Several methods can be utilized to circumvent a garage door sensor, including using tape, a laser, a reflector, or by simply triggering the garage door opener.
Should you discover that your garage door is malfunctioning, there are numerous reasons for significant concern.
However, in some situations, you might need to learn how to bypass the garage door sensors. In this post, I’ll explain how. So, keep reading!

Types of Garage Door Sensors
Photoelectric Sensors (or Photo Eyes)
- Photoelectric sensors are the most common type of garage door sensors used in modern residential garage door systems.
- They consist of two units, typically placed on each side of the garage door near the bottom of the door tracks.
- Each unit contains an infrared light source and a receiver.
- When the garage door is closing, the infrared light beam is emitted from one unit to the other, forming an invisible beam across the garage door opening.
- If anything disrupts the beam while the garage door is closing, the beam is broken, and the sensor immediately detects this change.
- When the sensor detects the interrupted beam, it sends a signal to the garage door opener, instructing it to stop closing and reverse the door’s movement.
- This reversal prevents the garage door from closing on the obstruction and ensures the safety of anyone or anything in the door’s path.
Pressure (or Contact) Sensors
- Pressure sensors are an alternative garage door safety sensor type, but they are less commonly used than photoelectric sensors.
- These sensors are often installed along the bottom edge of the garage door, inside the garage.
- Pressure sensors are designed to detect physical resistance or pressure when the garage door comes into contact with an object or obstruction while closing.
- When the pressure sensor senses an increase in resistance, indicating an obstruction, it sends a signal to the garage door opener to reverse the door’s movement.
- Like photoelectric sensors, this prevents the garage door from causing harm to anything in its path.

How does a garage door sensor work?
The garage door sensor works through an infrared radio signal that enables the electric motor when you press the button on a garage door remote.
As a result, the electric motor utilizes a track-and-pulley system that opens and closes the garage door. In addition, infrared sensors are installed on the garage door/doors approximately six feet inches off the ground.
Moreover, some buttons on the garage door sensor are wired to your house or remotely so that you can still activate them while inside the car or when located at other portions of the house.
However, the most sophisticated and recent garage door sensors use both technologies for the sake of convenience.

How do you turn off the motion sensor on a garage door opener?
Here are ways to turn off the motion sensor on a garage door opener:
- Set the door to manual mode. Pull down the manual release cord to disable the automatic opening system.
- Disconnect garage door sensors. Locate the sensors on the garage doors and disconnect them. Use a cutter to cut the wires from the sensor.

Why is my garage door motion sensor not working?
Here are some reasons why the garage door motion isn’t working:
- dirty sensor lenses
- moisture exposure
- poor sensor alignment
- old sensors
- power supply issues
- objects obstructing the sensor path
- LED lights not working
How do you fix an automatic garage door sensor?
Here are ways to fix an automatic garage door sensor that’s not working:
- Remove the objects blocking the sensors.
- Check for loose or broken connections.
- Clean the sensor lenses with a soft cloth.
- Make sure sensors are properly aligned on both doors.
- If there is a problem with moisture, make sure to dry it by opening the garage door.
Garage Door Sensor Insights
- Garage door sensors are vital to any smart home security system, providing real-time alerts if your garage door is left open unexpectedly.
- They can also be integrated with other smart home devices, like lights or cameras, to trigger automated actions when the door opens or closes.
- While typically connected to a central hub, some garage door sensors can function independently, sending smartphone notifications directly.

FAQs
Are garage door sensors necessary?
Yes, garage door sensors are essential for safety. They are required by law in most places to ensure that garage doors do not cause harm to people or property.
How often should I test my garage door sensors?
It is recommended to test your garage door sensors at least once a month. Regular testing ensures they are functioning correctly and can prevent accidents.
What should I do if my garage door sensors are not working correctly?
If you notice any issues with your garage door sensors, such as false alarms or failure to detect obstructions, consult a professional garage door technician for inspection and repairs.
Conclusion
Bypassing the garage door sensor means deactivating its automatic open system, allowing you to close and open the garage door manually.
There are several ways to bypass the garage door sensor, as explained in this article. However, make sure to activate the sensors afterward for security purposes.
