HELP - replaced key she'll on my 2006 Audi A4 and car went to safe mofe
 

Hey guys!! Pls help
So that's what happened is that my original flip key broke a bit and I though ow.. I'll buy one (eBay) and replace it.. It's just a plastic cover.
SO.. I did and when I went to try it on my car.. The remote didn't work, I've opened the door with the key and started the engain and it shot down after 2 sec and went into SAFE mode.

So I searched the web and found the way with shorting the battery and reprogramming the new key.. But didn't work..
Thoughts anyone?

Thank you so much! Don't want to tow it to the dealership.. It might go up to 600$ /:
