Pretty sure it's in the trunk, by the battery 
Like I said... pretty sure it's in the trunk, by your battery.. take off those plastic covers and you will see it.Oh you mean the transponders? I'm actually looking for the main module that those transponders are connected to. Like when you get an aftermarket car alarm, there is a main module that is connected to the locking system of the car. Or is the main module I'm looking for is the ECU itself?
I need to know because I need to find out the trigger where the Fast Key system detects if the key is at the "ACC" or "ON" position, so I can disable it. So I can lock/unlock the car with the FOB even if the engine is running.
