How to Unlock a Subaru with a Key: A Complete Guide

We’ve all been there—standing in the rain, late for work, only to realize your keys are locked inside your Subaru. It’s frustrating, stressful, and enough to ruin your morning. But before you panic or call a locksmith, know this: you can often unlock your Subaru with a key—even if you only have the fob in your hand. Yes, that sleek, high-tech key fob hiding in your pocket or purse usually contains a simple metal key that can save the day.

Subaru vehicles are designed with both convenience and security in mind. While many newer models come with push-button start and keyless entry, they still include a physical key as a backup. This means that even if your fob battery dies or you accidentally lock the keys inside, you’re not completely stuck. In this guide, we’ll walk you through exactly how to unlock a Subaru with a key—step by step. Whether you drive a Forester, Outback, Crosstrek, Impreza, or Legacy, the process is similar across most models. We’ll also cover troubleshooting tips, preventative measures, and what to do if the manual method doesn’t work.

Understanding Your Subaru Key Fob

Before diving into the unlocking process, it’s important to understand how your Subaru key fob works. Most modern Subarus come with a keyless entry fob that allows you to lock and unlock your car remotely. These fobs typically have buttons for locking, unlocking, opening the trunk, and activating the panic alarm. But what many drivers don’t realize is that these fobs also contain a hidden physical key—often referred to as the “emergency key” or “manual key.”

Where Is the Physical Key Located?

The physical key is stored inside the key fob itself. On most Subaru models, you’ll find a small button or latch on the side or top of the fob. Pressing this button releases a metal key blade that folds out or slides out. This key is designed specifically for manual entry in case of a dead battery, malfunctioning fob, or accidental lockout.

How to Access the Hidden Key

To access the hidden key, follow these simple steps:

• Hold the key fob with the Subaru logo facing up.
• Look for a small button or seam along the side of the fob—this is usually located near the top or middle.
• Press the button firmly. You should feel or hear a click.
• The metal key blade will pop out or slide out from the fob.

For example, on a 2022 Subaru Outback, the key release button is on the top edge of the fob. On a 2020 Crosstrek, it’s on the side. If you’re unsure, check your owner’s manual or look for a small indentation that suggests a movable part.

Why Subaru Includes a Physical Key

Subaru includes a physical key for several reasons. First, it’s a reliable backup when electronic systems fail. Second, it ensures you can still enter your vehicle in remote areas where cell service is unavailable. Third, it’s a security feature—some thieves target keyless entry systems, but a physical key adds an extra layer of protection. Finally, it’s required by law in many regions that vehicles have a manual override for door locks.

Step-by-Step: How to Unlock Your Subaru with a Key

Now that you know how to access the physical key, let’s walk through the actual process of unlocking your Subaru. This method works for the driver’s side door on most models. Once inside, you can start the car using the key fob or push-button start, depending on your vehicle.

Step 1: Locate the Keyhole on the Door

The first step is finding the keyhole. On most Subaru models, the keyhole is located on the driver’s side door, just below or beside the door handle. It’s often covered by a small plastic cap to protect it from dirt and weather. You may need to gently pry off the cap with your fingernail or a small tool.

For instance, on a 2021 Subaru Forester, the keyhole is on the front edge of the door handle. On a 2019 Impreza, it’s slightly lower, near the window frame. If you can’t see it, look for a small, round or oval opening—usually black or silver.

Step 2: Insert the Key into the Lock

Once you’ve located the keyhole, insert the metal key blade into the lock. Make sure the key is fully inserted and aligned properly. You may need to wiggle it slightly to ensure it’s seated correctly.

Tip: If the key doesn’t go in smoothly, don’t force it. Check that you’re using the correct key and that the lock isn’t obstructed by dirt or ice. In cold weather, the lock may freeze—use a de-icer spray or warm the key with your hands before inserting.

Step 3: Turn the Key to Unlock

After inserting the key, turn it clockwise (to the right) to unlock the door. You should hear a click, and the door should pop open. On some models, you may need to pull the door handle while turning the key.

Important: Only turn the key in the correct direction. Turning it counterclockwise may lock the door further or damage the mechanism. If the key won’t turn, double-check that it’s fully inserted and that the lock isn’t frozen or jammed.

Step 4: Enter the Vehicle and Start the Engine

Once the door is unlocked, open it and get inside. If your Subaru has a push-button start, you can now start the engine by pressing the button while holding the brake pedal. The key fob must be inside the vehicle for this to work—even if the battery is dead, the fob can often be detected when placed near the start button.

For models with a traditional ignition, insert the key fob into the ignition slot and turn it to start the engine. Some older Subarus may require the physical key to be used in the ignition, but most modern models use the fob as a transponder.

Troubleshooting Common Issues

Even with the right steps, you might run into problems when trying to unlock your Subaru with a key. Here are some common issues and how to solve them.

