Some time ago I installed an AutoMate keyless entry in my 94 S4. It was pretty easy and it automatically enables/disables the stock alarm when it locks/unlocks. Well, the remote for it is pretty hideous and I wanted to make an all in one key. I first tried to make one with the remote in the key but it wouldn't hold up to the twist pressure. So I then ordered a flip keyfob and tried transplanting the electrics into it but it didn't work as the buttons wouldn't quite line up.
So, I just ordered an alarm system with flip key remotes included. I am not using the alarm function so I don't have a door switch, motion detector or siren connected. It was a cheap system and I was able to cut down a spare key to fit into the flip part. It is SO much better than having a key and separate remote. Now it is like any modern one.
Here is the system I ordered;

and here is how it turned out
If anyone is interested I can provide you with what wires to connect to on the stock alarm box.
