The Short Answer
Most gates that will not open are not broken — they have lost power, their backup battery has died, or the remote has quit. Before assuming the motor failed, check the outdoor GFCI outlet and the breaker, then try the keypad instead of the remote. Those two checks resolve a large share of these calls. If you need to get a vehicle out right now, every operator has a manual release that disconnects the motor so you can move the gate by hand.
Most Likely Causes, In Order
01
No power reaching the operator
The most common cause and the easiest to miss. Gate operators usually run off an outdoor GFCI outlet or a dedicated breaker, and both trip — especially after Houston thunderstorms. Find the outlet near the operator and press its reset button, then check your breaker panel. If the operator has a status light and it is dark, you have an electrical problem, not a gate problem.
02
Dead backup battery
Backup batteries last roughly three to five years in Texas heat, and a dying one causes genuinely strange behavior: the gate works in the morning and quits by afternoon, moves slowly, or stops halfway. If your battery is older than three years and the gate is behaving inconsistently, it is the prime suspect.
03
Remote battery dead or pairing lost
If the gate ignores the remote but responds to the keypad, the gate is fine. Remote coin batteries die roughly every two years. Less often, a remote loses its pairing after a power event and needs reprogramming.
04
Failed capacitor
The capacitor gives the motor its starting torque. When it weakens, you get a hum with no movement, or a gate that starts slowly and struggles. This is one of the most common genuine failures on operators past about year five, and it is an inexpensive part.
05
Manual release left disengaged
Worth checking and frequently overlooked. If someone used the manual release during a power outage and never re-engaged it, the motor runs but is no longer connected to the gate. You will hear the operator working while the gate sits still.
06
Control board failure
Boards die from lightning surges, water intrusion, and age. If there is power at the operator but no response from any input — remote, keypad, or the hard-wired button — the board is the likely culprit. This is a technician repair.
What You Can Safely Check Yourself
Run these in order before calling anyone. The first three resolve most cases and none of them require tools.
- ✓Press reset on the outdoor GFCI outlet near the operator
- ✓Check your breaker panel for a tripped breaker
- ✓Try the keypad instead of the remote — if the keypad works, it is a remote issue
- ✓Replace the coin battery in your remote
- ✓Confirm the manual release is engaged, not left disconnected from a previous outage
- ✓Listen when you press the button: a hum means power is reaching the motor, silence means it is not
How to Get Your Car Out Right Now
Every gate operator has a manual release — usually a key-operated pin or a lever that disconnects the motor so the gate moves by hand. Find it, release it, and push the gate open. If you do not know where yours is, look for a small keyed cover on the operator housing, and check the paperwork from your installation. Learn this before you need it: during hurricane season we walk people through their first-ever manual release over the phone, in the dark, sometimes with a medical appointment waiting. Practice it once on a calm day and tape a spare release key somewhere every family member can find it.
When to Stop and Call Someone
Call if there is confirmed power at the operator and still no response from any input, if you hear a hum but nothing moves, or if the gate moves only partway and stops. Those point to a capacitor, drive gear, or control board fault — all technician repairs, and all things that get worse if you keep pressing the button. Our $89 diagnostic covers the full system and is applied toward the repair.
Questions People Ask
Why won't my automatic gate open?
In order of likelihood: the GFCI outlet or breaker has tripped, the backup battery has died, the remote battery is dead, the capacitor has failed, or the manual release was left disengaged. Check power first and try the keypad instead of the remote, since those two steps identify the problem in most cases without any tools.
How do I open my gate manually when it has no power?
Use the manual release. Every operator has one, typically a key-operated pin or lever on the operator housing that disconnects the motor from the gate so you can push it open by hand. Once power returns, re-engage the release or the gate will not work under power.
My gate makes a humming noise but doesn't move. What does that mean?
Humming with no movement almost always means the motor is receiving power but cannot start under load. The usual cause is a failed capacitor. It can also mean a stripped drive gear or a gate that is physically jammed. Stop pressing the button, because running the motor in that state accelerates the damage.
Could a power outage have broken my gate?
It can, in two ways. Surges during an outage or when power is restored damage control boards, which is why we recommend killing power at the breaker before a storm. Separately, a multi-day outage drains a backup battery that may never fully recover if it was already old.
The gate worked this morning and not this afternoon. Why?
That intermittent pattern is the signature of a dying backup battery. It holds enough charge for the first few cycles of the day and then cannot deliver the current the motor needs. A battery older than three years that behaves this way should simply be replaced.
Do you service gates you did not install?
Yes. We service every brand found in Houston including LiftMaster, Viking, Apollo, Elite, All-O-Matic, DoorKing, and discontinued units. The $89 diagnostic covers any system regardless of who installed it.
