WARNING: This page is about a different car, the 2003 Lexus RX 300 and 2002 Lexus RX 300. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

It is possible to register up to 3 sub-key codes including the already registered key code.
When any operation time described below is over, registration mode completes.
When the next procedure is started while the timer is working, the timer completes counting time, then the next timer starts.

There are 2 ways for registration of an additional sub-key:

Depressing Brake Pedal And Acceleration Pedal - Refer to flowchart, see Fig 1.
Using Hand-Held Tester - Refer to flowchart, see Fig 2.
