Question about 2006 Toyota Prius
Something you need to be aware of here is that the factory alarm on your prius only detects doors, this meaning if any of the 4 doors, the hood or the back hatch are opened then it detects this and monitors the door positions, if the alarm is armed and a door is either unlocked or opened unauthorized then it sets this alarm off. You can jump on the roof or ram the car with a dump truck and it will not set the alarm off, the factory alarm does NOT detect impact, it only detects door lock/unlock and door open/close. The only way this alarm will go off (other then if you press the red panic button on the remote) is if a door is either unlocked or opened without the use of a key/remote.
The door entry switches would need to be played around with here and a scan tool with data lists are needed, I have seen some cases where the bolt that holds the door switch to the body is loose and causes this.
The Factory Security system has many customizable features that can be turned on or off or adjusted. The Dealer has the ability to do this for you. I would first have them diagnose why it is setting prematurely. Perhaps the sensitivity is set too high. Have them make the adjustments and see how it goes.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
