SmartKey
Your vehicle comes supplied with two
SmartKeys, each with remote control and
a removable mechanical key.
The locking tabs for the mechanical key
portion of the two SmartKeys are a
different color to help distinguish each
SmartKey unit.
The SmartKey provides an extended oper-
ating range. To prevent theft, however, it is
advisable to only unlock the vehicle when
you are in close proximity to it.
The SmartKey centrally locks and unlocks:

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 the
integrated signal transmitter 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 if you are having
difficulties programming a gate operator
(regardless of where you live) by using the
programming procedures, replace step 4
with the following:
Step 4:
Continue to press and hold the
integrated signal transmitter button
(2, 3 or4) while you press and
re-press (“cycle”) your hand-held
remote control transmitter6 every
two seconds until the frequency signal
has been learned. Upon successful
training, the indicator lamp1 will
flash slowly and then rapidly after
several seconds.
Proceed with programming step 5 and
step 6 to complete.
