First if all, I am a rookie so take it easy on me, but hello to all. I have a 99 GS300.

I did the programming for a master key and when I go to start the car it will not turn over. I can unlock the doors, pop the trunk and everything else, but it will not let me start the car. My first master key works, but this second one is giving me problems.
(Also, after the car accepts the key it still locks twice, saying its rejecting even the I can open doors and trunk. And when I put the key in the ignition, the security light still blinks).

I also tried the brake/accelerator programming to try to start the car up with the key and it still does not work.

Does anybody have any suggestions to help me??? Do I have to go to the dealer for this matter??

Thanks
