Can You Bypass Garage Door Sensors? How to Disconnect, Fix, or Disable Them

If you are struggling to get your garage door open, it’s most likely that one of the sensors is stuck. This can be frustrating when trying to leave for work and going up against a broken garage door.

This article will cover the most common ways you can fix or bypass your garage door sensors by using methods like disconnecting them and opening them manually.

Can You Bypass Garage Door Sensors?

Yes, you can bypass the sensors by setting the garage door to manual mode. If your garage door sensors are not working, it is best to call a repair company. However, if you are comfortable with DIY repairs and want to try to bypass the sensor, there are ways to do so. You can disconnect the garage door opener from the garage door or disable the sensor completely.

One of the most well-known methods is to step over the infrared light that is used as the sensor. If your steps avoid the light, the garage door will continue to close. Another way to bypass sensors is by disconnecting the garage door opener from the garage door. This can be done by either removing or disabling the power connection between the two devices.

Are there any other risks associated with bypassing garage door sensors?

Bypassing garage door sensors can have some negative consequences, including the risk of theft, damage to your home or car, and false alarms. Bypassing these sensors can also make it difficult to open your garage on time if there is an emergency.

If you’re unsure whether you should bypass a sensor, always consult a professional before doing so.

Basic Tools For Bypassing Garage Door Sensor

If your garage door sensor is not working and the door is stuck open, you may be able to bypass it using some basic tools. You will need a microfiber cloth to clean the sensor lense, a screwdriver, measuring tape, a hammer, and two pieces of 2×4 timber that are the same height as the position of your door above the ground.

How To Bypass Garage Door Sensors [Step-by-Step]

Step 1: Clean the lenses of your door sensors

Clean the lenses of your door sensors to ensure they are receiving a clear view of the surrounding area. This will help your sensors to detect obstacles and open the door accordingly.

Step 2: Check if the sensors are positioned properly

To bypass garage door sensors, you first need to check to see if the sensors are positioned properly. The sensors should be placed at least two feet from any obstruction, and they should be facing the opening of the garage.

If the sensors are not positioned correctly, they may not be able to detect when someone opens or closes the garage door. This can lead to accidental openings or closings, which could damage your car or cause other problems. By checking to make sure the sensors are positioned properly, you can avoid these issues.

Step 3: Check your garage door sensor wiring for Loose or damaged wiring

Check for any loose or damaged wires coming from the sensors. Second, turn off power to the garage door by flipping the breaker switch to avoid any potential injuries. Finally, contact a qualified electrician to fix any wiring issues.

Step 4: Try to get the door closed

Try to get the door closed and disengage the sensors. Disengaging the sensors is one way- this means that the door will stay closed even if something or someone hits it. However, sometimes the sensors stop working even when the garage door is closed, so it’s important to check regularly to make sure everything is still in order.

Step 5: If you can’t close the garage door, try to prop it open

If your garage door is stuck open, you can try to prop it open using a piece of wood. If you don’t have any 2×4 timber handy, any strong piece of wood will do the trick. It’s also a good idea to disengage the sensors when your garage door is closed.

Step 6: Put the door into manual mode

Try and release it manually by pulling the emergency release cord, which is attached to the trolley in the center of the door. If that doesn’t work, make sure you’re at home with your car out of danger before pulling the release rope. If all else fails, contact a repair service.

Step 7: Open the door manually

If you can’t open the door with your remote, there’s a good chance that the garage door sensor is malfunctioning and needs to be replaced.

There are two ways to open the door manually – by pulling down on the red cord or by having someone else pull down on the cord in the direction of the motor.

Step 8: Replace your garage door sensors

Replacing your garage door sensors is a fairly simple process that only requires a few tools and some basic electrical knowledge. You’ll need a wire cutter and a white and black cord.

Strip the ends of the white and black cord so that you can expose the metal wiring inside the casting. Cut the white and black cord about one inch long so that it will disconnect your safety sensors from the garage door.

Reattach new sensors to your garage door using metal wiring exposed by stripping its ends.

Replace your garage door sensors to bypass the sensor signal and open your garage door remotely. This can be done by replacing the old sensors with new ones.

How to Bypass Your Garage Door Openers/Sensors Permanently [Step-by-Step]

1. Cutting Garage Door Sensor Wires

Disconnect the power supply to the automatic door opener by cutting the wires with wire cutters. Tape up the ends of the wires with electrical tape to prevent them from touching each other and causing a short circuit.

2. Taping the Sensors Together

By taping the sensors together, you are preventing the garage door opener from working. This can be done temporarily until the sensors need to be replaced. When the time comes, you will need to replace the sensors and re-tape them in place.

3. Rewiring the Door Sensors

When rewiring your garage door opener, you will first want to identify the four separate holes that will allow for wire connections.

The two farthest left blocks- the red and first white- should be ignored. Instead, look at the second white block and the black or gray block. These two blocks will be where you will attach the wires of your sensors.

Now look at your sensors:

They should each have two wires, one white and one black. Wire the two white ones together and connect them to the white block on your garage door opener. Do the same with the black wires.

4. Storing the Sensors

To store the sensors, you will need to stack them on top of the door opener. The five inches of wire will give you enough room to lay the sensors safely without any danger of them disconnecting randomly. Now, you will have a permanent bypass for your garage door sensors.

Storing the sensors can help to prevent your garage door from being opened by accident. This is especially useful if you live in a complex or high-rise building where there are multiple garages.

Troubleshooting Your Garage Door Sensors

Check for Blocked Sensor Path

A blocked sensor path is a problem with one or more of the sensors in your garage door system. It can cause the door to not open or close properly, and may also result in false alarms.

If one or more of your garage door sensors is malfunctioning, it can cause problems with your system as a whole. In some cases, this may cause the door to not open or close properly, or may even trigger false alarms.

To check for and fix any blocked sensor paths in your system, start by checking each sensor individually. If one of them is causing the problem, you’ll need to replace that sensor.

Check for Loose Wires

One way to check for loose wires is to try reconnecting the sensor’s power cord. If the sensor still doesn’t work, it may be due to a loose wire. You can also try tightening any screws that hold the sensor in place.

Finally, you can test the sensor by closing and opening the garage door several times. If it doesn’t work after those three steps, it may be due to a loose wire.

Check Dirty Sensor Lenses

A dirty sensor lens is a component of your garage door that helps to send the correct signals to your opener. If this component is not working properly, it can cause your garage door to malfunction.

Garage doors use sensors to open and close automatically based on the amount of light reaching them. If one of these sensors is not working correctly, the door may still try to open or close even when it’s not supposed to. This can cause serious damage to your door and potentially lead to theft or vandalism.

To keep your garage door in good condition, check for dirty sensor lenses every month and replace them if necessary. This will ensure that your system is sending accurate signals and preventing unnecessary repairs from happening.

Check if the door Sensors are Not Aligned

A sensor is a device that detects movement or changes in the environment and sends a signal to the garage door opener. When your sensors are not aligned, this can cause your garage door to not open or close properly.

If one of your garage door sensors isn’t aligned, it could be causing problems with the door opening and closing.

Check for any debris or damage around the sensor area. Remove any obstructions from between the sensor and the wall or ceiling where it’s installed.


The conclusion of this article is that you can bypass garage door sensors in a variety of ways and that there are various ways to disable or fix them if they do not work properly. If your garage door sensors are not working properly, you can try a few different methods to fix the problem.

You can disconnect the sensors, open the door manually, or by using a chamberlain opener. If you have any other questions or tips, please subscribe to our mailing list for more Smart Home tips.
