If your keys are locked inside your car, first check every door and the trunk, then try your spare key or your vehicle manufacturer’s mobile app if it supports remote unlocking. If those options do not work, contact roadside assistance or a reputable automotive locksmith. Avoid forcing the door or attempting risky entry methods that could damage the vehicle.

What to Do First When Your Keys Are Locked in the Car
Realizing that your keys are sitting inside a locked car can be frustrating, especially when you are in a hurry. The good news is that you usually have several safe options.
Start with the simplest solutions before doing anything to the vehicle.
Check Every Door and the Trunk
Take a moment to check all passenger doors, the driver’s door, the trunk, and any rear hatch. It sounds obvious, but one door may not have locked properly.
If the keys are visible through a window, resist the temptation to force the door open. Modern vehicles contain sensitive locks, electronics, airbags, weather seals, and other components that can become expensive to repair.
Look for a Spare Key
If you have a spare key at home, ask a family member or trusted friend to bring it to you. This is often the simplest and least expensive solution.
If your vehicle came with a physical emergency key inside the key fob, that key may also be useful—but only if you have the fob outside the vehicle.
Check Your Car’s Manufacturer App
Some newer vehicles have smartphone apps that provide remote functions, including door unlocking. Availability depends on the vehicle, its connected-services system, your account, and if the service is already activated.
If you have the manufacturer’s app installed, open it and look for a lock or unlock option. Do not assume every vehicle supports remote unlocking.
Can You Unlock the Car With Your Key Fob?
If you have the key fob with you but the car will not respond, the issue may be different from simply locking your keys inside.
For example, a weak or dead key-fob battery can prevent the remote buttons from working. Many modern fobs contain a hidden mechanical key for situations like this.
Check your owner’s manual for the correct procedure for your specific vehicle. The location and operation of the emergency key can vary between makes and models.
If the key fob is actually locked inside the vehicle, however, changing its battery will not solve the immediate lockout. You will still need another way to regain access.
Call Roadside Assistance
If the simple options do not work, roadside assistance is one of the safest choices.
Many roadside assistance plans include vehicle lockout service. AAA, for example, states that its roadside assistance includes 24-hour car lockout service, with coverage and reimbursement details depending on the membership level.
Your auto insurance policy may also include roadside assistance as an optional benefit. Check your insurance app, policy documents, or roadside assistance phone number before paying for a separate service.
When requesting help, be ready to provide:
- Your exact location
- Vehicle year, make, and model
- License plate information if requested
- if the key is inside the cabin or trunk
- if the key is lost, broken, or simply locked inside
- Any immediate safety concerns
A professional service may also ask for identification or information showing that you have the right to access the vehicle.
When to Call an Automotive Locksmith
An automotive locksmith can be a good option when roadside assistance is unavailable or when you need additional key-related services.
For example, a locksmith may help when:
- Your keys are locked inside the car.
- Your key is broken.
- You lost your car keys.
- You need a replacement key.
- Your key fob needs programming.
- The vehicle has a problem with its locking system.
AAA notes that automotive locksmith services can include vehicle entry, key cutting, key programming, and broken-key extraction, although these are separate services and coverage varies.
What to Tell the Locksmith
Be specific when you call.
Instead of simply saying, “I’m locked out,” explain if the key is inside the cabin, inside the trunk, broken in a lock, or completely lost.
Also provide the vehicle’s year, make, and model. Ask what the service will cost before agreeing to dispatch.
How to Avoid Locksmith Scams
Being locked out creates pressure, and scammers can take advantage of that urgency.
The Federal Trade Commission has advised consumers to research locksmiths, verify that they are legitimate, and get an estimate before work begins.
Be cautious if a company:
- Gives an unusually low starting price but will not explain the total cost.
- Refuses to identify the business clearly.
- Cannot provide a reasonable estimate before dispatch.
- Arrives with information that does not match the company you called.
- Pressures you into expensive work.
- Suddenly increases the praice after arriving.
