Question

There is no antenna on mine just small hole , is it missing or is it inside barrel ,

Answer 1

Hi there

The antenna and immobilizer are screwed to the key cylinder. This is a ring around the cylinder with a small black box connected to it. If it is missing then someone would have had to remove it and installed a different ecm from a much oldr car. Sounds like you need to get your keys reprogrammed by the dealer.
