How to Trick Garage Door Sensors

If you have ever tried to get your garage door open when the sensors are blocked, you know that it is not easy. In fact, most people give up and find another way in. However, there is a way to trick the sensors into thinking nothing is blocking them. Keep reading to learn more about how to trick garage door sensors.

What Is a Garage Door Sensor?

A garage door sensor is a device that is mounted on the garage door and connected to the opener. The sensor detects when the door is open or closed and sends a signal to the opener to either open or close the door. The sensor is usually mounted on the side of the garage door near the bottom. It consists of two parts: a transmitter and a receiver.

The transmitter emits a beam of infrared light received by the receiver when the door is closed. However, the beam is interrupted when the door is opened, and the receiver does not receive a signal. This causes the opener to open or close the door.

Garage door sensors are an important safety feature because they prevent the door from closing if something is in the way. They are also used to detect when someone enters the garage so that the opener can be activated. Most garage doors have two sensors on each side of the door.

Why Should You Trick Garage Door Sensors?

Most garage doors have sensors that prevent the door from closing if something is in the way. However, these sensors can occasionally malfunction, preventing the door from closing even when nothing is in the way. If your garage door sensors are giving you trouble, there is a simple fix that you can try tricking the sensors.

Use a Magnet

This involves placing an object in front of one of the sensors and then moving it away before the door has a chance to close all the way. With the sensors tricked, you should be able to close your garage door and get on with your day.

So if your garage door sensors are acting up, don’t call a repairman just yet. Instead, try tricking the sensors first and see if that does the trick.

How to Trick Garage Door Sensors Step by Step Guide

Step 1: Inspect

You will need to look at the sensors and see how they are placed. For example, there may be a small red light when the door is closed. This means that there is an infrared beam between the two sensors.

Step 2: Cover One Sensor

The next step is to take an object and cover one of the garage door sensors. Once the sensor is covered, the door should begin to close. If it doesn’t, check to make sure that the other sensor isn’t obstructed.

If your garage door has sensors at its bottom, you can place a piece of tape or another object over the sensor. Unfortunately, doing this will trick the garage door into thinking that something is in the way and will try to close.

You can also use your hand to cover the sensor. But be sure not to keep your hand there for too long, or the door might close on it.

Cover One Sensor

Step 3: Wait for the Door to Close

Once you have covered one of the garage door sensors with your hand, quickly move your hand away and wait for the garage door to close. If you were successful, the garage door would close as usual despite an object in its path. Try this a few times to be sure that it works consistently. If it doesn’t work, make sure that you cover the sensor completely and try again.

Just be careful that you don’t place anything too large in front of the sensors, or the garage door won’t be able to close at all.

Step 4: Use a Magnet

If you want to be sure that your garage door will close, even if there is something in its path, you can use a magnet. Simply place the magnet on the side of the sensor (the side facing away from the door) and wait for the door to close.

The magnet will trick the sensor into thinking there is nothing in the way, and the door will close as usual. But, of course, if you don’t have a magnet, you can also use a piece of metal or even a paperclip. Just make sure that the object is small enough to fit between the sensor’s prongs.

Step 5: Use a Pen or Paper(Optional)

If you don’t have a magnet, you can also use a pen or a piece of paper. Just hold the pen or paper close to the sensor, and it should trick the sensor into thinking that there’s something there. You can also use a piece of aluminum foil if you don’t have a pen or paper handy.

Step 6: Remove the Object

After the door has closed, you will need to remove the object you placed in front of the sensor. For example, if you are using a piece of tape, simply peel it off and throw it away. You can leave it there if you use a magnet, paperclip, or other metal objects. The door will not be able to open again until the object is removed.

You have now successfully tricked your garage door sensors! This can come in handy if you ever need to close the door without anyone else being around or if you want to keep someone from opening the door. Remember to remove the object before you try to open the door again. Keep reading for more information about how to trick garage door sensors.

What Do Garage Door Sensors Do?

If you have a garage door, chances are it has sensors that help to keep it safe. But what do these sensors do, and how do they work? Garage door sensors are usually located at the bottom of the door, near the floor. They send out an infrared beam that bounces back off the floor.

If something breaks the beam (like a car or person), the sensor sends a signal to the opener, telling it to stop and reverse the door. This helps prevent accidents and injury, making your garage door safer for everyone. Garage door sensors are a vital part of any garage door system, and they can be a lifesaver.

Make sure to keep yours in good working order, and replace them if they become damaged. With proper care, your garage door will be safer and more reliable for years to come.

How Can I Bypass Garage Door Sensors Without Sensors?

Garage door sensors are an important safety feature, but they can also be a nuisance when they malfunction. If your garage door sensors are causing problems, there is a way to bypass them without replacing the sensors.

First, locate the sensors on the garage door opener unit. There are usually two sensors, one on each side of the unit. Next, use a small screwdriver to loosen the screws that hold the sensors in place. Once the screws are loosened, you can gently push the sensors out of the way. Be careful not to damage the wires.

Finally, re-tighten the screws and test the garage door opener to make sure it is working properly. Bypassing garage door sensors is a simple process that anyone can do. If you want to know more about how to trick garage door sensors, Keep reading.

How Do I Reset My Garage Door Sensors?

If your garage door isn’t opening or closing properly, the first thing you should check is the sensors. These simple devices play a vital role in ensuring the door operates safely, and they can often become misaligned or knocked out of position.

If this happens, resetting the sensors is usually a quick and easy fix. To do this, start by checking that both sensors are clean and free of obstructions. Then, use a level to check that they are mounted in the correct position. Finally, press the “Reset” button on the opener unit.

Once the lights on the sensors turn green, your door should be back to normal. If not, you may need to call a professional for further assistance.

Frequently Asked Question

Can You Bypass Garage Door Sensors?

The short answer is, unfortunately, no. You cannot bypass garage door sensors without triggering an alarm or breaking the system. The sensors are designed to detect any movement in the garage, so even if you get past one sensor, the others will still pick up on your presence and raise the alarm.

Does Sunlight Interfere with Garage Door Sensors?

Garage door sensors are designed to detect if an object is in the way of the garage door closing. If something is in the way, the sensor will send a signal to the garage door opener to stop the door from closing. Sunlight does not interfere with garage door sensors.

Which Material Should I Use for The Door?

There are a few different ways to trick your garage door sensors, depending on the type of sensor you have. For example, if you have an infrared sensor, you can try using a piece of black tape to block the sensor. This will cause the sensor to think there is no object in its path, and the door will open.
