Quick answer: Gate remote not working? Start with the simplest fix and replace the battery in the remote. If a second remote also fails, the problem is at the gate, not the remote. Check that the motor has power, the motor battery isn’t flat, the safety beams are clear and the motor isn’t in manual or holiday mode. If none of that helps, the receiver may be faulty or damaged by a power surge, and a technician should test it.
You press the button and nothing happens. A gate remote that stops working is one of the most common calls our technicians get, and many of the causes take five minutes to fix. Work through the checks below in order, from the easiest to the most technical, before you book a callout.
First, find out if the problem is the remote or the gate
Try a second remote, or the keypad or intercom if your gate has one. The result tells you where to look:
- Only one remote fails: the problem is that remote. It may have a flat battery, be damaged or have been deleted from the receiver.
- All remotes fail, but the keypad or intercom still opens the gate: the motor is fine. The problem is the remote receiver or its memory.
- Nothing opens the gate: the problem is the motor, its power supply, its battery or the gate itself.
Gate remote troubleshooting at a glance
| What’s happening | Likely cause | What to try |
|---|---|---|
| The light on the remote is dim or doesn’t come on | Flat remote battery | Replace the battery |
| One remote works, another doesn’t | Faulty remote, or remote deleted from the receiver | New battery, then re-code or replace the remote |

| Everything stopped after a storm | Surge damage to the receiver or control card | Switch off at the isolator and call a technician |
Gate remote not working? 9 common causes and how to fix them
1. The remote battery is flat
This is the most common cause by far. Most remotes have a small light that comes on when you press a button. If it’s dim, flickers or doesn’t light at all, the battery is the problem. Most gate remotes use either a small 3V coin cell (such as a CR2032) or a 12V cylindrical battery (A23 or A27). The type is usually printed on the old battery, so take it with you to the shop.
If you have to press the button several times or stand closer to the gate than you used to, the battery is on its way out. Replace it before it leaves you stuck in the street.
2. The remote is damaged
Remotes live hard lives. They get dropped, sat on, left in hot cars and put through the wash. Worn buttons, water damage and cracked circuit boards all stop a remote from transmitting. If a new battery doesn’t help and your other remotes still work, the remote needs replacing. We supply and code replacement remotes for Centurion, Nice, Hansa and ET motors.
3. The remote has been deleted from the receiver
Every remote is stored in the receiver’s memory. A remote can be deleted when the receiver or control card is replaced, after a reset, or when someone clears the memory by mistake. If the remote’s light comes on but the gate ignores it, and other remotes still work, it probably needs to be coded in again. Also note that if the receiver’s memory is full, a new remote won’t save at all until old ones are removed.
4. The motor has no power or a flat battery
If the remote’s light works but nothing opens the gate, check the motor’s power. Make sure the isolator switch or plug next to the motor is on, and check your DB board for a tripped switch, especially after a storm. The battery inside the motor keeps the gate running during power cuts, but after long outages it can run flat. A weak battery can make the gate move slowly, stop halfway or ignore your remote completely. Read our guide on how long a gate motor battery lasts to see if yours is due for replacement.
5. The safety beams are blocked
Safety beams stop the gate from closing on a car, a child or a pet. If anything blocks them, the gate will open but refuse to close, which can look like a remote fault. Check for leaves, spider webs, overgrown plants, dirt on the lenses or a beam knocked out of line by wind or a garden hose. Wipe both lenses with a soft dry cloth and try again.
6. The motor is still in manual mode
If you’ve used the release key to open the gate by hand, for example during a power cut, the motor stays disengaged until you lock it back. You may hear the motor running while the gate stays still. Close the release, turn the key back and move the gate slightly by hand until the gears catch. Also check the track for stones, branches or anything else blocking the gate.
7. Holiday lockout is switched on
Some controllers have a holiday lockout or security mode that blocks remotes while you’re away. Depending on how your system was set up, it can be switched on from the controller, a keypad or a remote, sometimes by accident. If all your remotes stopped at the same moment and the motor has power, check your manual or ask us to check the settings.
8. Poor range or interference
If the remote only works when you’re right at the gate, the signal isn’t reaching the receiver properly. Common causes are a weak remote battery, a damaged or disconnected aerial on the receiver, metallised window tint on your car, or interference from other devices nearby. Start with a new battery. If the range is still poor, a technician can check the aerial and the receiver.
9. The receiver was damaged by a power surge
Summer storms are hard on gate electronics. A surge from a nearby lightning strike often damages the remote receiver, the control card or the battery charger, even when the motor itself survives. If your remotes stopped working after a storm, switch off the power at the isolator and don’t keep resetting the motor. Our guide to gate motor lightning damage explains the warning signs and how to protect your motor.
Can you code a new gate remote yourself?
Sometimes. Most receivers have a “learn” button, and the steps to add a remote differ between brands and models. Be careful, though: on some receivers, holding the learn button down for too long erases every remote in memory, which locks everyone out. If you don’t have the manual or you’re not sure which receiver you have, let a technician code it. It’s quick, and we test every remote before we leave.
Lost or stolen gate remote? Act quickly
A lost remote is a security risk, because whoever finds it can open your gate. Have it deleted from the receiver as soon as possible. Many receivers can remove a single remote, while others need the memory cleared and the remaining remotes coded in again.
If your system uses older fixed-code remotes, consider an upgrade. Fixed-code remotes send the same signal every time, which can be copied. Code-hopping (rolling code) remotes send a different code with every press, which makes them much harder to copy. If your remotes keep failing, an upgraded receiver often solves that problem too.
When to call a technician
Call us if:
- A new battery didn’t fix the remote and your other remotes don’t work either
- Nothing opens the gate, including the keypad or intercom
- The remotes stopped working after a storm or power surge
- The control card smells burnt or its status light is off
- You need remotes added, deleted or replaced
- The motor battery won’t hold a charge
Our technicians carry spares for Centurion, Nice, Hansa and ET motors, so most remote and receiver faults are fixed on the first visit. For other faults, see our guide to common gate motor problems and solutions.
Frequently asked questions
Why did my gate remote suddenly stop working?
The most common reason is a flat battery in the remote. If a new battery doesn’t help, check whether your other remotes work. If none of them do, the problem is at the gate, such as a power failure, a flat motor battery, blocked safety beams or a faulty receiver.
Can I code a new gate remote myself?
On many systems, yes, using the learn button on the receiver. The steps differ by brand, and on some receivers holding the button too long erases every remote. If you’re unsure, ask a technician to code it for you.
Why does my gate remote only work close to the gate?
Usually because the remote battery is weak. Other causes are a damaged receiver aerial, metallised window tint on your car and interference from nearby devices.
What should I do if I lose my gate remote?
Have it deleted from the receiver as soon as possible so that nobody else can use it. If you have older fixed-code remotes, it’s a good time to upgrade to code-hopping remotes, which are much harder to copy.
