Hello My Name Is Angel I have a 2000 Lexus GS 300, Yesterday I used an un program key to start my vehicle, so I got the correct key that Ive been using all along and ever since that my car does not start at all it does is crank and crank like if I was to have the key In the ignition without a chip in it, all electrical components work fine . Do I need to have the Ecu reflashed? Or should I just tow it to the dealer. Please Help...
