Using these garage door openers can
increase the risk of serious injury or death.
For further information, contact HomeLink
at 1-800-355-3515 or www.homelink.com
or an Authorized Mazda Dealer.
Always check the areas surrounding
garage doors and gates for people or
obstructions before programming or
during operation of the HomeLink system:
Programming or operating the HomeLink
system without verifying the safety of areas
surrounding garage doors and gates is
dangerous and could result in an
unexpected accident and serious injury if
someone were to be hit.
NOTE
The programming will not be erased even
if the battery is disconnected.
▼Pre-programming the HomeLink
System
NOTE
It is recommended that a new battery be
placed in the hand-held transmitter of the
device being programmed to HomeLink
for quicker training and accurate
transmission of the radio-frequency signal.
Verify that there is a remote control
transmitter available for the device you
would like to program.
Disconnect the power to the device.
▼Programming the HomeLink
System
CAUTION
When programming a garage door opener
or a gate, disconnect the power to these
devices before performing programming.
Continuous operation of the devices could
damage the motor.
The HomeLink system provides 3 buttons
which can be individually selected and
programmed using the transmitters for
current, on-market devices as follows:
1. Disconnect the power to the garage
door opener or gate programmed to the
hand-held transmitter.
2. Position the end of your hand-held transmitter 2.5 ―7.5 cm (1―3 inches)
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 and hand-held
transmitter buttons. Do not release the
buttons until step 3 has been
completed.
NOTE
Some gate operators and garage door
openers may require you to replace
this Programming Step 2 with
procedures noted in the “Gate
Operator/Canadian Programming”
section.
4. After the HomeLink indicator light changes from a slow to a rapidly
blinking light, release both the
HomeLink and hand-held transmitter
buttons.

5. Connect the power to the garage door
opener or gate programmed to the
hand-held transmitter.
6. Firmly press and hold the programmed
HomeLink button for five seconds, and
then release it. Perform this operation
two times to activate the door or gate.
If the door or gate does not activate,
press and hold the just-trained
HomeLink button and observe the
indicator light.
If the indicator light stays on
constantly, programming is complete
and your device should activate when
the HomeLink button is pressed and
released.
NOTE
To program the remaining two
HomeLink buttons, begin with
“Programming” ― step 1
If the indicator light blinks rapidly for
two seconds and then turns to a
constant light, continue with
“Programming” steps 7 ―9 to
complete the programming of a rolling
code equipped device (most commonly
a garage door opener).
7. At the garage door opener receiver (motor-head unit) in the garage, locate
the “learn” or “smart” button. This can
usually be found where the hanging
antenna wire is attached to the
motor-head unit.
8. Firmly press and release the “learn” or
“smart” button. (The name and color
of the button may vary by
manufacturer.)
NOTE
Complete the programming within 30
seconds.
9. Return to the vehicle and firmly press,
hold for two seconds and release the
programmed HomeLink button. Repeat
the “ press/hold/release ” sequence a
second time, and, depending on the
brand of the garage door opener (or
other rolling code equipped device),
repeat this sequence a third time to
complete the programming process.
HomeLink should now activate your
rolling code equipped device.
NOTE
To program the remaining two HomeLink
buttons, begin with “Programming” ―
step 1

▼Gate operator/Canadian
Programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
―
which may not be long enough for
HomeLink to pick up the signal during
programming. Similar to this Canadian
law, some U.S. gate operators are designed
to “time-out” in the same manner.

If you live in Canada or you are having
difficulties program ming a gate operator
by using the “Progr amming” procedures
(regardless of where you live), replace
