TESTED ON: 2007 IS250 Sports with enhancement pack
SUCCESFUL/FAIL: FAIL
LEVEL OF DIFFICULTY: hard (assuming it's even possible!)

INTRODUCTION
In some Lexus models, it has been possible to modify the automatic lock and unlock options, linking them either to the position of the transmission or motion of the car. To date, I haven't had any luck getting this to work on either the 2007 IS250 or the 2007 RX350.

DETAIL
There are four configuration options:

A. Locking linked with the shift position
All the dooor are locked automatically when the selector lever is moved out of the "P" position with the ignition switch in the "ON" position. This is suppose to be the default setting for new vehicles.
B. Unlocking linked with the shift position
All the door are unlocked automatically when the selector lever is moved to the "P" position with the switch in the "ON" position.
C. Locking linked with the vehicle speed
All the doors are automatically locked when the vehicle speed reached 12 mph or higher. However, if any door is unlocked during driving, the auto function will not operate until the unlocked door is opened once.
D. All the doors are unlocked automatically when the driver's door is opened within 10 seconds after the ignition switch is turned from "ON" to the "ACC" or "LOCK" position.

STEPS
1. Close all the doors
2. Turn the ignition ON (press START button twice?)
3. Within 10 seconds after the ignition is turned ON:

• To set function A
  Push and hold the front of the power door lock switch for 5 seconds with the selector lever in the "P" position.
• To set function B
  Push and hold the rear of the power door lock switch for 5 seconds with the selector switch in the "P" position.
• To set function C
  Push and hold the front of the power door lock switch for 5 seconds with the selector switch in any position except "P".
• To set function D
  Push and hold the rear of the power door lock switch for 5 seconds with the selector switch in any position except "P".

All the doors are automatically locked and unlocked when you release the power door lock switch. This indicates that the functions is set. If all the doors do not lock and unlock, the time the switch was held may have been too short or too long. Perform the procedure over again starting at step 1.
