I dont know about 2002 saloon, but my car has those web design rims with a key fob. the key fob in this video is not original, the owner has changed from the original fob to this new model fob. I have these two fobs for keyless entry and a simple key
This is the original fob. no aftermarket. the best thing i like about this is that if any door is not close completely, you wont be able to lock the car, which indicates that any door is not closed completely or still open. Also if you unlock the doors and non of the door get opened in the next 10 seconds approx, not sure, the car's door is locked automatically. It does not have the feature of locking the doors when applying brakes or at speed, doors get lock like an after-market keyless entry.
