There should be a program button on your garage door motor.
heres the instructions from the KK manual
Programming HomeLinkBefore You BeginIf you have not trained any of the HomeLink buttons,
erase all channels before you begin training.
To do this, press and hold the two outside buttons for
20 seconds until the red indicator flashes.
It is recommended that a new battery be placed in the
hand-held transmitter of the device being programmed
to HomeLink for more efficient training and accurate
transmission of the radio-frequency signal.
Your vehicle should be parked outside of the garage
when programming.
1. Turn the ignition switch to the ON/RUN position.
2. Hold the battery side of the hand-held transmitter
away from the HomeLink button you wish to program.
Place the hand-held transmitter 1–3 in (3-8 cm) away
from the HomeLink button you wish to program while
keeping the indicator light in view.
3. Simultaneously press and hold both the chosen
HomeLink button and the hand-held transmitter button
until the HomeLink indicator changes from a slow to a
rapidly blinking light, then release both the HomeLink
and hand-held transmitter buttons.
Watch for the HomeLink indicator to change flash rates.
When it changes, it is programmed. It may take up to
30 seconds, or longer in rare cases. The garage door may
open and close while you train.
NOTE:
• Some gate operators and garage door openers may
require you to replace Step 3 with procedures noted in
the “Gate Operator/Canadian Programming” section.
• After training a HomeLink channel, if the garage
door does not operate with HomeLink and the garage
door opener was manufactured after 1995, the
garage door opener may have a rolling code. If so,
proceed to the heading “Programming A Rolling Code
System.”
4. Press and hold the just-trained HomeLink button
and observe the indicator light.
If the indicator light stays on constantly, programming is
complete and the garage door (or device) should activate
when the HomeLink button is pressed.
If the indicator light blinks rapidly for two seconds, and
then turns to a constant light, continue with programming
for a Rolling Code.
5. PROGRAMMING A ROLLING CODE SYSTEMAt the garage door opener motor (in the garage), locate
the “Learn” or “Training” button.
This can usually be found where the hanging antenna
wire is attached to the garage door opener motor (it is
NOT the button normally used to open and close the
door).
6. Firmly press and release the “Learn” or “Training”
button. The name and color of the button may vary by
manufacturer.
NOTE: There are 30 seconds in which to initiate the next
step after the “Learn” button has been pressed.
7. Return to the vehicle and press the programmed
HomeLink button twice (holding the button for two
seconds each time). If the device is plugged in and
activates, programming is complete.
If the device does not activate, press the button a third
time (for two seconds) to complete the training.
If you have any problems, or require assistance, please
call toll-free 1–800–355–3515 or, on the Internet at
http://www.HomeLink.com for information or assistance.
To program the remaining two HomeLink buttons,
repeat each step for each remaining button. DO NOT
erase the channels.
It took me a couple tries to get i right, but its works great now!
