Hello and thank you for using just answer!
Which TDS system do you have? Is the remote kinda banana shaped or square?
It has a toyota label on the remote. Remote is rectangular and black. Three buttons:
2 on top from left to right: "Lock" and "Unlock"
1 on bottom: "Panic"
The ECU looks just like the one I pictured above.
If the dealer put it on then it is probably above the carpet, if this was port installed it is likely UNDER the carpet there. This will be the only component under the driver seat on the floor, the old camrys are very basic and simple so there is nothing else down there.
You would need to unplug the controller and then follow the wiring up under the driver dash, some of these have a starter disable so the wiring for this controller would need to be disconnected from the ignition switch under the dash in that case.
Your remote should look like this correct?
ok.....did some deeper digging here....there was one other rare remote on this year, is this the one:
No I have not given up. The system you have here is somewhat integrated to the car then, if the alarm is going off for no reason then one of the 4 door position switches is detecting that one of the car doors is being opened.
The system layout is like this:
So in this case the wireless door lock ECU that controls the system is under the dash between the driver side and the center console.