The Key Won’t Turn in the Lock

If the key won’t turn, it could be due to a few reasons. First, check if the lock is frozen—common in winter. Use a lock de-icer or gently warm the key with your hands. Never use hot water, as it can cause more ice to form inside the lock.

Second, the lock may be dirty or corroded. Over time, dirt, salt, and moisture can build up inside the keyhole. Use a silicone-based lubricant (not oil, which attracts dirt) to clean and lubricate the lock. Spray a small amount into the keyhole and insert the key several times to work it in.

Third, the key itself may be damaged. If the key blade is bent or worn, it may not engage properly with the lock. In this case, you’ll need a replacement key from a Subaru dealer or locksmith.

The Key Fob Battery Is Dead

A dead fob battery won’t prevent you from using the physical key to unlock the door, but it may cause issues when starting the car. Most Subaru fobs use a CR2032 coin cell battery, which lasts 2–3 years. If your fob isn’t responding, try replacing the battery.

To replace the battery, open the fob using a small screwdriver or the key blade itself. Remove the old battery, insert a new one (positive side up), and reassemble the fob. Test it by pressing the unlock button near the car.

Even with a dead battery, you can still start the car. Place the fob near the start button (usually in the center console or steering column) and press the button. The car should detect the fob’s transponder signal and allow you to start the engine.

The Keyhole Is Covered or Hard to Find

On some Subaru models, the keyhole is hidden under a cap or integrated into the door handle. If you can’t find it, consult your owner’s manual or look for a small seam or indentation. You can also search online for your specific model and year to see where the keyhole is located.

Tip: Keep a small flashlight in your glove box. It can help you locate the keyhole in low-light conditions, such as at night or in a dimly lit parking garage.

Alternative Methods to Unlock Your Subaru

If the manual key method doesn’t work—or if you’ve lost your key entirely—there are still several ways to unlock your Subaru.

Use Subaru StarLink Remote Services

If your Subaru is equipped with StarLink and you have an active subscription, you can use the StarLink app to remotely unlock your vehicle. This feature is available on most 2016 and newer models.

To use it, download the StarLink app on your smartphone, log in with your account, and select your vehicle. Tap the “Unlock” button, and the car will unlock within seconds—provided you have cellular coverage and the car is within range of a network.

This method is especially useful if you’ve locked your keys inside and don’t have the physical key. However, it requires an active subscription, which may cost $100–$200 per year.

Call Subaru Roadside Assistance

Subaru offers 24/7 roadside assistance to all owners, including help with lockouts. If you’re unable to unlock your car, call the Subaru Roadside Assistance number (1-800-782-8376 in the U.S.). A technician will come to your location and unlock the vehicle using specialized tools.

This service is free for the first year of ownership and may be included in extended warranties or service plans. It’s a reliable option if you’re in a bind and don’t want to risk damaging your car.

Contact a Professional Locksmith

If all else fails, a licensed automotive locksmith can help. They have the tools and expertise to unlock your Subaru without damaging the door or lock. Look for a locksmith who specializes in Subarus or modern vehicles with electronic locks.

Tip: Always verify the locksmith’s credentials and get a quote before they begin work. Avoid unlicensed or “mobile” locksmiths who may overcharge or use unsafe methods.

Preventing Future Lockouts

The best way to deal with a lockout is to avoid it altogether. Here are some practical tips to prevent locking your keys inside your Subaru.

Keep a Spare Key in a Secure Location

Store a spare key in a safe place, such as at home, with a trusted friend, or in a magnetic key box attached to the car’s undercarriage. Make sure the box is weatherproof and securely fastened.

Tip: Don’t hide the key in obvious places like under the mat or in the wheel well—thieves know these spots.

Use a Keychain Alarm or Tracker

Attach a Bluetooth tracker like Tile or Apple AirTag to your keychain. These devices can help you locate your keys if they’re misplaced. Some even send alerts if you leave your keys behind.

Alternatively, use a keychain alarm that sounds if the keys are separated from your phone by a certain distance.

Develop a Routine

Make it a habit to check for your keys before closing the car door. Say a quick phrase like “Keys, wallet, phone” to ensure you have everything. This simple routine can prevent most accidental lockouts.

Upgrade to Keyless Entry (If Not Already Equipped)

If you drive an older Subaru without keyless entry, consider upgrading to a system that allows you to unlock the car with a code or smartphone app. While this won’t eliminate the need for a physical key, it adds convenience and reduces the risk of lockouts.

Conclusion

Unlocking a Subaru with a key is easier than you might think. Thanks to the hidden physical key in most fobs, you’re never truly locked out. By following the steps in this guide—accessing the key, locating the keyhole, and turning it correctly—you can regain entry quickly and safely. And if the manual method doesn’t work, options like StarLink, roadside assistance, and locksmiths are there to help.

Remember, preparation is key. Keep your fob battery fresh, store a spare key, and develop habits that prevent lockouts. With these tips, you’ll be ready for anything—rain, snow, or a misplaced set of keys. Your Subaru is built to handle the road, and now you’re equipped to handle the unexpected.
