Examine the garage-door control panel to locate the series of switches used to set the door codes; the switches are labeled "S1," "S2," "S3" and "S4."
Flip "S1" into the "On" position to set the first user code.
Use the numeric keys on the electronic keypad to enter your desired user code. Select a user code that is between two and five digits; make the code easy to remember, but too difficult for others to guess.
Flip the "S1" switch back to the "Off" position. A tone will sound to indicate that the code was successfully programmed into memory.
Use the same process to set user codes for switches "S2," "S3" and "S4."
