How to Reset a Remote Control:

If you want to add another remote control for your garage door opener or need to replace a dead battery and reprogram an existing remote, chances are you'll have to reset the opener with the base unit for it to work. The process involves just a few steps and is relatively easy to do

• Replace the battery by opening the remote, taking out the old one(s) and putting in the new one(s). Make sure you buy the right battery for your remote. Match the battery type, size and voltage that came with the remote
• Use a step ladder to access the garage door motorized unit, usually equipped with a safety light. Locate the reset or "learn" button on the unit. Many times, this small button is recessed, so you might need a pen or pencil to reach it
• Push the reset or "learn" button on the opener. While the reset indicator light is blinking for about 30 seconds, point your remote at the opener, then press and hold the remote button that opens the door, and the reset light should stop blinking and glow steady to indicate the controller and opener are now synchronized. If the process doesn't work the first time, try again to make sure you pressed your button during the time when the indicator light is blinking
