Can I put a factory OEM keyless entry module into a 2001 Ford Taurus LX?

I had bought an FOB for my girlfriend's Taurus, when I tired programming it, it never went into programming mode. And yes I did it right with the turn ignition on and off 8 times. It doesn't have the keyless entry module. Can I buy another module from a different taurus and install it? (I want the standard FOB) I don't care how many wires I have to splice or the price, so don't tell me to get an aftermarket.