Ask for the total expected cost, including service, labor, travel, and any after-hours charges. A 2026 consumer warning from Connecticut’s Department of Consumer Protection also recommends verifying the technician and getting a full estimate before work begins.
What If Your Keys Are Locked in the Trunk?
A trunk lockout can be more complicated because some vehicles do not allow the trunk to be opened independently when the vehicle is locked.
First, check if another door or hatch is unlocked. If not, look for a manufacturer app or another legitimate remote-access option.
If those options fail, contact roadside assistance or an automotive locksmith. Tell the provider that the keys are specifically in the trunk. This information can help the technician determine the appropriate service.
Do not try to force the trunk, pry the vehicle apart, or break a window simply because the keys are visible.
What Not to Do When Your Keys Are Locked Inside
You may find online instructions involving improvised tools or methods for bypassing vehicle locks. These approaches can be risky and can cause damage to the vehicle.
Avoid:
- Forcing a door open.
- Breaking a window when there is no immediate emergency.
- Prying against the door frame.
- Tampering with electronic locks.
- Cutting or damaging weather stripping.
- Using unfamiliar tools against the locking system.
A damaged door seal, window, lock, electrical component, or body panel can turn a simple lockout into a much more expensive repair.
Professional roadside technicians and automotive locksmiths have equipment designed for vehicle lockouts and can determine the appropriate way to regain access.
What If a Child or Pet Is Locked in the Car?
This is an emergency, not an ordinary lockout.
If a child is trapped inside a locked vehicle and may be in danger, call 911 immediately. NHTSA warns that vehicle interiors can become dangerously hot very quickly, even when the outside temperature does not seem extreme.
Do not wait for a locksmith or roadside technician if someone inside the vehicle is showing signs of distress or faces an immediate danger.
For a child alone in a locked vehicle, NHTSA specifically advises taking immediate action and calling 911.
How to Prevent Another Car Lockout
A few simple habits can reduce the chance of repeating the problem.
Keep a spare key: Store a spare somewhere secure and accessible to you or a trusted person.
Use a key routine: Put your keys in the same place whenever you arrive home.
Check before closing the door: Make it a habit to confirm that your key or fob is with you before shutting the vehicle.
Set up your manufacturer’s app: If your vehicle offers remote access, activate and test it before you actually need it.
Save roadside assistance information: Keep your insurance or roadside assistance number in your phone.
Know your key type: Learn if your vehicle uses a traditional key, transponder key, key fob, or smart key. This can make getting help much easier.
Frequently Asked Questions
Can AAA unlock a car if the keys are inside?
Yes. AAA offers vehicle lockout assistance for eligible members. Its current information says technicians can assist with locked-in keys, while coverage and locksmith reimbursement can vary by membership level and location.
Can a car app unlock my vehicle?
Some vehicles support remote unlocking through a manufacturer’s smartphone app. If this works depends on your vehicle, connected-services setup, account, and subscription or activation requirements. Check your manufacturer’s official app and owner’s manual.
What should I do if my keys are locked in the trunk?
Check every other door and hatch first. Then try a supported manufacturer app or contact roadside assistance or an automotive locksmith. Tell the provider that the key is in the trunk so they understand the exact lockout situation.
Should I call a locksmith or roadside assistance?
If you already have roadside assistance, it may be the easiest first choice because vehicle lockouts can be included in the service. A locksmith can be especially useful when you have lost a key, broken a key, or need key cutting or programming. Compare coverage before paying out of pocket.
Is it safe to try to open my car myself?
Simple checks, such as checking another door or using your spare key, are safe. However, forcing the door or experimenting with lock-bypass techniques can damage the vehicle. If the car remains locked, professional roadside assistance or an automotive locksmith is the safer option.
Conclusion
If your keys are locked inside your car, do not panic or start forcing the door. Check every door and the trunk, look for a spare key, and see if your vehicle supports remote unlocking through a manufacturer’s app. If those options fail, contact roadside assistance or a reputable automotive locksmith.
The safest solution is usually the one that gets you back inside without damaging your vehicle. If a child or vulnerable person is trapped inside, treat the situation as an emergency and call 911 immediately.
