156 Sportwagon Alarm Remote Key broken

Thought I would post this for anyone else that may have this problem... My remote alarm / locking keys both stopped working. I could open the car with the key but the alarm would go off even if the car was started.
I solved the problem of the constant alarm by unplugging the alarm:

1. The siren and control box is in the near side front wing. Jack the car up, remove the wheel and remove the wheel arch liner.
2. Unplug both plugs going onto the siren
3. The siren will continue going off for 15 minutes until its internal battery dies!

The car will then be useable until you can get an alfa dealer to sort a new remote (at a cost of £140).

2002 2.4JTD Sportwagon by the way!

Thread resurrection people.....

I have just fixed my 2003 156SW key by soldering the microswitch back on.

In preparation for when it next fails and the car is locked with the alarm ON.....how do you disable the alarm once you open the door manually with the key blade?

Is there an easier way than the OPs method?
