Cable imbalance failure
Either it frays where it wraps the drum until a few strands give out and the door starts to hang crooked, or it snaps clean, usually on the side that's been carrying the imbalance from a spring that's already going soft.
Keller, Coppell
Snapped or frayed garage door cables on Keller, TX homes get fixed by Coppell Garage Door Co, 14 miles out, on torsion setups typical of houses built after 1999.

Booking
We run this job out to Keller from Coppell, about 14 miles down the road, so a cable call here isn't a same-block errand for us - it's a scheduled trip, and we tell you that up front rather than promise something we can't back up. Call and describe what you're seeing: a door that dropped on one side, a cable hanging loose off the drum, or a snap you heard from inside the house. That tells us whether we're bringing a standard extension cable set or torsion-side gear. We don't quote a repair over the phone without knowing the door's age and spring type, because a house built in 1999 and one built in 2010 in this area can carry different hardware even on the same street. Have your garage door opener model or door brand handy if you know it - it saves a trip back to the truck once we're already in your driveway. See [near Keller](/near/keller/) for the towns we cover on this same run.
Watch-outs
A garage door cable does one job - it pulls the door up when the springs release their tension - and when it goes, it usually goes one of two ways.
Either it frays where it wraps the drum until a few strands give out and the door starts to hang crooked, or it snaps clean, usually on the side that's been carrying the imbalance from a spring that's already going soft.
On a two-car door, one cable failing means the door doesn't lift straight - it cocks sideways in the track and can jump the roller. On single doors it's more likely to just stop moving.
Either way, the door is not safe to run through the opener until the cable is replaced, because the drum can keep spinning and dump the whole door on its track guides.
Local causes
Keller's housing stock runs newer than a lot of what we cover out of Coppell - the area-wide median build year lands around 1999, and Keller's own numbers track close to that. That matters for cable repair because houses from this era were mostly built with torsion spring systems rather than the older side-mount extension setups you'd find on 1970s construction. Torsion cables sit under different load and wear differently - they fail from cyclic fatigue at the drum wrap point rather than from rust or a snapped end hook. At a median household income of $172,654, a lot of these are two-car doors carrying heavier insulated panels, which puts more static load on the cable and drum than a lighter single door. That's the failure pattern we plan for before we ever get in the truck for a Keller call, not the one you'd plan for on an older street.
On the truck
For a torsion setup - the majority of what we see on Keller doors given the 1999-era build pattern - we carry galvanized aircraft cable in the standard drum diameters, plus spare drums themselves, since a cable that's frayed at the wrap often means the drum groove is chewed up too and needs replacing alongside it. We also stock winding bars, a tension gauge, and the clamps for a proper cable-to-bracket termination - cable repair without the right clamp is a callback waiting to happen. What we don't carry as standard stock is every specialty low-headroom torsion kit; if your door has an unusual headroom clearance, we may need to order that part, and we'll tell you that on-site rather than pretend otherwise. That's the one honest gap in what rides on the truck every day.
Our process
First we release spring tension safely - winding bars, not shortcuts - before anything touches the cable, because a loaded torsion spring is the actual danger here, not the cable itself.
Then we pull the old cable and inspect the drum groove for wear; if it's cut a channel from the frayed strands, the drum gets replaced along with the cable, not just patched around.
New cable goes on, seated correctly in the drum, tensioned to match the door's weight and spring rating, then we re-wind the spring to factory turns for that door size.
Last step is running the door through a full open-close cycle by hand before we ever let the opener touch it, checking for drift, drag, or an uneven pull on either side. If the door's out of balance after the cable's replaced, that points to a spring problem underneath it, and we'll say so rather than call the job done.
Warning signs
Most Keller calls start the same way: the door lifts unevenly, hangs a few inches lower on one side, or stalls partway up with the opener straining against it. Some owners hear the snap directly - a sharp pop from the garage followed by the door refusing to move. Others just notice the door's been getting a little crooked for a week before it finally lets go, which is usually the fraying case rather than the clean break. If your door drops fast and hard when you try to open it manually, stop - that's a loaded spring with a failed cable, and it's not a DIY fix.

Questions
Yes. Keller's housing runs mostly torsion-spring era, built around 1999 on median, so most doors here use torsion-side cables and drums rather than the older side-mount extension cables you'd find on 1970s construction. The failure pattern and the parts we bring differ accordingly.
Don't run it through the opener. A broken cable on one side means the drum can spin free and drop the door unevenly onto its track. Leave the door where it is, disconnect the opener if you can reach the release, and wait for the tech.
Only when the drum groove is worn or cut from the frayed cable strands. If the drum's still clean, we reuse it and just replace the cable and clamp. We check it on-site rather than replace parts that don't need it.
About 14 miles. We schedule Keller cable calls as a dedicated trip rather than a same-hour drop-in, so it helps to describe the problem clearly when you call so we bring the right cable and drum stock the first time.
