So way back when I bought my car it didn't come with the switch blade alarm module thingy. I guess the previous owner lost it or whatever. It only came with the key from it. So I remembered I still had my old Audi key from my A4 B5. So I just opened it up and swapped the keys. The actual button for the key to flip out didnt fit. But I just manually pull it out. And obviously the alarm and stuff doesn't work but Definately better than holding a little key and rish the chance of loosing it. I did this the second day I got the car. I just forgot to show it off til today
