Things You'll Need
Small screwdriver (optional)
A remote-controlled garage door opener is a convenience that has become a typical feature in most homes with an enclosed garage. The hand-held remote unit is a simple transmitter that activates the door opener's motor to raise or lower the garage door. Whether you are adding an additional remote control or replacing a lost or damaged remote, you only need to program the new remote to match garage door opener's radio frequency.
Video of the Day
Access the garage door opener motor housing. Remove the plastic light lens cover, if applicable. The short remote control wire antenna and the "Learn" or "Set" button are typically under this cover. For units with no removable light cover, the button will be on the same side as the wire antenna.
Depress and hold the "Learn" or "Set" button located near the short wire antenna until the activator light turns on. The illuminated activator light denotes that the opener's remote frequency is broadcasting a continuous signal, typically for 30- to 60-seconds.
Depress and hold the button labelled "L", "Learn" or "Set" on the new remote control unit. Hold the button down until the activator light on the garage door opener starts flashing, then release the button.
Replace the opener's plastic light cover, if applicable, and test the remote control for proper activation of the garage door opener.
Dip Switch Remotes
Access the garage door opener motor housing. Remove the plastic light lens cover, if applicable. The short wire remote control antenna and dip switch console are typically under this cover. For units with no removable light cover, the dip switch console will be on the same side as the wire antenna and may be exposed or have a small plastic cover that you need to be remove with a small screwdriver.
Note the dip switch setting. Each of the 3, 4 or 5 dip switches will be numbered and this sequence of numbers is the opener's frequency setting.
Turn the new remote control unit over and remove the battery cover. This cover usually snaps into place and is removed by sliding the cover off the remote using your thumb or a small screwdriver. The dip switches for the remote will be under this cover. You may need to remove the battery to expose the dip switches.
Set the dip switches to the setting recorded from the garage door opener in Step 2.
Reinsert the remote control's battery, if applicable, and replace the battery cover.
Replace the garage door opener's plastic light cover, if applicable, and test the remote control for proper activation of the garage door opener.
