SmartKey with KEYLESS-GO*
Vehicles equipped with KEYLESS-GO come
with two SmartKeys with KEYLESS-GO,
each with remote control and a removable
mechanical key.
The locking tabs for the mechanical key
portion of the two SmartKeys with
KEYLESS-GO are a different color to help
distinguish each SmartKey with
KEYLESS-GO unit.
The function of the SmartKey overrules the
KEYLESS-GO function.
The KEYLESS-GO function is integrated
into the SmartKey. On these vehicles, the
validity of the SmartKey with KEYLESS-GO
is checked every time you pull an outside
door handle.
