> **Quick Answer:** A dead battery cuts power to your electric door locks. Every car with power locks also has a manual override. Check the door panel for a physical lock tab or pull lever near the window. If you're in the cabin, try the interior door handle while lifting or pressing the manual lock. If you're outside, use your physical key in the door cylinder. You are not trapped.

## What To Do
**If you're inside the car:**
1. Look at the top edge of the door panel, near the window. Most vehicles have a small plastic tab, toggle, or pull lever. That is the manual lock. Flip it, slide it, or pull it depending on your car. Then pull the interior door handle normally.
2. If you do not see a tab, check the door panel armrest area. Some vehicles hide the manual lock release under a small plastic cap. Pop it off with a coin or fingernail.
3. On older vehicles, the manual lock is the knob that sticks up from the top of the door panel at the window base. Pull it up, then open the door.
4. Child safety locks engaged on rear doors? You cannot override those from inside. Move to a front door or window.
5. If a door will not open at all and you are in a non-emergency situation, lower a window manually if your car has hand cranks. If windows are also electric and fully dead, move to the trunk release. Most sedans have a fold-down rear seat or a glow-in-the-dark emergency release tab inside the trunk itself.
**If you're locked outside the car:**
1. Use your physical key in the door lock cylinder. This works even with a completely dead battery. Every car sold in the United States is required to have a mechanical key cylinder. If your key fob has a hidden metal key inside, pull it out now. There is usually a small release button or tab on the fob.
2. Insert the key, turn it, open the door. The power locks being dead does not affect the cylinder.
3. Once inside, do not try to start the car yet. Address the battery first.
**After you get the door open:**
Jump-starting is the fastest fix if you have cables or a portable jump starter. [If your car won't start even after a jump attempt, there may be more going on than just the battery.](/car-wont-start-but-has-power-dashboard-lights-on/) A clicking noise when you turn the key usually means the battery is fully discharged or the starter is failing. [A single clicking or rapid clicking noise on startup points to a specific problem worth diagnosing before you call a tow.](/car-wont-start-clicking-noise-need-tow-truck-cost/)
If the car will not start after a jump, you need a tow.

## What It Might Cost
- **Jump start from roadside assistance:** $0 if covered by insurance or AAA, $50 to $100 out of pocket
- **Locksmith if key cylinder is damaged or you have no key:** $75 to $150
- **Tow to a shop if battery or electrical system is the deeper problem:** $75 to $175 for a local tow, more in high-cost cities
Check your insurance app before calling a private service. Many auto policies include roadside assistance that covers battery jumps and lockouts at no added cost per incident. [Knowing what your policy covers before you are stranded makes a real difference in what you pay.](/car-insurance-deductible-applies-to-towing-cost/)

## Stay Safe
- If you are inside a hot car, especially with a child or pet, break a window. Do not wait. Use your elbow, a headrest rod, or a hard object aimed at a corner of the glass.
- If you are stranded in traffic or an unsafe location and cannot exit the vehicle, call 911. Tell them your location and that you are unable to exit.
- Do not prop the hood open and walk away from the vehicle on a highway. Stay behind the guardrail if possible. [If your car died on a highway shoulder, read this before deciding where to stand.](/car-died-on-highway-shoulder-safe-to-wait-for-tow/)
- Hazard lights may not work with a fully dead battery. If it is dark, use your phone flashlight to signal approaching vehicles.
- Never run jumper cables while leaning over both batteries at the same time. Connect positive to positive, then negative to an unpainted metal ground on the dead car, away from the battery.
