Quick Answer: You have a key locked inside with the engine running. Call a locksmith first ($50-150), not a tow truck. If locksmith can’t help, towing costs $75-200 locally. Turn off engine remotely if possible to prevent overheating or theft.
What To Do Right Now
Check your phone for remote engine shutdown. Many newer cars let you turn off the engine through manufacturer apps like OnStar, Toyota Connect, or BMW ConnectedDrive. This buys you time and eliminates the theft and overheating risk while you wait for help. If your car is a 2018 or newer model, there is a reasonable chance this feature exists even if you have never set it up. Check the app store now.
Call a locksmith, not a tow truck. Locksmiths cost $50-150 and arrive faster than tow trucks. They can unlock your car without moving it. A skilled locksmith can open most standard door locks in under 10 minutes using a slim jim or air wedge kit, with zero damage to your vehicle.
If you have roadside assistance, call them first. GEICO roadside assistance covers lockout service up to your plan limits, usually $50-100 per incident. Have your policy number ready and ask specifically whether the lockout service includes a running-engine situation, since some plans treat it as a higher-priority call.
Look for unlocked windows or doors. Check every window and door, including the trunk release if accessible from outside. Hatchbacks sometimes have a rear latch that can be triggered without a key. A cracked window of even 2-3 inches may allow a locksmith to insert a reach tool and pull the interior handle directly.
Only call a tow truck if the locksmith fails. Some older cars or high-security systems require dealer programming, making towing to the dealership necessary.
Stay with your vehicle. A running car attracts thieves and police attention. Never leave it unattended. If you are in an unsafe area, stand near a business entrance where you are visible and in a crowd, but keep the car in your line of sight.

When You Need Towing Instead
Some situations require towing over locksmith service:
- Luxury cars with advanced security. BMW, Mercedes, and Audi often need dealer reprogramming after lockout attempts. Forcing these locks can trigger a full security lockdown that disables the ignition entirely.
- Push-button start vehicles. These systems sometimes require computer reset at the dealership. The key fob communicates with the car via encrypted signal, and some models will not release the transmission lock or allow manual override without a dealer scan tool.
- Locksmith damage concerns. If you’re worried about window or door frame damage, towing to the dealership costs $75-200 but protects your car. This matters most on leased vehicles where body damage comes out of your deposit.
- Failed locksmith attempts. After 2-3 attempts, the car’s security system may lock down completely. At that point, towing is the only option that does not risk deeper electrical problems.
- Engine running over 30 minutes in heat. If the temperature outside is above 90 degrees and the car has been idling without airflow for an extended period, overheating becomes a real risk. A running engine in a closed garage is an immediate emergency requiring the fire department, not a locksmith.
What It Costs
Locksmith service: $50-150 for standard vehicles, $100-200 for luxury cars with advanced locks. After-hours or weekend calls typically add a $25-50 service fee on top of the base rate.
Towing to dealership: $75-200 for local distances under 10 miles. Expect $3-7 per additional mile. If the dealership is more than 20 miles away, budget at least $150-250 before any diagnostic fees.
Dealership lockout service: $150-300 including reprogramming if needed. Some dealers charge a flat diagnostic fee of $100-150 just to connect a scan tool, separate from any actual repair cost.
Insurance coverage: Most roadside assistance covers lockout service. Progressive insurance towing coverage includes lockout help, but check your specific limits. Coverage that caps at $50 will not fully offset a luxury-car locksmith bill.

Common Questions
Q: Will the engine overheat if I leave it running while I wait for a locksmith? A: In most cases, no. A running engine with a functioning cooling system can idle for 30-60 minutes without overheating, even in warm weather. Watch for the temperature gauge climbing toward the red zone or steam from the hood, and call the fire department immediately if either happens.
Q: Can a locksmith open my car without damaging the door or window seals? A: Yes, on most vehicles. Professional locksmiths use air wedge kits and long-reach tools that slip through the door gap without bending frames or tearing seals. The risk of damage goes up significantly on newer luxury vehicles with tighter tolerances, which is one reason towing to the dealer is sometimes the smarter call.
Q: My car has a keypad entry on the door. Can I use that to get in even with the key locked inside? A: Yes, if you remember the factory code or your personal code. Ford vehicles, for example, have a factory keypad code printed on a sticker inside the driver’s door jamb, and many owners store it in their phone contacts for exactly this situation. Check your owner’s manual for the code location specific to your model.
