Hidden module preventing car to start
I Purchased a 2002 maxima that can only be started by pressing a button on an aftermarket key fob while the ignition is on....I searched everywhere on the car looking for a module (under the dashboard, rmeoved the glove box..etc...). Did not find any module of an aftermarket alarm system. Anyone have an idea what is going on here..thanks...

I've never seen anything like this. Does the starter crank the engine?
It could be something under the hood interrupting the wire from the ignition switch to the inhibit relay or to the starter itself.

The key fob does not have one single marking on it! None.

Well, it looks like your predecessor's after-market system is one of the better theft-prevention gizmos out there!

Anything is possible, but this is highly unlikely. The BCM is a microprocessor controlled module, so someone would have to analyse the program for the microprocessor and then modify it. A lot of time consuming work.
Another point to consider is that if you have to press a button on the key, there has to be a receiver somewhere to pick up the signal that the key sends out. With all the searching you have done, it must be very cleverly disguised. There could be something that looks like a relay that has been added among the real Nissan relays.

It doesn't crank at all..when you turn the key nothing happens, only a click from a brown factory relay near the glove box..To get it to crank, I put the key in the ignition on position, press a button on the mystery fob and then turn the key over.

I would check the starter relay or anything attached to wires that shouldn't be there.
