How to change code on garage door opener?


Changing the code on a garage door opener is an essential task for maintaining security and ensuring that only authorized individuals can access your garage. Whether you need to update the code due to security concerns or simply want to reset it, this article will guide you through the process of changing the code on a garage door opener.

Step 1: Identify the Garage Door Opener Type

Before you can change the code on your garage door opener, it’s important to determine the type of opener you have. There are three common types:

1. Dip Switch: This type of opener uses a series of small switches (dip switches) to set the code. These switches are usually located on the motor unit or the remote control itself.

2. Rolling Code: Most modern garage door openers utilize rolling code technology. This means that the code changes every time the remote control is used, making it more secure. To change the code on a rolling code opener, you’ll need to follow specific instructions provided by the manufacturer.

3. Keypad Entry: Some garage door openers have a keypad entry system that allows you to enter a code directly on the keypad to open the door. Changing the code on this type of opener usually involves accessing the programming menu on the keypad.

Step 2: Gather the Necessary Materials

The materials you’ll need to change the code on your garage door opener will depend on the type of opener you have. However, here are some common materials that may be required:

– Screwdriver
– Ladder (if necessary to access the motor unit)
– New remote control (if changing the code on a remote control)
– Owner’s manual or programming instructions provided by the manufacturer

Step 3: Follow the Manufacturer’s Instructions

To ensure that you change the code correctly and avoid any potential issues, it’s crucial to follow the manufacturer’s instructions. These instructions can usually be found in the owner’s manual or on the manufacturer’s website.

If you have a dip switch opener, you’ll need to open the remote control and set the switches to the desired code. Make sure to match the switches on the motor unit with the ones on the remote control.

For rolling code openers, the process typically involves pressing a specific combination of buttons on the remote control and then entering the new code. Again, refer to the manufacturer’s instructions for the exact steps.

If you have a keypad entry system, you’ll need to access the programming menu on the keypad and follow the instructions to change the code. This may involve entering a master code or using a specific sequence of buttons.

Step 4: Test the New Code

Once you’ve changed the code on your garage door opener, it’s essential to test it to ensure that it’s working correctly. Stand within range of the opener and use the new code or remote control to open and close the garage door. If everything is functioning as expected, you’ve successfully changed the code.


Changing the code on a garage door opener is a relatively straightforward process, but it’s important to follow the manufacturer’s instructions to ensure proper execution. By identifying the type of opener, gathering the necessary materials, and carefully following the provided instructions, you can maintain the security of your garage and control access to it.
