the Subaru Remote Key System
To diagnose the problem accurately, it’s essential to understand how a Subaru remote key fob operates. The remote key fob is designed to provide convenient access to your vehicle, allowing you to lock and unlock doors, activate the alarm, and even start the engine from a distance.
This technology relies on a combination of radio frequency signals and battery power, making it integral to your vehicle’s security and accessibility.
Common Reasons Your Subaru Remote Key Might Not Work
When faced with a malfunctioning remote key fob, there are several common reasons why this might be happening. Understanding these can help you troubleshoot the issue effectively.
1. Dead Battery
The most frequent reason for a non-responsive remote key is a dead or weak battery. Key fob batteries typically last several years, but their lifespan can be influenced by factors such as usage frequency and environmental conditions.
Signs of a Dead Battery
- Inconsistent or weak response when pressing buttons.
- Indicator lights on the fob don’t illuminate.
- The remote works intermittently.
2. Signal Interference
Another potential issue could be signal interference. Other electronic devices, including smartphones, radio towers, or even nearby vehicles, can disrupt the radio frequency signals emitted by your key fob.
Checking for Signal Interference
To check for interference, try using the remote key while standing in different locations, away from buildings or other electronic devices. If the remote works in an alternate location, the problem is likely interference.
3. Faulty Key Fob
Over time, wear and tear can take a toll on your key fob. Physical damage, loose buttons, or internal malfunctions can cause complete failure or unreliable performance.
Signs of a Faulty Key Fob
- Visible cracks or damage on the device.
- Buttons that feel stuck or do not respond.
- The need for multiple presses to function.
4. Programmed Key Issues
In some cases, the key fob may lose its programming, especially if you’ve recently changed your vehicle’s battery or worked on the electrical systems.
Symptoms of a Programmed Key Issue
- The key fob fails to unlock or lock the doors after a new battery installation.
- You receive no response when attempting to start the engine, indicating that the car does not recognize the fob.
Troubleshooting Steps: How to Fix Your Subaru Remote Key
If your Subaru remote key is not working, there are several steps you can take to diagnose and potentially resolve the issue.
Step 1: Replace the Battery
If you suspect the battery is dead, replacing it is the easiest and most straightforward first step. Follow these simple instructions:
- Open the Key Fob: Use a flathead screwdriver to gently pry open the fob case.
- Remove the Old Battery: Take out the old battery carefully.
- Insert the New Battery: Ensure the new battery is installed in the correct orientation.
- Reassemble the Fob: Snap the key fob back together securely.
Step 2: Test for Signal Interference
If replacing the battery doesn’t resolve the problem, check for signal interference. Stand away from electronic devices and attempt to use the remote. If it works in a different location, you’ve identified interference.
Step 3: Inspect the Key Fob for Damage
Check your key fob for any visible damage that could affect its performance. If you notice cracks or loose buttons, it might be time for a replacement.
Step 4: Reprogram Your Key Fob
If all else fails, reprogramming the key fob may restore its functionality. Follow these steps based on your Subaru model:
- Inside the Car: Sit inside the car with all doors closed.
- Turn the Ignition: Insert the key into the ignition and turn it to the “On” position (do not start the engine).
- Press the Lock Button: Press and hold the “Lock” button on the remote for about two seconds.
- Turn the Key Off: Turn the key back to the “Off” position.
- Test the Key Fob: Try using the remote to lock and unlock the doors.
Note: The exact procedure may vary depending on your Subaru model, so refer to your owner’s manual for specific instructions.
When to Seek Professional Assistance
If your attempts to troubleshoot still leave your Subaru remote key unresponsive, it may be time to consult a professional. There are specific circumstances where expert assistance is necessary.
1. Complex Electrical Issues
If you suspect that the issue may be related to the vehicle’s wiring or electronics, obtaining help from a certified technician is recommended. These professionals are equipped with the diagnostic tools necessary to identify the root cause of electrical problems.
2. Advanced Key Fob Issues
Some concerns regarding the key fob may require specialized knowledge. Therefore, if the fob is damaged beyond a simple battery replacement or program, you may need to consider a replacement from your Subaru dealer.
3. Security System Malfunctions
If there are overarching issues with your vehicle’s security system, like the alarm going off unexpectedly, you should contact a Subaru dealer. They can diagnose the security system’s functionality and offer solutions.
