I have tried to search for master key programming but the threads i have looked at only give instructions for programming a second master key. I recently bought an SC430. To my surprise the car was delivered with no keys so I had to go to the dealer and get a master and valet key made. I then had a locksmith reflash the ecu to accept the new keys. The instructions the locksmith gave me do not seem to work. Does anyone know the correct procedure for programming the master key and valet key? His instructions say to insert the master key in for 15 seconds remove master and insert valet key for 15 seconds without turning the key to the on position. Any help will be appreciated.

 

I am trying to upload a pdf file, let's hope it works and it can help you.

Thanks for the upload. Are these instructions for the programming of the remote part of the master key or the programming of the immobilizer part of the master key? I am looking for programming of the immobilizer part of the master key. Thanks again

 

Had some guy come and program the new master and valet keys.. Charged crazy $$$ for an hour an a half of his time but gotta pay to play i guess... Thanks for the help anyway

 

I believe I have seen one member here who has done a lot of research in that stuff, but I never paid too much attention to it.

I hope you had read all his threads before you finally decided to pay for the professional help.

 

I definately did a search. The immobilizer had to be reflashed again and the keys had to be added with a scan tool the guy brought with him...
