If your 2011 WRX trunk won’t open with either key fob, you’re not alone. This is a common issue that can be caused by a number of factors. This guide will walk you through the most common culprits and provide solutions so you can get back to hauling groceries, sports gear, or whatever else you need to carry in your Subaru.
Understanding the Problem: Why Your 2011 WRX Trunk Won’t Open
So, your 2011 WRX trunk has decided to take a vacation, huh? It happens. Let’s dive into the “why” before we get to the “how to fix it.” It’s important to understand that a few different things could be the cause, ranging from a simple dead key fob battery to a more complex electrical issue. Pinpointing the source of the problem is the first step toward getting your trunk back in working order.
Key Fob Battery Issues
The most obvious culprit is a dead key fob battery. It’s a quick and easy check. Try replacing the batteries in both your key fobs. Yes, both! Sometimes a weak battery in one fob can interfere with the other. This is a cheap and easy fix and might save you a lot of headache down the line. Imagine the frustration of tearing your car apart only to realize it was just a dead battery!
Fob Programming Problems
Sometimes, the key fobs can lose their programming. This could be due to a variety of reasons, from accidental deprogramming to electrical interference. Reprogramming the fobs might be the solution. Check your owner’s manual for instructions or consider contacting a Subaru dealership or a qualified locksmith.

Fuse Problems: Checking the Fuse Box
Next up, fuses. Fuses are the safety nets of your car’s electrical system. They’re designed to blow before a larger electrical problem occurs. Locate your fuse box (your owner’s manual is your friend here) and check the fuse related to the trunk release. If it’s blown, replace it with a new fuse of the same amperage. Remember, don’t put a higher amperage fuse in – that’s like playing with fire, electrically speaking.
Wiring Issues: Inspecting the Wiring Harness
Wiring issues can be a bit more tricky to diagnose. Look for any signs of damage, corrosion, or loose connections in the wiring harness leading to the trunk release mechanism. This might involve removing some interior panels to get a better look. If you’re not comfortable doing this yourself, a mechanic can help.
Trunk Latch and Release Mechanism Malfunctions
Sometimes, the mechanical components of the trunk release can fail. The latch itself could be stuck, or the release mechanism might be broken. This might require replacing the entire assembly. Again, a mechanic can assist with this.
Faulty Actuator: A Common Culprit
The actuator is the small motor that actually opens the trunk lock. These can sometimes fail due to age, wear and tear, or corrosion. If you suspect the actuator is the issue, replacing it is usually the best course of action.

Troubleshooting Your 2011 WRX Trunk Release
Now, let’s put all this information into action. Here’s a step-by-step guide to troubleshooting your trunk release issue.
- Check the key fob batteries. Replace them with fresh batteries.
- Try the physical key. Many WRX models have a physical key hidden within the key fob. This key can often be used to manually unlock the trunk.
- Check the fuses. Locate and inspect the trunk release fuse in the fuse box. Replace if necessary.
- Inspect the wiring. Look for any signs of damage, corrosion, or loose connections in the wiring harness leading to the trunk release.
- Test the actuator. If you’re mechanically inclined, you can try testing the actuator with a multimeter to see if it’s receiving power.
