How to Unlock a BMW With the Keys Locked Inside

Locked your keys inside your BMW? Don’t panic—it happens to the best of us. Whether your key fob slipped off the seat or the car auto-locked on its own, there are safe and effective ways to unlock your BMW without causing damage.

This guide walks you through several proven methods to regain access to your locked BMW quickly.

Can You Unlock a BMW if the Keys Are Inside?

Yes, it’s possible to unlock a BMW with the keys inside using the spare key, manual key blade, or roadside assistance services. Some models even prevent locking when the fob is detected inside—but not all.

Your best option depends on your BMW model, available tools, and how quickly you need access. Let’s explore each method.

1. Use the Spare Key Fob

If you have a spare key fob, use it to unlock the doors remotely. This is the easiest and safest way to get back into your BMW.

Keep your spare key in a safe place at home or with a trusted friend or family member for emergencies like this.

2. Use the Manual Key Blade

All BMW key fobs come with a hidden metal blade that lets you unlock the driver’s door manually.

Here’s how to use it:

1. Slide the small release tab on the back of the key fob.
2. Pull out the manual key blade.
3. Look for the keyhole on the driver’s door handle—it may be covered.
4. Gently pry off the plastic cover to reveal the lock cylinder.
5. Insert the key blade and turn to unlock the door.

Once inside, place the key fob near the steering column to start the engine, even if the fob battery is dead.

3. Call BMW Roadside Assistance

If you don’t have a spare key or can’t access the manual blade, BMW Roadside Assistance can help unlock your car professionally.

Steps to follow:

1. Call BMW Roadside Assistance (number should be on your key card or owner’s manual).
2. Give them your VIN, location, and proof of ownership.
3. A technician will be dispatched to unlock your car safely.

This service is often free for newer BMWs still under warranty or covered by BMW Assist.

4. Use a Smartphone App (For Equipped Models)

If your BMW supports BMW ConnectedDrive and you’ve activated the app, you may be able to unlock your car remotely from your phone.

Steps:

1. Open the My BMW app on your phone.
2. Go to the “Vehicle” section.
3. Select “Remote Services” and choose “Unlock Vehicle.”

This only works if your BMW is online, the app is set up, and remote services are active. It’s a lifesaver if you’ve locked the key inside and your phone is still with you.

5. Contact a Professional Auto Locksmith

Trained locksmiths can unlock modern BMWs without damaging the car, even with advanced keyless entry systems.

If you don’t have BMW roadside coverage or the app isn’t set up, this is a reliable third-party option.

Before calling a locksmith:

• Make sure they’re certified and experienced with European vehicles.
• Request a quote before they come out.
• Have your vehicle registration and ID ready to prove ownership.

6. Avoid DIY Unlocking Methods

Trying to pry open a door or use a coat hanger can easily damage your BMW’s paint, trim, or locking system.

Modern BMWs are designed to resist forced entry. Trying to break in yourself could cause more problems—like a broken window, tripped alarm, or disabled electronics.

Stick with the safe options: spare key, manual blade, roadside service, or app.

Will BMW Lock With the Key Fob Inside?

Some BMW models have a safety feature that prevents auto-locking if the key fob is detected inside. But this doesn’t always work:

• Key might be out of range (e.g., in trunk or far corner of the cabin)
• Key fob battery may be weak
• Comfort Access may be disabled

If the car doesn’t detect the fob as “inside,” it can still lock the doors—even with the key in the vehicle.

Tips to Avoid Locking Keys Inside a BMW

Here are a few simple ways to prevent this problem in the future:

• Always take your key fob with you, even when refueling or stopping briefly.
• Don’t leave the fob in the trunk or on a seat.
• Keep a spare key at home or in a lockbox outside the vehicle.
• Use the My BMW app to monitor and control your vehicle remotely.

These habits can save you from getting locked out unexpectedly.
