Garage Door Cable Broke and Now It's Lopsided
First, take a breath—your door isn't ruined, and this is a very common, very fixable repair. When a lift cable snaps, that side of the door drops while the other side stays up, leaving it crooked and jammed in the track. Stop using the door immediately, leave it where it is, and don't try to force it up or down—a lopsided door means there's a lot of unbalanced weight (and possibly a wound-up spring) that can shift fast. This is a same-day repair for a pro, and cables should always be replaced in pairs.
Step by step
-
1
Stop and stay clear of the door
Don't hit the opener button and don't grab the door to muscle it level. A garage door weighs 130 to 350+ pounds, and with one cable gone that load is now hanging on one side. Keep kids and pets out of the garage, and don't park under or walk beneath a partially-open lopsided door—if the second cable or a spring lets go, things move with serious force.

Pull the red emergency release cord (only if you can do it safely)
If the door is stuck partway and the opener is straining, pull the red cord hanging from the opener trolley to disconnect the door from the motor. Important: only do this if the door is mostly closed or you can keep it from crashing down. If the door is up and looks like it could drop, leave the release alone and call a pro—disconnecting it could let the heavy side fall.

3
Don't park your car inside (or get it out now if it's already in there)
A lopsided door usually won't open or close fully, so you may be tempted to squeeze the car out. If the door is jammed in a stable position and your car is trapped, wait for the technician—it's not worth risking the door shifting onto your vehicle. If the door is safely propped and clearly stable, carefully move the car out so it's not blocked in during the repair.

Take a quick photo and look (don't touch) for the cause
Snap a picture of how the door is sitting and the loose cable—this helps the repair company quote accurately. From a safe distance, you'll usually see a frayed or snapped cable dangling near the bottom roller, often rusted at the bottom bracket where water collects. Do NOT touch the springs above the door or the cable drums—those hold tremendous tension.

Have both cables replaced as a pair
Cables wear at the same rate, so if one broke, the other is close behind. A reputable tech will replace both lift cables, re-wind them onto the drums, re-tension and balance the door, and check the springs and rollers while they're in there. Insist on both sides being done—skipping the 'good' one almost always means a second service call within months.
When to call a pro
Call a pro right away if the door is stuck open or only partly closed, if you see or hear the torsion spring involved, or anytime the cable drums, springs, or wound-up tension are in play—these are under enough force to cause serious injury and are not a DIY fix.

Is it safe to use my garage door with one broken cable?
No. With one cable broken, the door's weight is unbalanced and the remaining cable, spring, and hardware are under abnormal stress. Forcing it open or closed can snap the second cable, damage the door panels or track, or cause the door to slam down. Leave it as-is and have it serviced before using it again.
How much does it cost to fix a broken garage door cable?
Most cable replacements run roughly $130 to $300, depending on your area, whether one or both cables are done, and if rollers or springs need attention too. Replacing both cables as a pair is standard and the smart long-term call. A good company will give you an upfront, all-in price before starting.
Why did my garage door cable break in the first place?
The usual culprits are rust and moisture at the bottom bracket where the cable sits, normal wear over years of cycles, frayed strands rubbing on a misaligned drum, or a door that's been out of balance and putting extra strain on the cable. Hard, jerky travel or a door that wasn't moving smoothly often points to a problem that was building for a while.
Can I just fix the lopsided door myself?
We don't recommend it. Cable repairs require releasing and re-tensioning the system, and they sit right next to the springs, which store enough energy to cause severe injury if handled wrong. Unless you have the right tools and experience with garage door spring tension, this is a job for a trained technician—and it's usually a quick, affordable same-day fix.
