I have a 2004 996 and when I unlock the doors using the key in the lock, the alarm goes on after 10s unless I put the key in the ignition and turn it to accessory. When I use my remote to Unlock, I have no issue (the alarm system get deactivated at the same time as the door get unlock)

Any idea what is goign one?

I know the manual mention that this "might" happen, but they do not say why or how to prevent it?

My understanding is that is the way it is supposed to work. Same thing happens on my Cayenne too. I imagine it is a security feature, so if someone gets the door unlocked somehow and has no key the alarm starts sounding to prevent theft.

That is weird!

I usually do not carry the "big key" with the remote (too big) so I usually use the "spare key" that has no remote. I also have a 2000 Boxster and I do the same with it (use the sapre key) but I never notice that behavior on it!?...

The manual talks about about an "Emergency operation"

"Unlock the driver's door with the key at the door lock. Open the door and switch the ignition within 10 seconds in order to prevent the alarm system from being trigger". So I assume what they call "emergency operation" is to use the key instead of the remote to unlock the car. I was thinking that I had "enabled" the "emergency operation mode" by doing some cryptic key lock/unlock sequence!
