Springs do nearly all the lifting. A standard residential door weighs 130 to 300+ pounds, and the springs counterbalance almost all of it — that’s why a healthy door feels light enough to lift with one hand. With a broken spring, you’re lifting the full weight yourself, with no counterbalance and no safety margin. If your grip slips, that weight comes down fast, and it can seriously injure hands, arms, or anything underneath.

If you absolutely must get the door open once — say, to get your car out — here’s the safest way. First, disconnect the opener by pulling the red emergency release cord; never try this with the opener engaged, or the motor will fight you and can be damaged. Second, get help: this is a two-person job. One person alone cannot safely control a dead-weight door.

Third, both people lift together from the bottom of the door, keeping backs straight and lifting with legs. Raise it slowly and steadily — no jerking. Fourth, once the door is fully open, clamp locking pliers onto the track just below the bottom roller on both sides. This is critical: without the clamp, the door can crash back down. Only then should anyone walk under it or drive out.

• Disconnect the opener first — pull the red release cord.
• Use two people; never attempt a heavy door alone.
• Lift slowly and evenly from the bottom of the door.
• Clamp locking pliers on both tracks below the rollers before going under.
• Keep children and pets far away during the entire process.

Don’t attempt this if the door is a heavy wooden or insulated double door — some weigh over 300 pounds, beyond what two people can safely control. Don’t try it if the door is off its track, hanging crooked, or if cables are visibly loose or tangled — in those cases the door can shift sideways and fall out of the tracks entirely. And don’t try it if you have any back, shoulder, or grip issues. No car trip is worth an injury.

Here’s the part people forget: after you drive out, you still have an open garage with a broken spring. Lowering a dead-weight door is just as hazardous as lifting it — it wants to slam. The same two-person technique applies in reverse: both people guide it down slowly and steadily, keeping hands clear of the sections as they fold. Once closed, disconnect concerns end — but don’t use the opener until the spring is replaced, or you’ll burn out the motor.

Manually operating a broken-spring door is an emergency workaround, not a solution. Every manual cycle risks injury and risks damaging the tracks, rollers, and opener. A professional spring replacement is typically a same-visit job taking under an hour, and it restores the door to safe, one-handed operation immediately. If your spring broke today, the safest thing you can do is leave the door alone and call for service.

A safety cable (also called a containment cable) is a simple steel cable threaded through the center of each extension spring and anchored to the wall bracket at one end and the track at the other. Under normal operation, it does nothing at all — it just sits there. Its entire job happens in the fraction of a second when a spring breaks: instead of flying across the garage, the broken spring stays threaded on the cable, hanging harmlessly in place.

It’s a humble part — essentially a length of aircraft-grade cable with a couple of clips — but it’s the difference between a broken spring being an inconvenience and a broken spring being a hazard.

Many older garage doors were installed without safety cables, back when they weren’t standard practice. Here’s how to check: with the door closed, look at the extension springs running along the horizontal tracks above the door. You should see a cable running through the middle of each spring, from the front of the track to a bracket at the back wall. If you look through the spring and see daylight — no cable — your door doesn’t have them.

No safety cables doesn’t mean your door is about to fail, but it does mean a future spring break will be more dangerous than it needs to be. Adding safety cables is a quick, inexpensive upgrade that any garage door technician can do, and it’s often done during a routine maintenance visit.

• Fraying or rust: run your eyes along the cable — frayed strands or heavy rust mean it’s weakened.
• Slack or sagging: the cable should run fairly straight through the spring; excessive slack means it’s not anchored correctly.
• Missing clips or loose anchors: check where the cable attaches at each end — loose hardware defeats the purpose.
• No cable at all: the most common issue on older doors; worth adding.

You might wonder why torsion springs — the coils above the door — don’t need safety cables. The answer is geometry: a torsion spring is wound around a solid steel shaft, so when it breaks, the shaft itself contains the pieces. Extension springs have nothing running through them, which is why they need the added cable. If your door uses torsion springs, safety cables aren’t part of the equation; if it uses extension springs, they’re essential.

Safety cables are not the same as the door’s lifting cables — the cables attached to the bottom corners of the door that wind onto drums when the door opens. Lifting cables do active work every cycle; safety cables are purely a failsafe. Both should be inspected, but they serve completely different purposes. (For more on lifting cables, see our guide to garage door cable types.)
