A loud, explosive bang from your garage on a Saturday morning usually means one thing: your garage door spring has snapped, trapping your car inside. It is a highly stressful, time-sensitive emergency. However, reacting in a panic can lead to severe physical injury, vehicle damage, or costly mechanical destruction. To navigate this situation safely and cost-effectively, you need a clear, professional protocol.

Before taking action, establish your immediate triage rules:
- Do NOT press the automatic opener button again. Automatic openers are only designed to lift 10 to 15 pounds of counterbalanced weight. Without the spring, the motor faces the full, unmitigated deadweight of the door, which can easily trigger a large electric garage door failure analysis scenario, stripping the drive gears instantly and adding $350 to $500 in motor replacement costs.
- Do NOT pull the red emergency cord if the door is partially open. Pulling the cord releases the trolley lock, immediately transferring 150 to 300+ pounds of deadweight to gravity. The door will crash down at terminal velocity like a guillotine.
- Do NOT attempt to replace the spring yourself. High-tension steel springs store lethal torque and should only be handled by certified professionals.
If your vehicle is trapped, your primary goal is to learn how to open garage door with broken spring safely using a controlled, physical extraction protocol.
