How to Unlock Subaru with Key

Unlocking your Subaru with a key is simple when you know the right steps. Whether you’re dealing with a locked door, a dead fob battery, or an older model, this guide covers everything you need—from basic key insertion to advanced troubleshooting.

Key Takeaways

• Use the physical key blade: Every Subaru key fob has a hidden metal key that can manually unlock the driver’s door.
• Locate the keyhole correctly: The keyhole is often hidden under a small cover on the driver’s door handle—press or slide to reveal it.
• Turn the key smoothly: Insert the key fully and turn it clockwise to unlock all doors on most Subaru models.
• Check for key fob battery issues: A dead fob battery won’t prevent manual unlocking, but it may cause confusion about whether the car is locked.
• Know your model year: Older Subarus (pre-2010) may have exposed keyholes, while newer ones require releasing a cover.
• Call for help if stuck: If the key won’t turn or the door won’t open, avoid forcing it—contact roadside assistance or a locksmith.
• Prevent future lockouts: Keep a spare key in a secure location and consider upgrading to a keyless entry system.

Introduction: Why Knowing How to Unlock Subaru with Key Matters

We’ve all been there—standing in the rain, late for work, only to realize your Subaru key fob isn’t responding. Maybe the battery died, or you accidentally locked the keys inside. In moments like these, knowing how to unlock Subaru with key isn’t just convenient—it’s essential. Unlike some modern cars that rely entirely on electronic access, Subaru still equips its vehicles with a physical key backup, giving you a reliable fallback when technology fails.

Subaru has long prioritized safety, reliability, and practicality. That philosophy extends to their key systems. Whether you drive a rugged Outback, a sporty WRX, or a family-friendly Forester, every Subaru comes with a mechanical key option. This means even if your key fob stops working, you’re never truly locked out. Understanding how to use this feature can save you time, stress, and potentially hundreds of dollars in locksmith fees.

But here’s the catch: the process isn’t always obvious. On newer models, the keyhole is cleverly hidden to maintain the car’s sleek design. If you’ve never used it before, you might not even know where to look. That’s why this guide exists—to walk you through every step, from finding the keyhole to turning the key smoothly, no matter your Subaru model or year.

Understanding Your Subaru Key System

Before diving into the unlocking process, it helps to understand how Subaru’s key system works. Most Subarus come with a key fob that combines remote locking, unlocking, and sometimes even push-button start. But beneath that high-tech exterior lies a simple metal key blade—your mechanical backup.

This dual-system design is intentional. Subaru knows that electronics can fail. Batteries die. Signals get blocked. In those moments, the physical key ensures you can still get into your vehicle. It’s a smart, user-friendly approach that reflects Subaru’s commitment to real-world usability.

There are two main types of Subaru keys:

Traditional Key Fob with Removable Blade: Common in models from the early 2000s to around 2015, these fobs have a small release button or switch that lets you pop out a metal key. You can use this key to manually unlock the driver’s door.

Integrated Key Fob (Keyless Entry): Found in newer models (2016 and later), these fobs often look like a solid piece of plastic. The key blade is hidden inside and must be released using a small lever or button, usually near the base of the fob.

Regardless of the type, the principle is the same: the key operates the driver’s door lock mechanically. Once you unlock that door, you can usually access the interior and restart the vehicle—even if the fob battery is dead.

How the Mechanical Lock Works

The driver’s door on every Subaru has a traditional cylinder lock. When you insert the key and turn it, it physically moves the locking mechanism inside the door. This is different from electronic locks, which rely on signals from the fob.

This mechanical system is robust and rarely fails. However, it can get stiff in cold weather or if dirt and debris build up over time. That’s why regular maintenance—like cleaning the keyhole and using a silicone-based lubricant—can keep things running smoothly.

It’s also worth noting that turning the key usually unlocks all doors, not just the driver’s side. This is a safety feature designed to let passengers exit quickly in an emergency. However, some older models may only unlock the driver’s door on the first turn, requiring a second turn to unlock the rest.

Key Fob Battery vs. Mechanical Key

A common misconception is that a dead key fob battery will lock you out of your Subaru. That’s not true. The fob’s battery only powers the remote functions—like locking, unlocking, and trunk release. The mechanical key operates independently.

So even if your fob is completely dead, you can still use the physical key to get in. This is especially helpful if you’re in a parking garage with poor signal reception or if the fob’s internal electronics have failed.

However, once you’re inside, you may not be able to start the car without a working fob—especially on models with push-button ignition. In those cases, Subaru includes a backup method: placing the fob in a designated slot (often near the steering column) to allow the engine to start via inductive coupling.

Step-by-Step Guide: How to Unlock Subaru with Key

Now that you understand the basics, let’s walk through the actual process of unlocking your Subaru with a key. Follow these steps carefully, and you’ll be back on the road in minutes.

Step 1: Locate the Keyhole on the Driver’s Door

The first challenge is finding the keyhole. On older Subaru models (pre-2010), it’s usually visible—a small, round opening on the driver’s door handle. But on newer models, Subaru hides it under a protective cover to maintain the car’s clean lines.

To find it:

– Look at the driver’s door handle. You’ll see a small, rectangular or oval-shaped cover.
– This cover is often flush with the handle and may have a subtle seam or indentation.
– Gently press or slide the cover to release it. On some models, you’ll need to use the key itself to pry it open.

