I have the same car.
So it looks like (according to you) that the alarm is working... just no sound.
The alarm is seen by removing the front floor mat... BOTH LAYERS. Then unscrew the 1 screw holding the black metal cover. Remove that. The alarm is the black box to the left with 2 plugs on it. Make sure both are in tight and that they have not been cut into.
If everything looks ok, check the wiring harness' from the alarm down through the black cover on the right of the floor. See if anything has been cut.
