What to do if you've locked your keys in your car?

If you've locked your keys in your car, first check all doors and the trunk, then try a spare key or a manufacturer's smartphone app. If unsuccessful, your main solutions are calling a professional locksmith or roadside assistance, with costs typically ranging from $75 to $150. In non-emergencies, police usually cannot help. The fastest resolution often involves using a telematics service like OnStar if your vehicle is equipped, or a local locksmith for on-the-spot service.

Begin by systematically checking every door, including the trunk or hatchback. It's not uncommon for one latch to fail to engage fully. Next, recall if you have a spare key accessible. This could be with a family member, at your office, or in a magnetic key holder secured discreetly on the vehicle's frame. For modern vehicles, check if the manufacturer's app (e.g., MyChevrolet, Toyota App, FordPass, Tesla app) offers a remote unlock function. This is often the quickest and most cost-effective solution if available.

If no spare or app is an option, your next call should be to a professional automotive locksmith or your roadside assistance provider. A reputable locksmith can usually arrive within 30 minutes and use specialized non-damage tools like an air wedge and long reach rod to manipulate the interior lock button. The average cost for this service is between $75 and $150, depending on your location, the time of day, and the vehicle's make and model. Roadside assistance through clubs like AAA or your auto insurance policy may cover this service for free or at a reduced rate, but wait times can be longer during peak hours.

Contacting the police is generally reserved for true emergencies where there is an immediate danger, such as a child, pet, or essential medication locked inside in extreme weather. Most police departments no longer respond to simple lockouts due to liability and resource constraints.

To prevent future incidents, consider these proven strategies. Keep a traditional, non-electronic spare key in your wallet or purse; it's thin and reliable. For a spare electronic fob, a magnetic lockbox attached to the vehicle's frame is a common solution, though be aware of the security trade-off. Some drivers use a faraday bag/pouch to block signals and consistently store their key fob inside, preventing passive locking mechanisms from engaging when the fob is left in the car.

Happened to me last month at the grocery store. Panic first, then logic. I walked around, jiggling every door handle—no luck. My spouse was an hour away with the spare. I called a locksmith from a quick web search. He was there in 20 minutes, used a little airbag thing to pry the door open a crack, and fished the lock up with a rod. Cost me $90 on the spot. Lesson learned? I ordered a magnetic key box for under the wheel well that weekend. It’s peace of mind.

As a locksmith with over 15 years of experience, I see this daily. The first thing I ask customers is, "Did you check the trunk?" You'd be surprised. For modern cars with keyless entry, the problem is often a dead fob battery causing the doors to lock automatically. My advice: know your resources. If you have OnStar, use it. If you have AAA, call them. If not, a local locksmith is your best bet. We have vehicle-specific tools to open 99% of cars without a scratch. The price isn't arbitrary; complex European models or trucks with vertical lock rods simply take more skill and time. A fair price for a standard sedan is $80-$120.

Never try the coat hanger trick yourself on a modern car. You'll likely cost yourself a $300 window regulator or door seal repair. That's the real expense.

Prevention is way easier than the cure. I keep a plain metal key—the one that slides out of my fob—in my wallet. It doesn't help start the car (needs the chip for that), but it will absolutely open the driver's door. That's my emergency backup.

I also use a habit: the "key in hand" rule before shutting any door. And I've disabled the auto-lock feature on my car because I once threw my keys on the passenger seat and the car locked itself as I walked away. Check your manual; you can often turn that "feature" off.

For families, have a designated spare key location at home that everyone knows, and make sure a trusted neighbor has access.

The digital approach is changing the game, but it has its own pitfalls. My car has a phone-as-a-key feature. I locked my phone inside once—ironic, right? Thankfully, I could use my smartwatch to call a friend who had the app and could unlock it for me remotely. That's a pro-tip: ensure your car's connected services app allows for shared access with a family member.

However, reliance on apps requires a data connection and a charged phone. What if you're in a rural area with no service? The physical spare key is still the ultimate failsafe. The future is in biometrics or ultra-wideband tech that prevents locking with the key inside, but until that's standard, a layered strategy works best. Use the tech, but back it up with a physical plan. Know what your car's capabilities are before you're stuck in a parking lot.
