I have somehow scrambled my keyless entry garage entry code. How do I reset it?

Locate the learn button on the unit. It is orange or red probably under the light panel. Press and release the learn button. This button turns the receiver on for 30 seconds. Within this 30 sec. you must enter your new 4 digit PIN into the keypad and hold enter button for 5 seconds. When the light on the keypad stops flashing, test your new code by entering the 4 digit PIN and ENTER.
