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.

Unfortunatly the alarm system is an integrated system and needs to be taken to a dealer. The alarm malfunction could be caused by a number of things including the main alarm mosule, switchs or motion sensor. Good luck

Conversation Summary

The owner of a 2001 Toyota Sienna says the alarm prevents the van from starting. The electronic key makes no sound even after a battery change, no alarm switch was found under the dashboard, the relevant fuse was not identified, and locking and unlocking the driver's door with the key did not disengage the alarm. The expert says the alarm is integrated and should be diagnosed by a dealer, noting that the module, switches, or motion sensor could be at fault.
