If you’ve ever found yourself standing in a parking lot, fumbling through your pockets for your Subaru key only for it not to work, you know how frustrating it can be. Subaru vehicles are renowned for their reliability and performance, but like all mechanical systems, sometimes things can go awry. This article will delve into the common problems associated with Subaru keys not working, how to troubleshoot these issues, and solutions to get you back on the road in no time.
Understanding Subaru Key Systems
Before diving into troubleshooting, it’s important to understand the different key systems used in Subaru vehicles. Over the years, Subaru has incorporated various technologies in their key fobs and ignition systems, and knowing which type you have can significantly help in determining the problem.
Types of Subaru Keys
Subaru keys can generally be categorized into three types:
- Traditional Metal Keys: These are standard mechanical keys that simply turn the ignition.
- Transponder Keys: Equipped with a chip that sends a signal to the car to allow it to start. If the chip isn’t recognized, the vehicle won’t start.
- Key Fobs: These remote controls may offer keyless entry and start features. They generally operate using a battery.
Understanding which key your Subaru uses can help you better diagnose your issue.
Common Reasons Subaru Keys Fail
If your Subaru key isn’t working, the problem could stem from various sources. Here, we will break down the most common issues that can prevent your key from functioning properly:
1. Dead Key fob Battery
A dead battery in your key fob is one of the most prevalent issues that can lead to malfunctioning. The fob may appear fine externally, but without a working battery, it won’t send the necessary signals to your car.
2. Failed Transponder Chip
If you have a transponder key, the chip inside could have failed. This chip is essential for communication between the key and the vehicle’s computer system. If the chip fails, the car won’t recognize the key, leading to starting issues.
3. Physical Damage
Sometimes, keys can suffer from physical damage. This damage can occur from dropping, bending, or water exposure. Inspect your keys for signs of wear and tear that may prevent them from working properly.
4. Key Cloning or Malfunctioning Programming
If you recently had a new key made, it’s possible that it wasn’t properly programmed to your vehicle. Cloning of keys can occur due to improperly set up equipment, leading to issues in functionality.
How to Troubleshoot Subaru Keys Not Working
If you’re experiencing problems with your Subaru key, troubleshooting the issue will help identify the root cause. Here’s how you can go about it:
1. Check the Key Fob Battery
Start with the simple solution—check the key fob battery.
Steps to Replace the Key Fob Battery
- Open the Key Fob: Use a small flathead screwdriver to gently pry apart the two halves of the fob.
- Remove the Old Battery: Take out the old battery and note its orientation.
- Insert the New Battery: Insert the new battery in the same orientation as the old one.
- Reassemble the Key Fob: Snap the two halves back together until they click.
Once you’ve replaced the battery, try using the key fob again to see if the issue is resolved.
2. Inspect the Physical Condition of the Key and Fob
Check your key and fob for signs of damage. Look for:
- Cracks or chips in the casing
- Signs of excessive wear on the key blade
If you notice any of these issues, it may be time to replace the key or the fob entirely.
3. Reprogram the Key Fob or Transponder Key
If the key still isn’t working after replacing the battery, you may need to reprogram it. Refer to your owner’s manual for specific instructions or consult with a Subaru dealership for professional help.
DIY Key Programming
For some models, you might be able to reprogram your key by following these general steps:
- Enter your vehicle with the key
- Turn the ignition to the ‘ON’ position and then ‘OFF’ eight times
- Press the lock button on the key fob while the ignition is in the ‘ON’ position
- Turn off and remove the key from the ignition
Your vehicle may now recognize the new key.
4. Test the Vehicle’s Ignition System
If the key works but your vehicle still won’t start, the problem might lie not with the key but with the engine start system or ignition barrel. Check for:
- Loose wiring connections: Especially around the ignition and steering column.
- Faulty ignition switch: This could prevent the vehicle from starting even with a recognized key.
Consult with a professional mechanic if you suspect an issue with the ignition system.
When to Contact a Professional
While many key issues can be resolved through these troubleshooting steps, some situations warrant professional attention:
1. Complex Key Systems
For vehicles with advanced keyless entry and start systems or if multiple keys aren’t working, it’s best to consult with your Subaru dealer. They have the right tools and diagnostics to address the problem accurately.
2. Mechanical Failures
If your Subaru has issues that are mechanical in nature rather than electronic—such as a stuck ignition cylinder—visiting a qualified mechanic or dealership is essential.
3. Lost or Stolen Keys
If you’ve lost your keys or suspect they’ve been stolen, it’s critical to have them deactivated. A dealership can help you set up a new key and protect your vehicle from theft.
Preventative Measures to Avoid Key Issues
To minimize the chances of experiencing key-related problems in the future, consider the following preventative measures:
1. Regular Battery Checks
Make it a routine to check the key fob battery every six months. This small maintenance step can avoid unexpected failures.
2. Proper Key Handling
Handle your keys with care to avoid physical damage. Keep your keys in a designated spot to minimize wear and tear.
3. Keep Backup Keys
Having a spare key on hand can save time and stress in case of malfunctions. Consider keeping one in a safe place, such as with a family member or in a secure location at home.
