Question about Toyota Sienna

2 Answers

Purchased used 2005 Toyota Sienna last year. It has an alarm, never had a problem with it previously. This weekend the alarm began going off for just about anything - touching the car even. It disables the car so that we are unable to start it. Only after messing with it for about 30 minutes of locking and unlocking, trying different combinations can we get the car to start. Very embarassing when this happens away from home. Is there anyway to get it back to "normal"?

It's a 2005 sienna. Do you really need a alarm? They are more trouble than they are worth. Have it removed or disabled.

you may have to disconnect the battery for a minute or so ,this will reset the alarm. check your remote it does have a battery in it. otherwise you have to look for a fuse somewhere under the dash close to the fuse box.each one is diff. depending if it original toyota or aftermarket alarm.

SOURCE: 1996 Explorer anti-theft system won't disable

Try re-setting the computer...Disconnect the negative terminal of the battery and leave off for 5-10 minutes. This will allow the computer to reset. The charger may have interupted the signal or something.

Parking light spontaneously come on while turned off.


I guess my first question would be can you turn them off when it happens ? Most factory installed alarms would make all of the lights flash.
You could pull the fuse when you park the van until you find the problem.
