Blinking sensor lights, a locked wall control, dead remote batteries — most "dead door" emergencies trace back to causes you can safely check in minutes. Here's the order to check them in.
Nothing is more frustrating — or more urgent — than a garage door that won't open when your car is locked inside. The good news: most "dead door" problems come down to a handful of causes you can safely check in minutes, without tools and without touching anything under tension.
Work through this checklist in order, from the most common and safest fixes to the ones that require a professional.
Dealing with a snapped cable or broken spring? Do NOT attempt to pull the red release cord while the door is open. Call our emergency techs at 713-9999161.
Every modern opener has two small sensors near the floor on either side of the door. They're the number-one cause of a door that closes halfway and reverses.
Many wall controls have a lock feature (a padlock icon) that disables all remotes. It's easy to press accidentally. If the wall button works but remotes don't, hold the lock button for a few seconds to toggle it off.
A remote that works only a few feet away — or only when pressed twice — is almost always a dying battery. Swap in a fresh one before assuming the opener is broken. Also check whether a second remote still works: if one works and the other doesn't, it's the remote, not the opener.
The red emergency release cord disconnects the door from the opener. If someone pulled it — or it was bumped — the opener will run while the door stays put.
A rock, a bent track, or debris in the roller path can stop the door cold. Look along both vertical tracks for anything obvious. Do not try to hammer out a bent track or force the door past an obstruction — that turns a small repair into panel and roller damage.
WARNING: If the door moves by hand but the opener hums and nothing happens, or the door is extremely heavy, stop. A broken spring, stripped gear, or off-track door needs a technician. Forcing the opener can destroy the motor and drop the door unexpectedly.
Call a licensed technician if: the door won't move manually, you hear grinding or bangs, the door is crooked or off its track, the opener hums without moving the door, or anything smells like burning plastic. These aren't DIY repairs — and a stuck open door is a security issue we treat as a priority.
That's almost always the safety sensors — blocked, misaligned, or dirty. Check the blinking lights first; it's the most common quick fix.
Probably not. Replace the remote battery, then check the wall control's lock feature. If a second remote works, the opener is fine.
Yes — but only when the door is fully closed, and only if it lifts smoothly. If it's heavy, crooked, or binds, the springs may be broken and manual operation is dangerous. Call for emergency service instead.
