Don't use a coat hanger
Modern door frames are not designed to be levered. A hanger forced past the weather seal typically bends the frame permanently, and on many vehicles it passes directly across the side-impact airbag sensor wiring.
Don't use a slim jim
Slim jims were designed for cars with mechanical linkage rods running down the door cavity. Modern doors pack that space with wiring looms, speakers and electric actuators. A slim jim in there is a lottery ticket you do not want to win.
Don't break the window as a first resort
A replacement side window plus glass removal from the door cavity and seat runners routinely exceeds $300 in Austin, TX. Professional entry costs a fraction of that and takes under ten minutes.
Don't wait if a child or pet is inside
Call 911 first, then call us. Interior temperatures in a closed vehicle in Central Texas climb dangerously within minutes. We escalate these calls to priority dispatch immediately and there is no shame in involving emergency services in parallel.
What to do instead
Move somewhere well lit and visible, note the exact address or the nearest cross street, and call a licensed mobile locksmith who will quote a firm price before dispatching. Most Austin, TX lockouts are resolved within thirty minutes of the first phone call.
