SMART ENTRY SYSTEM AND
PUSH-BUTTON START
The GS450h smart entry system consists of a smart
key transceiver that communicates bi-directionally
enabling the vehicle to recognise the smart key in
close proximity to the vehicle. Once recognised,
the smart key will allow the user to lock and unlock
the doors without pushing smart key buttons, and
start the vehicle without inserting it into an
ignition switch.
Smart key features:
•
Passive (remote) function to lock/unlock the
doors and start the vehicle.
•
Wireless transmitter to lock/unlock the doors.
•
Hidden metal cut key to lock/unlock the doors
from the exterior door lock.
Door (Lock/Unlock)
Three methods are available to lock/unlock
the doors.
1. Pushing wireless smart key lock/unlock buttons.
2. Touching the sensor on the backside of any
exterior door handle, with the smart key in close
proximity to the vehicle, unlock the doors.
Pushing the lock button on any exterior door
handle locks the doors.
3. Inserting the hidden metal cut key in the drivers
door lock and turning clockwise once unlocks
the driver door, twice unlocks all doors. To lock
all doors turn the key counter-clockwise once.
