I just acquired an IS200 SE that came with only 2 master key fobs. Both start the car but the wireless entry buttons on the keys for the doors/boot don't work. The central locking cannot be activated with the key in the drivers door lock, I would have been happy to live with that. Is there any way the keys can be re-programmed. I might consider installing a car alarm with a central locking interface to enable remote locking (I bought the car cheap because of this prob).
