Disengaging my car alarm

Hi. I have a Toyota Sienna 2001 minivan and the alarm is keeping my car from starting. The electronic key does not work. I hear nothing when I press the key pad. I even changed the battery in the electronic key. I tried looking underneath the daskboard and could not find a switch for the alarm. I checked the 2 fuse boxes that I could see and did not see which fuse was for the alarm. I also locked and unlocked the driver's door with the regular key to try to disengage the allarm, but no luck.

How can I shut off or disengage the alarm?


I have already tried
Thanks.
