How to use the manual release on a gate or door, safely
Mount Everest Automatic Doors team5 min readUpdated
Every automatic gate and door should have a way to move it by hand when the power fails or the motor stops. This guide explains the common kinds of release, how to approach using one safely and what to do afterwards. It is general guidance. The exact steps depend on your equipment, and the method shown at handover or in the maker's manual always takes priority.
Why it exists
A motor holds the gate or door in position. Without the release, a gate stuck shut after a power cut keeps you out, and a gate stuck open leaves a property exposed. A release lets you move the leaf by hand and so keeps access and exits available. It also lets a technician move the leaf during a repair.
The common kinds
- Key release on a swing gate operator. A small key unlocks a cover or a lever on the operator. Turning it disengages the arm so the leaf swings by hand.
- Lever or handle release on a sliding gate motor. A lever or knob on the motor, often behind a lockable cover, disengages the drive from the gate.
- Release cord or handle on a garage door opener. A cord with a handle hangs from the trolley on the rail. Pulling it disconnects the door from the opener.
- Manual override on rolling shutters. A chain, crank or hand wheel turns the barrel without the motor, or a key switch releases the brake.
- Mechanical release on barriers. Usually a key release that lets the arm be lifted or lowered.
- Release on automatic sliding doors. Many sliding doors can be pushed open by hand when the power is off, or have a release or a battery backup, depending on the model.
Your model may differ from this list. Ask us if you are unsure which kind you have.
Before you use it
- Check that it is a real power cut or a motor stop. If the motor is still running, wait until it stops. Do not release a moving gate.
- Clear people and vehicles from the path. Children and animals especially. A freed leaf has no motor to hold it, and on a slope it can run.
- Make sure you are not on a slope you cannot control. A gate on a sloping driveway may roll once released. If so, ask us how to chock or hold it.
- Find the key. If the release is locked, the key should be somewhere known and not locked inside the property.
Using the release
Follow the method shown at handover. In general, you disengage the drive, then move the leaf slowly by hand, keeping your body out of any pinch point such as the gap between the gate and a post. Move a garage door by lifting evenly from the centre of the bottom edge, only if the door feels balanced; if a spring has broken or the door feels very heavy, do not lift it. For a heavy rolling shutter, use the chain or crank as intended.
Do not force a leaf that does not move. A stiff gate can point to a jam, a broken part or an obstruction. Forcing can bend the gate or injure you.
Closing and securing
After passing through, move the leaf to the closed position and secure it. A gate released and left open is not secure. If you cannot lock a released gate, arrange for someone to stay, or contact us. Many properties have a secondary lock or a mechanical bolt for this.
Re-engaging
When power returns, or the technician has fixed the fault, re-engage the drive exactly as your handover showed. Often this means moving the leaf until the arm or carriage reconnects and locking the key or lever. Run one full cycle with the remote, watch for unusual movement and stop if there is any. Test that the gate or door still reverses on a soft obstacle.
Things not to do
- Do not use the release to defeat a safety fault and then keep using the gate in automatic mode.
- Do not release a garage door that is not fully supported by its springs.
- Do not stand under a door as you release it.
- Do not leave a released gate or door unattended where children play.
- Do not ignore a release that is stiff; rust or dust may have built up.
Practise it
Once a month, as part of your routine check, find the release and confirm you can operate it. Do it once with the power on at a quiet time, with someone watching, so you know how much effort it takes. Practising is also the best way to find a stuck or missing key.
Teach the household
Everyone who may need to use the gate in an emergency should know where the release is and the main rule: stop, clear, release slowly. Keep a note of our number near the control box.
When to call us
Call if the release will not disengage, if the gate or door moves too freely after release, if the key is lost, if the gate does not re-engage correctly or if you are in doubt at any stage. A quick photo of the motor and release helps us guide you.
Different equipment, same rule
A release for a rolling shutter, a barrier arm or a sliding glass door looks different from a gate release, but the rule is the same: stop the motor, clear the path, move the leaf slowly, secure it and re-engage with care. If your property has several kinds of equipment, ask us for a one-page note listing where each release is and how it works, and keep it with the other papers near the control box.
