Chasing down an intermittent problem is always tough but I can tell you how to disable it.

Remove the lower dash panel on the drivers side of the car (3 T-25 Torx)and look to the left of the steering column, high on the firewall, for the lower central electrical unit. It is just below your fuse box on the inside of the car and it is a bunch of relays.

Once you locate it find relay 210/211 and remove it. This disables the alarm but it also enables the immobilizer and the car will not start. Look on the base of the 210 side of the relay and molded into the plastic you will find pin numbers. Locate pins 50e and 50f. You will need to make a jumper wire to fit the socket positions associated with those 2 pins to get the car to start again.

The dealer can get you a replacement dummy relay number 210 that has the jumper wire built in. It is part number 3545333 but I have no idea what they charge for it.
