I was wanting to know where the control for the sensitivity for the stock alarm.
My alarm has recently became very sensitive.
So sensitive that if you walk pass it will go off without even touching the car.
I'm dont think everyone here has the same alarm as mine but some might.
It is the alarm that comes with the top of the line Celica here in Australia (ZR) and is an options on other Celica.
I hoping you guys can pin point where the alarm module so I dont have to pull apart my interior to find it.

Thanks

Interesting...I've never heard of factory alarms with proximity sensors. One thing you could do is listen inside the car for relays clicking when you disarm the car with the remote.

Does this factory alarm have a siren?

Yep, its has a siren.
I think its has an immobiliser as well.
