My friend just got a 2002 Audi A4 and he has a cool keyless entry receiver, it's got his key folded in it, and he presses a button and the key pops up, just like a switch blade knife. Can we do that something like that with ours?

 

if you want to make the housing for it , you can do anything......

 

If you want a fancy key fob you'll probably be better off buying an aftermarket alarm.
