Hello everyone,

So've I've been having the notorious flashing key light for some time now. None of my remotes work (replaced the batteries) and eventually the car wouldn't start. With the advice of some members on here, I was able to re-register the key and it would start. The thing is, if I leave the car over night and try to start it the next morning it won't start again. I have to re-register the key in order to get it started. Funny thing is that the key works fine all throughout the day but somehow "resets" when I leave the car overnight. I removed the rear bumper to try and clean the rear antenna like many people have done but when I removed it, there was no antenna?!? The only cable there was the one that connected to the license plate light. Is this also used as the rear antenna?? I have a '04 6-speed. Thank you in advance for any help.
