Additional Sub-Key Registration

WARNING: This page is about a different car, the 2003 Lexus IS 300 and 2002 Lexus IS 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 performed while the timer is working, the timer completes counting time, then next timer starts.

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