Owner's manual says that if car is locked with the remote, it can be
unlocked w/remote or ignition key. When opening w/key, however, the
alarm goes off. Called the local dealer and was told that the alarm
will sound for 30 seconds or so if a key is used to open the car if it
has been locked with the remote. This they said was normal. Only way
around it is to lock the car w/the key.

If this is correct, is there a way to disable the alarm?
