2007 Camry LE - door locking mechanism problem

[TireHead99]

Hi guys, basically my car has a problem where the passenger side doors won't unlock. I can't unlock the passenger doors by pressing twice with the key, or unlock with the control panel from the driver side. I was told that the computer module that is responsible for handling it needs to be replaced. I was wondering if anyone happens to know where I can buy this part and the name of it? any idea how much it costs?


Thanks for any help greatly appreciated.