Conclusion
In conclusion, while Subaru keys can occasionally malfunction, understanding the common flaws and knowing how to troubleshoot will ease the inconvenience. Whether it’s a dead battery, a damaged fob, or an issue with programming, many solutions are accessible for Subaru owners. Always remember that professional help is available for more complex issues.
By following the guidelines laid out in this article, you can ensure that your Subaru remains a reliable companion on the road and that you’re always prepared for the unexpected. Whether you are a long-time Subaru enthusiast or a new owner, maintaining your key system can enhance your vehicle experience and keep you worry-free. So, stay vigilant, and happy driving!
What should I do if my Subaru key won’t turn in the ignition?
If your Subaru key won’t turn in the ignition, the first step is to ensure that you’re using the correct key for your vehicle. Sometimes, a spare key is mistaken for the primary key due to similar appearance. If the key is correct, check if there is any debris or dirt around the ignition cylinder that might be obstructing movement. Cleaning around the ignition can often resolve minor issues.
Additionally, ensure that the steering wheel is not locked. If the steering wheel has been turned too far in either direction, it can put pressure on the ignition lock, preventing the key from turning. Gently jiggle the steering wheel while attempting to turn the key to see if that resolves the issue.
Why isn’t my Subaru key fob working?
If your Subaru key fob isn’t working, the most common reason is a depleted battery. Key fob batteries typically last several years, but they will eventually wear out. Check the battery by taking the fob apart to replace it, making sure to use the correct type. After replacing the battery, test the fob again to see if it responds.
If the battery replacement does not solve the issue, there may be a problem with the key fob itself or its connection to the vehicle’s system. In this case, you may need to reprogram the key fob or take it to a dealer for diagnosis. Sometimes, environmental factors or electronic interference can also disrupt the fob’s function.
How can I tell if my Subaru key is damaged?
To determine if your Subaru key is damaged, inspect it closely for any visible signs of wear or breakage. Look for cracks, chips, or significant bends in the key blade. If you notice any deformities, it’s likely that the key may not function properly. Additionally, check the key’s teeth to ensure they are not worn down excessively, as this can affect how the key engages the ignition.
Another indication of key damage can be intermittent or total failure to start your vehicle. If you notice that your key occasionally works or struggles to turn in the ignition, this may point to an underlying issue with the key itself. In such cases, it’s best to consult with a professional locksmith to evaluate whether the key can be repaired or if a replacement is necessary.
What could cause my Subaru key to stop working suddenly?
There are several reasons your Subaru key might stop working suddenly. One possibility is that the transponder chip embedded in the key has malfunctioned. This chip is essential for starting the vehicle, and any damage or electronic failure can render the key inoperative. Poor solder joints or exposure to moisture can also lead to key issues.
Another potential cause is a problem with the vehicle’s ignition system itself. Faulty ignition switches or wiring issues could prevent the key from activating the ignition, even if the key itself is in good condition. In such cases, a thorough inspection by a qualified technician may be necessary to pinpoint the root of the problem.
Can I program a new Subaru key myself?
Yes, in some instances, you can program a new Subaru key yourself, especially if it is a simple key without a transponder. However, if you are dealing with a transponder key or key fob, the programming process can be more complex and generally requires special tools or equipment. Some models may allow you to program a new key by following a series of steps detailed in the vehicle’s owner’s manual.
If you’re unsure about how to proceed or don’t feel comfortable programming the key yourself, it is advisable to seek assistance from a professional locksmith or your local Subaru dealership. They will have the necessary equipment and expertise to ensure that your new key is correctly programmed to work with your vehicle.
What should I do if I lost my only Subaru key?
If you’ve lost your only Subaru key, the first step is to remain calm and retrace your steps to try and locate it. However, if you are unable to find it, the next course of action is to contact your local Subaru dealership or a locksmith who specializes in automotive keys. They can assist you in obtaining a new key, but you will likely need to provide identification and proof of ownership.
Keep in mind that replacing a key can be costly, especially if it involves rekeying the ignition system to prevent unauthorized access. Some dealerships may also require you to provide the Vehicle Identification Number (VIN) to prepare a new key. Planning ahead by having a spare key made can save you trouble in the future.
Why is my Subaru remote starter not working?
If your Subaru remote starter is not working, start by checking the remote battery, as a dead battery can prevent it from sending signals to the car. Replacing the battery usually resolves the issue. Also, ensure that you are within the effective range of the remote starter as distance can affect the signal strength.
Additionally, verify that the remote starter system has not been disabled accidentally. Some vehicle settings or error messages may inhibit the remote start feature, especially if any of the doors are not properly closed or if the hood is ajar. Refer to your owner’s manual for troubleshooting guidance specific to your model.
How much does it cost to replace a Subaru key?
The cost to replace a Subaru key varies depending on the type of key, whether it has a transponder chip or is a key fob that requires additional programming. Typically, you can expect to pay anywhere from $50 to over $300. Basic metal keys are usually the least expensive, while smart keys or key fobs tend to be on the higher end of the spectrum due to their complexity.
When replacing a key through a dealership, the labor and programming fees can add to the overall cost. It’s often more economical to consult an automotive locksmith who can provide a quote and services tailored to your specific situation, so always shop around to find the best option.
