Getting locked out of your car is frustrating and expensive. These 10 practical prevention tips — from key habits to tech solutions — help you avoid it for good.
A car lockout costs $75–$200 and an hour of your day. The good news: most lockouts are entirely preventable with a few simple habits and one-time setups. Here are 10 strategies that actually work — from free behavioral changes to small investments that pay for themselves the first time you use them.
1. Build a “Keys First” Habit
The most common cause of a car lockout: exiting the vehicle while the key is in the ignition or cup holder. Make it a rule — keys in hand before you open the door. This sounds obvious, but the habit has to be built consciously until it becomes automatic.
2. Keep a Spare Key — Not in the Car
Get a spare key cut today ($4–$25 for a mechanical key, $75–$250 if it’s a transponder). Give it to a trusted person who lives nearby — a family member, neighbor, or friend. This is free insurance for any lockout scenario.
Don’t keep the spare in the car (locked cars don’t help if you’re locked out) or under the bumper (thieves know to check magnetic key boxes in those spots).
3. Use a Magnetic Key Box — in a Smart Location
If you want a hidden spare on the vehicle, use a strong magnetic key box attached in a non-obvious location (not the bumper or under the fender flare). Options include inside the frame rails, behind a wheel well liner, or near the tow hitch. A key that’s hard to find for a casual thief but accessible to you in an emergency is worth having.
4. Enable Remote Unlock If Your Car Has It
Most cars built after 2010 offer remote unlock through the manufacturer’s connected services app (OnStar, Toyota Connected, Ford Pass, MyChevrolet, etc.). If you’re enrolled, you can unlock your car from anywhere with a smartphone — useful even if you left keys inside. Check if your vehicle subscription is active and set it up before you need it.
5. Attach a Bluetooth Tracker to Your Key Ring
Apple AirTag ($29), Tile Pro ($35), or similar Bluetooth trackers attach to a keyring and let you see your key’s location on your phone. This won’t help if the keys are inside a locked car, but it eliminates the panic of “I don’t know where my keys are” — which often leads to lockouts when someone makes a hasty second guess about where the keys are.
6. Use a Keypad or Smart Lock for Your Home, Extend the Mindset to Your Car
If you own a newer vehicle with a keypad entry (Ford has offered keypad door entry for decades), set up a code you’ll remember. Some aftermarket keypad systems are available for popular vehicles. It won’t help with ignition lockouts (keys left in running car) but resolves the most common door lockout scenario.
7. Never Leave a Running Car Unattended
“Warming up” your car in the driveway is the easiest path to a lockout (and a theft). If you must warm the car, stay with it or use a remote start system that can’t be driven without the key fob present.
8. Double-Check Before Closing the Trunk
Trunk lockouts happen when you set your keys down while loading groceries or luggage and close the trunk before picking them back up. Before closing the trunk: keys in hand. Every time.
9. Store a Roadside Assistance Number in Your Phone
Even with prevention, lockouts happen. Have (888) 351-2810 saved as “Locksmith Emergency” in your phone, or bookmark GotLocked. When you need a locksmith, you don’t want to be searching while stressed.
10. Check Your Roadside Assistance Coverage Now

Frequently Asked Questions — Car Lockout Prevention
Can a car lock itself with the keys inside?
Yes. This happens when the door is locked manually (or by a child accidentally hitting the door lock button) while the keys are inside, or when auto-lock features engage. Some modern vehicles won’t lock if the key fob is detected inside — check your owner’s manual for this setting.
What’s the cheapest way to get back into a locked car?
If you have roadside assistance through insurance, AAA, or a credit card, that’s typically free or very low cost. If not, a licensed mobile locksmith ($75–$150) is cheaper than prying the door yourself and risking damage to the weatherstripping or door lock mechanism (which can cost $200–$500 to repair).
How do car manufacturers prevent lockouts on new models?
Most modern vehicles with key fob systems won’t lock if the fob is detected inside the cabin. Proximity sensors in the door handles can unlock the car if the fob is nearby. Backup digital keys (via manufacturer apps) add another layer. However, edge cases still happen — dead fob battery, sensor failure, accidental manual lock.
