How to Reprogram a Craftsman 3/4 Garage Door Opener

Reprogramming a Craftsman garage door opener is a simple and step by step process that will only require a few minutes to complete. Technology, including the ability to encrypt transmission codes, allows homeowners to replace worn-out remotes while still using the original opener.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Ladder
• Garage door remote
• Garage door motor

1. Locate the Learn or Smart button. All motors produced in the past several years have a Smart button on the motor. This can be located next to the adjustment screws on the back or side of the motor. Note that a plastic panel may have to be moved to see the button. Depending on the model of the motor, some buttons are purple and others may be red.

2. Push the Smart button until it displays a solid light. Most of the light-emitting diode (LED) lights beside the button are green but colors may vary. You must complete step 3, below, within 30 seconds of finishing step 2.

3. Push the button on your remote that you want to correspond with the motor that is being programmed. Once the button has been pushed, the LED will flash; the remote has been programmed.

4. Repeat steps 2 and 3 if there are additional buttons to program. The process also may be repeated to accommodate additional remotes.

Tips & Warnings

• Locate the Smart button before trying to program at all. It will make the process go smoother.
