KEYLESS IGNITION OPERATION:
The 2013 Lexus GS series vehicles do not require the operator to insert a key into a key
cylinder to unlock a door or start the vehicle. These vehicles “sense” the proximity of the
key and will unlock the door(s) with the key close to the vehicle and when contact is
made with the outside door release handle. Once the keys are inside the vehicle the
operator can now use the push button start/stop feature of this vehicle. When the on-
board computer senses that proper key is in the vehicle, the green LED in the “ENGINE
START STOP” button will illuminate. To turn the ignition to the accessory position,
depress the button once and items like the radio or on-board navigation system will
become active. A second press of the button will turn the vehicle to the “ON” position
where items like the instrument gauges will operate. To start the vehicle, the operator
needs to depress the brake pedal then press “ENGINE START STOP” button until the
engine starts. To shut the engine off, depress the “ENGINE START STOP” button
again.
If there is a problem with the transponder or the battery in the key fob, a display should
appear in the middle of the instrument panel like the one shown below.
