I purchased a 2005 RX330 from a dealer in Rhode Island. The master key was lost, there was only one Master key and a spare key that can lock/unlock car manually and of course start vehicle. The Lexus dealer will NOT provide me the P/N for the remote for this car,stating than I could go then after market and attempt to get a new Master key that will operate the entire vehicle. It did not take a rocket scientist to know the dealer was right. However, I have a very limited base key only. I would appreciate any counsel how I might get a new master key made.
