Door Locks Opening at Random

My friend has a 1999 Avalon. The door locks have started opening at andom.
I would like to do a little debugging. Does any body know where the control
module for the door locks is located?

Also, is there a separate module for the alarm system or are the two
integrated?

It seems the doors unlock at random. If the alarm is set, then the alarm sounds. To me that implies the car doesn't "think" it was the remote that
unlocked the doors.

We were sitting in his driveway last night having a cold one and every few
minutes we could hear the door locks "click". In one case, we locked all
the doors (alarm not set). In a few minutes, we heard the click and is
seems only the driver's door was unlocked. To me that means the lock
controller thought that someone unlocked the driver's door using the inside
door handle or key in the door.

The car has an aftermarket remote starter system. He has taken the car to
both the dealer and the guys that installed the remote starter. Both say
their parts check out and it must be a problem with the other's equipment.

Thanks in Advance

I guess no one knows where the control module for the door locks is located. Does anybody know of a forum where I might get the answer?

Thanks

Did your friend have a 'bypass module' installed with the remote system...it disactivates the alarm when the remote start is used.

I don't know. I'll have to look into it and get back.

Thanks
