The RX330 comes with 2 keys. one remote with buttons and one valet key with no buttons and no remote controls.

The one with buttons have 2 forms of programming required. First, for the remote function to control the doors and/or windows, the second to start the car itself with the key in the ignition.

You can program the remote function yourself with a door procedure, however ,the key itself can only be programmed by the dealer for the car to start. The same programming applies to the valet key.

Unfortunately unless you have the other key, you will need to contact a Lexus dealer.

Only your dealer would have the specialist equipment to check the transponder in your key and the immobiliser system in the car. Fixing either is relatively simple: replace the key or just the transponder, or the ECU, for that is where the immobilser system "lives".
