GARAGE DOOR OPENER PROGRAMMING - UNIVERSAL 

Garage Door Opener Programming 

The GDO is programmed by using the customer's hand-held transmitter(s).

IMPORTANT: Do not use the garage door opener (GDO) with any garage door opener that 

does not have the stop and reverse safety feature. This includes any garage 
door opener model manufactured before April 1, 1982. 
Be sure that people and objects are clear of the garage door you are 
programming.

Turn the ignition OFF while programming the GDO transmitter. Follow these steps to program up to 3 
channels: 

1. If you have previously programmed a transmitter, proceed to Step 2. Otherwise, hold down the 2 outside 

buttons on the GDO transmitter for approximately 20 seconds, until the light on the GDO transmitter 
begins to flash rapidly. Then release the buttons. This procedure erases any previous settings and 
initializes the memory for all 3 channels.  

2. Decide which of the 3 channels you want to program to the transmitter you have.  

3. Hold the end of the hand-held transmitter against the front surface of the GDO (less than 1 inch) so you 

can still see the light.  

4. Using both hands, press the hand-held transmitter button and the desired button on the GDO transmitter. 

Continue to hold both buttons through Step 5. 

5. Hold down the buttons on both transmitters until you see the light on the GDO transmitter flash slowly 

and then rapidly. The rapid flashing, which could take up to 90 seconds, indicates that the GDO 
transmitter has been programmed. Release the buttons on both transmitters when the light starts to flash 
rapidly.  

Training the GDO for Rolling Code Receivers 

This procedure is for training the customer's rolling code garage door openers to their GDO transmitter. The 
GDO must already be programmed to its hand-held transmitter. The training process below must be completed 
within 30 seconds or it must be repeated. 

1. Locate the train button on the garage door opener receiver. Refer to the operator's manual for the garage 

door opener (or call HomeLink(tm) at 1-800-355-3515 for assistance). Follow instructions for the garage 
door opener in order to determine when the unit is in train mode.  

2. Return to the GDO transmitter in the vehicle, and press the button that you want trained for rolling codes 

3 times, for 1 second each time. If not successfully programmed, try 2-5 seconds each time.  

3. Press the button used again in order to verify that the GDO transmitter has been programmed.  

You may use either the hand-held transmitter or the GDO to open the garage door. 

The GDO is compatible with most, but not all, types and brands of transmitters. If the GDO light does not flash 
rapidly after 90 seconds, there may be a compatibility conflict with the transmitter used to program the GDO. 
Call HomeLink(tm) at 1-800-355-3515 in order to address compatibility concerns. 

Erasing Channels 

IMPORTANT: The GDO is compatible with most, but not all, types and brands of 

transmitters. If the GDO light does not flash rapidly after 90 seconds, 
there may be a compatibility conflict with the transmitter used to program 
the GDO. Call HomeLink(tm) at 1-800-355-3515 in order to address this 
problem.