For example, on a 2020 Subaru Outback, the cover is located on the top of the door handle. Press the small tab with your fingernail or the edge of the key, and it will pop open to reveal the keyhole.

Step 2: Retrieve the Physical Key from the Fob

Next, you’ll need to access the metal key blade inside your key fob.

If you have a traditional fob:

– Look for a small button or switch on the side or top of the fob.
– Press it and pull out the key blade. It should slide out smoothly.

If you have an integrated fob (common in newer models):

– Find the small release lever near the base of the fob. It’s usually a tiny switch or button.
– Slide or press it, and the key blade will pop out.

Tip: Practice this at home when you’re not in a rush. It’s easier to learn the mechanism when you’re calm and have good lighting.

Step 3: Insert the Key into the Keyhole

Once you’ve exposed the keyhole and retrieved the key, it’s time to insert it.

– Hold the key with the teeth facing downward (this is the standard orientation).
– Gently insert the key into the cylinder. It should go in smoothly—don’t force it.
– Push it all the way in until it stops.

If the key doesn’t go in easily, double-check the orientation. Some keys are symmetrical and can go in either way, but most have a specific direction.

Step 4: Turn the Key to Unlock the Door

This is the moment of truth.

– Turn the key clockwise (to the right) about 90 degrees.
– You should feel a solid click as the lock mechanism engages.
– On most Subaru models, this will unlock all doors simultaneously.

If the key turns but the door doesn’t open, try gently pulling the handle from the outside. Sometimes the lock releases, but the door remains closed due to weather stripping or a slight misalignment.

Step 5: Open the Door and Enter the Vehicle

Once the lock disengages, pull the door handle to open it. You should now have full access to the interior.

At this point, you can sit in the driver’s seat and assess the situation. If your key fob battery is dead, you may need to replace it. If you’ve locked the keys inside, you can now retrieve them.

Step 6: Start the Engine (If Needed)

If your Subaru has a push-button start and the fob battery is dead, you’ll need to use the backup start method.

– Look for a small slot or tray near the steering column—often labeled “Fob Slot” or “Key Backup.”
– Place the entire key fob into this slot.
– Press the brake pedal and push the start button. The car should recognize the fob via proximity and allow the engine to start.

This feature is available on most 2015 and newer Subaru models with keyless ignition.

Troubleshooting Common Issues

Even with the right steps, things don’t always go smoothly. Here are some common problems and how to fix them.

Key Won’t Turn in the Lock

If the key inserts but won’t turn, don’t force it. Forcing can break the key or damage the lock cylinder.

Possible causes:

– Frozen lock: In cold weather, moisture can freeze inside the cylinder. Use a lock de-icer spray or gently warm the key with a lighter (don’t overheat it).
– Dirt or debris: Over time, dust and grime can build up. Spray a small amount of silicone-based lubricant into the keyhole and try again.
– Worn key or lock: If the key is old or damaged, it may not engage properly. Try a spare key if available.

Keyhole Cover Won’t Open

If the cover over the keyhole won’t budge:

– Make sure you’re pressing the right spot. Look for a small indentation or seam.
– Use the edge of the key to gently pry it open—don’t use excessive force.
– If it’s stuck due to dirt or paint, clean around the edges with a soft cloth.

Door Unlocks But Won’t Open

Sometimes the lock releases, but the door remains shut. This can happen if:

– The door is frozen to the frame in winter.
– The weather stripping is compressed or dirty.
– The child safety lock is engaged (though this affects the inside handle, not the outside).

Try gently pulling the handle while rocking the door slightly. If it’s frozen, use a hairdryer or de-icer spray.

Key Broke Off in the Lock

This is rare but possible. If the key snaps:

– Stay calm. Don’t try to dig it out with tools.
– Use needle-nose pliers to gently grip the exposed end and pull it out.
– If it’s flush or recessed, contact a professional locksmith. They have specialized tools to extract broken keys without damaging the lock.

Preventing Future Lockouts

The best way to deal with a lockout is to avoid it altogether. Here are some practical tips to keep you from needing to unlock Subaru with key in the first place.

Keep a Spare Key Handy

Always have a spare key in a secure location. Options include:

– A magnetic key box hidden under the car (e.g., behind the bumper or under the chassis).
– A trusted family member or friend who lives nearby.
– A lockbox at your workplace or home.

Avoid hiding keys in obvious places like under the doormat or in a fake rock—thieves know these spots.

Replace the Key Fob Battery Regularly

Most key fob batteries last 2–3 years. When the remote starts acting sluggish—like requiring you to be closer to the car—it’s time for a replacement.

Use a CR2032 battery (common in most Subaru fobs) and follow the manufacturer’s instructions to open the fob. Keep a spare battery in your glove compartment.

Use a Keyless Entry Upgrade

If you frequently forget your keys or want added convenience, consider upgrading to a keyless entry system. Some options include:

– Subaru’s factory-installed keyless access (available on higher trims).
– Aftermarket smart locks that work with your smartphone.
– Bluetooth-enabled key finders that attach to your keychain.

These systems reduce reliance on physical keys while maintaining security.

Regular Maintenance of the Lock Cylinder

To keep the mechanical lock working smoothly:

– Clean the keyhole every 6 months with compressed air.
– Apply a small amount of silicone spray or graphite lubricant (never oil-based products, which attract dirt).
– Test the key monthly to ensure it turns easily.
