How to Change the Frequency on a Garage Door Opener — and When You Actually Can
Published Date: Sep 22, 2025
If your garage door remote has started acting strangely or no longer responds like it used to, frequency interference might be to blame. Maybe your neighbor’s remote is opening your garage, or you’re dealing with signal issues that weren’t there before. These situations are more common than you’d think — especially with older systems. In this guide, we’ll explain how to change the frequency on a garage door opener, when it’s possible, and what safer alternatives are available.
Can You Change the Frequency on Your Garage Door Opener?
The short answer: sometimes — but not on most modern systems. Newer openers use rolling code technology, which automatically changes the signal with each use to improve security. These systems don’t let you manually adjust the frequency.
Older models (mainly from the early ’90s or before) used fixed codes with DIP switches — small toggles inside the remote and opener. If you have this kind of setup, you can change the frequency by adjusting the switch pattern so both devices match.
How to do it: Open the remote and the opener housing. Locate the DIP switches (usually 8–12), and set the same pattern on both units. This resets the transmission code.
These older systems can still work fine, but they’re less common today and may not support newer remotes or offer the same signal protection. If you’re unsure which type you have, check the manual or ask a technician before making changes.
In most cases, especially with newer units, it’s safer and more practical to explore other solutions, which we’ll cover next.
Safe Alternatives to Frequency Changes
While direct frequency switching isn’t an option for most newer systems, there are still ways to solve signal issues without messing with the electronics.
Here are some trusted solutions:
- Reprogram your garage door remote. Often, resetting and syncing the remote solves the glitches. You can check your manual or follow our step-by-step guide on how to program a garage door remote to do it safely.
- Upgrade your opener to a dual-band or smart system. These systems automatically adjust to avoid interference from nearby devices.
- Check for local interference. Wi-Fi routers, LED lights, and other electronics can mess with your garage signal. Try moving or shielding them.
- Replace the remote. Some newer remotes work better with modern openers and may resolve the problem on their own.
These steps are safer (and usually more effective) than attempting to figure out how to change the frequency of a garage door opener yourself, especially if you’re unsure what kind of system you have.
