So I purchased a 2001 IS300 (beautiful blue one) and there were two keys on the key ring. When I purchased it they had the valet key in the ignition so I didn't think to try the master key on the key ring. Come to find out the master key does not fit the car. So I have only a valet key as far as I know ( gray plastic part). The car does have a Clifford after market alarm and remote start. I am wondering if there is any way to use the module for the remote start to program a master key? I've done a lot of ready and from what I've found Lexus no longer does the key replacement program and I need to send my ECU to someone to reflash and make keys. This is where I run into my next problem. The car has an aftermarket intake and headers and as a result has a piggy back computer that screws with my O2 sensors so the dealership won't touch it with the piggy back computer. Debating if I should go back to stock intake and remove the piggy back computer then have the dealership reflash and make keys (they send the ECU to California so I would be out a car for a while) or if there is someone more local who can do it (seattle area)? is there someone who would reflash with the piggy back? Is there another way to program a master? I've had the car for a couple years now so obviously it isn't something I need done right this moment but it would be nice to have more than one key for the car. The car has over 200,000 miles so I don't really want to put a lot of money into it.
