hi a few things > .. spray some wd40 into the ign switch itself and clean the key also with some wd40 and try it... also > www.youtube.com/watch?v=TMW7V5KhkM8..... also> Turn the ignition switch to "Off." Pull down on the top of the fuse panel lid beneath the steering column. Remove the fuse panel lid. Pull the fuse that is labeled "ECM" or "ECU." The inside of the fuse panel lid shows a chart indicating where each fuse is located. Pull the fuse straight out of the fuse panel. Turn the ignition switch to "ON" without starting the engine. Leave there for five minutes. Turn the ignition switch off. Put the fuse back into its slot in the fuse panel. See if it starts. < replace the ignition "IGN1" relay.... readhttp://repairpal.com/car-wont-start-because-of-anti- theft-system-that-uses-raised-chip-key-614.....also check for any codes
