-   same problem here. on bimmerfest.com there are lots of other people who are having the same problem too.
suggestions as to cause so far:
1) hood (bonnet) sensor malfunction: unplug this to see if problem is remedied
2) apparently the factory fit siren has a back-up battery. if this runs low, people say it coulld cause the alarm to go off ?!-   Guest

My 2004 Pacifica is in immobilizer mode. I have only ONE key, properly programmed, of course, but I'd lost it, and in an attempt to see if I'd left it inside the car, well, I basically opened the car door through the ajar window......DUMB, DUMB, DUMB. Had I known this would've been the outcome, Id have waited until I found the key. (Which, by the way, I found 14 hours later, after having gone through my house like a mad woman.............was under the REFRIGERATOR!). So, like a MORON, I opened the door, thus, enabling the alram. In a panic I pulled the positive terminal to the battery...........and.........well, here I am. After having assumed (once I found the key, that is) it was the battery, I jumped it, then discovered the "service immobilizer" light on the dash-flashing, ever so mockingly at me, as if were saying "kiss my A**, moron, I aint doin' nothing').
I am literally stuck here, at home-39 miles from closest dealer. Plus, my one and ONLY experience with that particular dealer was less than admirable (on their part), and I had to obtain legal representation; I took it there for brake pads, left with a $4300 bill for alternator replacement, exhaust replacement, rotors, a/c control module replacement-of which NONE were never even discussed, let alone failing or "bad" too begin with. So, that is the last place I need to go right now.
ANYWAY.........
If you can definitely help me disable it, please respond! Although, please know, that I have only one key; it is my understanding that I need 2? Help! I'm desperate!
