Anyone the correct transponder to use? I bought a Chinese flip key that was supposed to have one in it. It didn't and when I told them they sent me one. I put it in and tried to program it but it didn't work. Took it to the dealer and they couldn't program it either. From what I can tell, it needs a id46 chip so I bought one and it doesn't work either. The numbers on both chip are, pcf7936aa. What are the chances that 2 chips are bad?
