2001 RX300

The following works on the newer Lexus products. Not sure if it will work on a 2001 but it is easy to try: ==========================================================================Setting the door lock function Got this from the dealer the other day. You can set the following auto door locking and unlocking functions. All times must be EXACT or it will not work.

(a) Locking linked with the shift position

All the door 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.

Setting the functions

1. Close all the doors.
2. Turn the ignition switch to the "ON" position.
3. Within 10 seconds after the ignition switch is turned to the "ON" position;

+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.

If you want to cancel a function, repeat the procedure. Each time you perform the procedure, the function is set or cancelled.

It is unfortunate that the programming instructions are so easy. I would have liked to see something like:

1. Press and hold the brake pedal down.
2. While the brake pedal is held down, wind up and down the rear right passenger window at 15 second intervals while holding down the front passenger door lock for 2 minutes.

If I am going to pay a Dealer to do it, I want to get my money's worth :)