Preventive Measures: Ensuring Longevity of Your Key Fob
Taking care of your key fob can extend its lifespan and prevent future problems. Here are some preventive measures you might consider:
1. Regular Battery Changes
Replace the battery every one to two years to ensure your key fob operates smoothly.
2. Keep the Fob Away from Extreme Temperatures
Heat and cold can significantly affect battery life. Avoid leaving your key fob in extreme temperatures, such as a hot car in the summer or a freezing car in the winter.
3. Avoid Physical Damage
Store your key fob in a safe place where it won’t get dropped or exposed to water. Consider using a protective case to minimize wear and tear.
4. Maintain Your Vehicle’s Electronics
Regularly servicing your vehicle can help ensure that any electronic issues are detected early, including those related to the key fob.
Conclusion
Understanding the common issues that can affect your Subaru remote key and knowing how to troubleshoot them is invaluable for any Subaru owner. Whether it’s a simple battery replacement, checking for signal interference, or reprogramming, most scenarios are manageable with a bit of knowledge and effort. However, when in doubt, don’t hesitate to consult professionals to keep your vehicle secure and functional.
Maintaining your remote key fob properly can lead to years of trouble-free use, ensuring that your Subaru remains as enjoyable to drive as it was the day you bought it!
What should I do if my Subaru remote key is not working?
If your Subaru remote key is not functioning properly, start by checking the battery within the remote. A dead battery is the most common issue with remote keys. You can easily replace it by opening the remote case, removing the old battery, and inserting a new one. Make sure to use the same type of battery as specified in your owner’s manual.
If replacing the battery does not resolve the issue, it may be necessary to reprogram the remote. This can often be done at home following specific steps outlined in your vehicle’s manual. If you’re unsure or are not comfortable doing this, consider visiting a Subaru dealership or a trusted automotive locksmith for assistance.
How can I tell if the key fob battery is dead?
You can usually tell if the key fob battery is dead if the buttons do not respond when pressed. Additionally, you might notice that the range of your remote is significantly reduced, meaning you have to be very close to the vehicle for it to work. If you experience these symptoms, the battery is likely the issue.
Another indicator can be visual inspection. Many key fob designs have a small LED light that illuminates when you press a button. If you press a button and the light doesn’t turn on, it’s a strong sign that the battery needs replacing. Always refer to your vehicle’s manual for guidance on battery type and replacement instructions.
Can I reset my Subaru remote key on my own?
Yes, many Subaru models allow you to reset or reprogram your remote key on your own, but the procedures can vary between models and years. Typically, the process involves a series of steps you need to follow within a specific time frame. Checking the owner’s manual will provide you with the exact steps required for your vehicle.
However, if you find the process challenging or you’re unable to reset the remote, it might be beneficial to consult with a professional. Visiting a Subaru dealership or an automotive locksmith can provide you with expert assistance, ensuring your remote key is functioning correctly without any issues.
What if my Subaru remote key is lost or stolen?
If your Subaru remote key is lost or stolen, it’s important to act quickly to prevent unauthorized access to your vehicle. Start by using the spare key if you have one. Additionally, consider changing the locks or reprogramming the vehicle’s computer to ensure that the lost key can no longer access your car.
You will likely need to visit a Subaru dealership to obtain a replacement key fob. They can also assist you in reprogramming the vehicle if necessary. It’s important to provide documentation such as proof of ownership to ensure that the key is replaced safely and securely.
Can I use an aftermarket key fob for my Subaru?
While it is possible to find aftermarket key fobs for your Subaru, it’s generally recommended to use original equipment manufacturer (OEM) parts. Aftermarket key fobs may not always function correctly with your vehicle’s specific systems or may require additional programming that can be more complex than with an OEM key.
If you decide to go with an aftermarket option, ensure that it’s a reputable product from a trusted source. Verify compatibility with your Subaru model and consult with a professional if you have any doubts about the quality or functionality of the replacement key fob.
How much does it cost to replace a Subaru key fob?
The cost to replace a Subaru key fob can vary widely depending on several factors, including your vehicle model, the type of key fob needed, and whether you go through a dealership or an aftermarket service. Generally, you can expect the price to range from $100 to $300, including programming fees.
If you opt for an aftermarket key fob, it could be less expensive, but you should consider the potential risks involved with quality and compatibility. Always get a quote in advance and ensure that all costs are clearly outlined to avoid unexpected charges during the replacement process.
