For a mathematician, you write very well. Thank you for clarifying this matter. I have just bought a 1991 LS400. I noticed that the key and the car do not 'talk' i.e. no central locking function. Do you know the procedure to get the car and the master key talking again? I have put a new battery in the master key. Femi I also have just bought a 1994 SC400 and replaced the battery but still have had no luck in figuring out how to get it working once again. Any help would be greatly appreciated.
