Can I just disable my factory car alarm?

Recently my battery died and I can not disable the alarm because my key fob is not working nor does the driver side door lock

I just want the alarm system gone so I can start the car.

If I'm correct you can just take the panel under the passengers side off, and pull the wiring harness off the alarm, which should be sitting on top of the panel.

Does anyone really think that by - passing the alarm should be this easy?

there's what your factory alarm should look like.. I would try that solution - I may be wrong though, I've only dealt with aftermarket alarms.

From past experience.. with *cough* fords... You have to train the system to recognise the key again before it will play nice.

In the case of fords, it required the key being inserted, turned to position II while pressing something. 30mins later.. yay it was happy.

I'm sure BMW would do something similar to make sure things were secure. A dealer would definitely know.
