Key Fob Doesn’t Open Trunk Subaru

If your key fob doesn’t open your Subaru’s trunk, you’re not alone. This is a common issue that can be frustrating, but often has a simple solution. This article will guide you through the most common causes and solutions, whether you’re a car owner, a mechanic, or an automotive technician.

Why won’t my Subaru key fob open the trunk? Several reasons can contribute to this problem, from a dead key fob battery to a faulty trunk release switch or even a programming issue. Let’s delve into the most likely culprits and how to troubleshoot them.

Common Reasons Your Subaru Key Fob Won’t Open the Trunk

Several factors can cause your key fob to malfunction. Here are some of the most common reasons your key fob doesn’t open trunk subaru:

• Dead Key Fob Battery: The most frequent cause is a simple dead battery in the key fob. Without sufficient power, the key fob can’t transmit the signal to your car. Replacing the battery is usually a quick and easy fix.
• Faulty Trunk Release Switch: The trunk release switch itself might be malfunctioning. This switch can become worn or damaged over time, preventing the signal from reaching the trunk latch.
• Key Fob Programming Issues: Sometimes, the key fob loses its programming and needs to be reprogrammed to communicate with your Subaru’s system. This often requires a specific procedure or professional assistance.
• Fuse Problems: A blown fuse related to the trunk release system can also cause this issue. Check your Subaru’s owner’s manual to locate the correct fuse and inspect it for damage.
• Wiring Problems: Damaged or corroded wiring between the key fob receiver and the trunk release mechanism can interrupt the signal. This is less common but requires a more thorough inspection.
• Trunk Latch Malfunction: In some cases, the problem isn’t with the key fob but with the trunk latch itself. The latch mechanism might be stuck or broken, preventing it from opening even with a working key fob.

How to Fix a Subaru Key Fob That Won’t Open the Trunk

Now, let’s explore how to address each of these potential problems:

1. Replace the Key Fob Battery: This is the easiest fix and often solves the problem. Consult your Subaru owner’s manual for instructions on how to access and replace the battery in your specific key fob model. You can usually find replacement batteries at most electronics stores.

2. Check the Trunk Release Switch: Try opening the trunk using the release switch inside the car. If this works, the problem likely lies with the key fob itself. If not, the switch may be faulty and needs replacing. Much like the [2018 subaru impreza key fob], the location of this switch can vary depending on the model.

3. Reprogram the Key Fob: If replacing the battery doesn’t work, you might need to reprogram the key fob. Some Subarus have a DIY reprogramming procedure outlined in the owner’s manual.

5. Check for Wiring Issues: Inspect the wiring connected to the trunk release mechanism for any signs of damage or corrosion. This might require removing some trim panels to gain access. If you’re uncomfortable with this, it’s best to seek professional assistance. Similar troubleshooting steps might be required for other Subaru models, such as the [2015 subaru legacy key fob].

If you’ve tried all the above steps and your key fob still doesn’t open the trunk, it’s best to consult a qualified Subaru technician or automotive locksmith.
