[s-cars] Alarm system/locking system problems

[Larry]

I thought central locking was supposed to auto lock the car if:

1) the locks were unlocked by the remote (not the key in the door lock)
 
2) neither ANY door or the trunk/hatch were physically opened within some specified period of time (never timed it, seems to be about five minutes)

This is how my 95.5 (RF remote) functions, and has since I've owned it. If you open a door/trunk or use the key in any lock, auto lock is defeated.  I've always thought this was a feature, not a warning of a potential system failure. As I recall, my Mom's 2001.5 Passat does the same thing, but this is not something I could ever ever explain to her how to check, perhaps I can have my friend check on his '02 Passat.
