When it comes to reliability, few automotive brands can boast the same level of trust as Subaru. Yet, like any vehicle, Subarus are not immune to the occasional hiccups, particularly when it comes to their keys. It can be frustrating to find yourself in a situation where your Subaru key is not working. Whether your key is unresponsive, getting stuck, or failing to unlock your doors, understanding the reasons behind these issues can save you time and money. In this comprehensive guide, we will explore the common causes of Subaru key problems, provide troubleshooting tips, and detail possible solutions.
Understanding Key Functionality
Before diving into troubleshooting techniques, it’s essential to understand how your Subaru key works. The key fob communicates with your vehicle through radio frequency identification (RFID). When you press a button, the fob sends an encrypted signal to the vehicle, allowing you to unlock doors, start the ignition, and more.
Types of Keys for Subaru Vehicles
Subaru vehicles often come with different types of keys, including:
- Traditional Metal Keys: Older models typically use traditional mechanical keys that do not require a battery.
- Key Fobs: Newer models utilize electronic key fobs equipped with buttons for unlocking doors and starting engines.
- Smart Keys: The most advanced models feature smart keys that allow for keyless entry and start.
Each type of key has specific vulnerabilities, which can lead to problems.
Common Causes of Subaru Key Malfunctions
When your Subaru key is not working, there could be various reasons behind it. Let’s explore the most common issues:
1. Battery Issues
One of the most frequent reasons for a non-working key fob is a depleted battery. Key fobs typically use a small coin-cell battery, which has a limited lifespan.
Signs of a Low Battery
- Reduced range when trying to unlock doors
- Needing to press buttons multiple times

3. Programming Issues
Subaru keys can sometimes lose their programming, especially after a battery replacement or if you’ve recently changed your vehicle’s onboard computer settings.
Indicators of a Programming Issue
- The ignition does not recognize the key
- Emergency key works, but the fob does not
- Key lights up, but functions remain inactive
4. Lock and Ignition Cylinder Problems
The issue may not lie with the key itself but rather with the ignition or door lock cylinders. Dirt, debris, or wear can impede the smooth operation of these components.
Signs of Cylinder Problems
- Key gets stuck in the ignition
- Difficulty turning the key in the lock
- No response from the ignition with the key inserted

What should I do if my Subaru key fob isn’t working?
If your Subaru key fob isn’t functioning, the first step is to check the battery. Key fobs often use a small coin-cell battery, and it can drain over time due to usage or environmental conditions. Open the fob and inspect the battery’s condition. If it’s corroded or appears low on charge, replacing it could solve the problem.
After replacing the battery, test the key fob again. If it still doesn’t work, the issue might be more complex, such as a malfunctioning key fob or a problem with the car’s receiver. In this case, it can be beneficial to consult your vehicle manual for specific troubleshooting steps or seek a professional technician’s assistance to diagnose the issue further.
How can I reprogram my Subaru key fob?
Reprogramming your Subaru key fob can often resolve issues where the fob is not working as intended, especially after changing the battery. To reprogram your fob, start by getting into your Subaru and closing all the doors. Insert the key into the ignition and turn it to the ‘On’ position, then back to ‘Off’ without starting the engine.
You will typically need to repeat this process several times, turning the key in and out of the ignition to activate the fob programming mode. Follow specific instructions for your Subaru model, as they can vary. Once completed, test the fob to see if it’s functioning correctly; you might need to repeat the procedure if it doesn’t work on the first try.
Why won’t my Subaru ignition recognize my key?
If your Subaru ignition isn’t recognizing your key, there could be several reasons for this issue. One common cause is a problem with the key itself, particularly if it’s a worn or damaged key. Over time, the transponder chip embedded in the key can become unreadable if the key has been excessively worn down or has suffered damage.
Another potential reason is a malfunction in the ignition cylinder. Sometimes, dirt or debris can accumulate in the ignition, preventing it from recognizing the key. If cleaning the ignition doesn’t help, it may be necessary to consult a professional to inspect both the key and the ignition system for further issues.
What should I check if my Subaru keyless entry is not working?
When the keyless entry system on your Subaru fails to work, start by verifying that your key fob is not just out of battery. A dead battery is a common and easily fixable issue. Replace the battery, and if the key fob still doesn’t work, check for any physical damage to the fob that could prevent it from transmitting signals.
If the key fob appears to be in good shape and the battery is fresh, consider checking the car’s fuses related to the keyless entry system. A blown fuse can cause the system to fail. If everything seems intact but the issue persists, consulting your Subaru dealership or a qualified technician may help identify and address any underlying electrical problems.
Can I start my Subaru without the key fob?
Starting your Subaru without the key fob can be tricky, especially if your vehicle is equipped with an advanced security system. Most modern Subaru models use a push-to-start system that requires the key fob to be present for the engine to start. If you’re locked out or have lost your fob, you’ll need a replacement or spare to initiate the start sequence.
If your Subaru is an older model with a traditional key ignition, you can still start the car using a physical key. However, if your ignition system has a transponder chip, make sure the key is programmed to the vehicle. Otherwise, the car won’t start even with a physical key present, as the system won’t recognize it.
What can cause my Subaru key fob to malfunction unexpectedly?
A key fob can malfunction due to a variety of unforeseen circumstances. Environmental factors such as extreme temperatures can impact battery life and the internal mechanisms of the fob. Additionally, exposure to moisture can cause corrosion on internal components or within the battery compartment, leading to failure.
Unexpected electromagnetic interference from nearby devices or systems can also affect the fob’s performance. If you’ve recently experienced any of these conditions and your key fob has started malfunctioning, this could be the culprit. In such cases, replacing the battery and ensuring the fob is kept in a suitable environment can help restore its functionality.
Is it possible to get a replacement for a lost Subaru key fob?
Yes, it is possible to obtain a replacement key fob for a lost Subaru key. However, the process may vary depending on your vehicle model and year. Typically, you can visit your local Subaru dealership, where they can assist you in procuring a new fob. This process may involve providing proof of ownership and identification to ensure security.
Alternatively, some locksmiths offer replacement services for car keys and key fobs. They may have the capability to program a new fob to work with your vehicle. Nevertheless, ensure that the locksmith you choose is reliable and has experience with Subaru vehicles, as proper programming is essential for functionality.
