Does physically using the key in door arm/disarm alarm?

[kdub]

If I opt not to use my remote to lock and unlock my door, and physically stick the key in the door to lock/unlock, does my factory alarm still arm/disarm?

Also, the transponder in the key has nothing to do with the alarm right? and only for the ignition immobilizer?

Third question that's kinda related to the second one. If I buy a new key, does it need to be programmed to work with the alarm? or the programming needed is strictly for the ignition immobilizer so I can start the car?

I guess to sum up what I want to ask is, is the ignition immobilizer independant from the alarm system?


I've been reading threads after threads of cases (both here and renntech) where people are locked out of their cars when the battery dies. This is so scary and I am afraid it will one day happen to me. Why did Porsche design the door and trunk locks by electrical only??! That is so stupid. They totally haven't given the owner a way to get into the car if and when the battery dies. Unbelievable
