Where is the keyless entry control module on 2004 Mazda 3
 

I am having problems with my keyless entry. I thought originally it was the fob so I purchased a new one and now can not get it to program. I go through all the steps in the programing process and the car does not respond like all the instructions say it will. It goes into a programming mode but the instructions say after a series of turning the key on and off 3 times and opening and closing the door 3 times the door should lock and unlock indicating it is time to press the buttons on the fob to program it. However the after doing the sequence the door does not lock and unlock. It just sets there. I don't know what to do except check the module. Does anyone have suggestions?? Or know where the module is so I can check it?

Thanks

The KEU is in the headliner just behind the maplights.
