When you find out that your Subaru access key has been disabled, it can be a little confusing and stressful. After all, your car’s key is crucial to starting your car and getting on the road. Whether you’re locked out or simply can’t start your Subaru, understanding why this happens and how to fix it is important. In this article, we’ll explore everything you need to know about the Subaru access key being disabled, including how to fix it and what might cause the problem.
What Happens When Your Subaru Access Key is Disabled?
The Subaru access key is an essential component of your vehicle’s keyless entry and ignition system. If it becomes disabled, you might experience a few different problems. The most common issue is that your Subaru won’t start or recognize the key. This can be frustrating because the car won’t turn on, and you might not be able to get into it, either.
A disabled access key can happen for a number of reasons. It could be because of a problem with the key itself, the car’s computer system, or even a simple issue with the battery inside your key. Understanding the possible causes can help you figure out why it happened and how to fix it.
Why Your Subaru Access Key Might Get Disabled
There are several reasons why your Subaru access key could get disabled. Here are the most common ones:
Battery Issues: The most common reason for a disabled key is a dead battery inside the key fob. If the key fob’s battery is dead, it won’t send the signal needed to unlock or start the car. Fortunately, this is one of the easiest issues to fix.
Key Fob Malfunction: Over time, the key fob might simply stop working due to internal malfunctions. If the button inside the key is broken or the internal components get damaged, it can prevent the key from working properly.
Programming Issues: Your Subaru’s computer system needs to recognize the key in order for it to work. Sometimes, due to a software glitch or reset, the car’s system can lose its connection with the key. This may require reprogramming the key to sync it back with the vehicle.
Key Fob Deactivation: In some cases, Subaru’s system might deactivate the key as a security measure. This can happen if the key is detected as lost, stolen, or if there was an attempt to access the vehicle without proper authorization.
Interference: Sometimes, there can be external factors that cause interference with the signal from your key fob. This could include nearby electronics, other radio signals, or even strong magnets that disrupt the communication between the key fob and the car.
Signs That Your Subaru Access Key is Disabled
Before you start troubleshooting, it’s important to know the signs of a disabled access key. Here are a few things you might notice:
- Your car doesn’t respond when you press the unlock button on the key fob.
- The car doesn’t start, even when the key fob is inside the vehicle.
- The key fob’s buttons seem unresponsive or jammed.
- The indicator light on the key fob doesn’t light up when you press any buttons.
If you notice any of these signs, it’s likely that the key has been disabled or is malfunctioning.
How to Fix a Disabled Subaru Access Key
If your Subaru access key is disabled, don’t panic! There are several ways you can try to fix the issue. Let’s walk through the most common solutions, step by step, so you can get your key working again and get back on the road.
1. Check and Replace the Battery in Your Key Fob
One of the easiest fixes for a disabled Subaru access key is replacing the battery in the key fob. If the battery is dead, the key won’t be able to send a signal to the car. Fortunately, changing the battery is simple and only takes a few minutes.
Here’s how you can replace the battery in your Subaru key fob:
- Step 1: Use a small flathead screwdriver to open the key fob. There will usually be a seam where you can gently pry the two halves apart.
- Step 2: Once open, carefully remove the old battery. Pay attention to how the battery is positioned so you can insert the new one correctly.
- Step 3: Insert the new battery, making sure it fits snugly in place. Be sure to use the correct battery type, which is usually a CR2032 or similar.
- Step 4: Close the key fob back together and test it. Press any button on the fob to see if the indicator light turns on and if the car responds.
If replacing the battery fixes the issue, you’re good to go! If not, keep reading for other solutions.
2. Reprogram the Key Fob to Your Subaru
If changing the battery didn’t work, the next step is to try reprogramming the key. Sometimes, the connection between the key fob and your car’s computer system can get lost. Reprogramming it can restore the connection and get it working again.
Reprogramming a Subaru access key is a bit more complex than changing the battery, but it’s still something you can do yourself. Here’s how to do it:
- Step 1: Get inside your Subaru and close all the doors.
- Step 2: Insert your key into the ignition and turn it to the “On” position (but don’t start the car).
- Step 3: Press and hold the “Lock” button on the key fob for about 10 seconds.
- Step 4: You should hear a beep or see the lights flash, indicating that the car is now in programming mode.
- Step 5: Press the “Unlock” button on the key fob and hold it for another 10 seconds. After that, the key should be successfully reprogrammed.
If this doesn’t work, you may need to contact your dealership or a professional to help reprogram the key.
3. Check for Interference
If the key fob still isn’t working after replacing the battery and reprogramming it, there might be interference preventing the signal from being received. This could be caused by nearby electronics, radio signals, or strong magnets.
To test for interference, try moving your car and key fob to a different location. If the key works in a different spot, you might have found the source of the interference. Moving away from the source of interference may solve the problem.
4. Visit Your Subaru Dealer for Assistance
If you’ve tried all of the above solutions and your Subaru access key is still disabled, it may be time to visit a Subaru dealership or a professional locksmith. The issue could be more complex, such as a malfunction with your car’s computer system or a deeper issue with the key fob.
At the dealership, a technician can use special diagnostic tools to check if there are any issues with the car’s computer system or if the key needs to be replaced. While this option may involve some cost, it’s often the best choice for complicated problems.
Preventing Access Key Issues in the Future
No one likes dealing with a disabled access key, so here are a few simple tips to help prevent the issue from happening again in the future:
- Regularly replace the key fob battery: Even if the key still works, it’s a good idea to replace the battery every 1-2 years to avoid unexpected issues.
- Keep your key fob clean: Dirt and grime can interfere with the key fob’s buttons and signal. Clean the key fob regularly with a soft cloth.
- Store your key fob properly: Avoid dropping your key fob or exposing it to extreme temperatures, which could cause internal damage.
- Limit exposure to interference: Be mindful of where you store your key. Keep it away from strong magnets or electronics that could cause signal interference.
By following these simple steps, you can help keep your Subaru access key in good working condition for years to come.
