I recently changed the battery of the remote key and off coarse I had to take it apart :-), so I took some pictures of it. (Naturally)

BTW:

1) The key itself is a separate part, all steel, no electronics.

2) The black plastic housing contains the "starting code"; a 4x10 mm magnet-like thingy clipped in one half of the housing.

3) The remote part has got nothing to do with the rest at all, the only function is to send a signal to open the car (Mux; for 30 seconds).

This all means; opening the car with the right code does *not* mean you disarm an eventual original alarm, and one can start the car with a screwdriver and a hammer. It still fails the transponder-code imbedded in the housing.

Oh, and the radio code sits in the ECU, so even if it gets stole it will *never ever* play without the car's computer. You'll need the dealer's maintenance-station for that.

So, you all know.
