How do I replace the ECM on my Altima?

I have a 2000 Altima GXE that needs replaced and the dealer wants $700. Where do I find the part # and how can I replace it myself?

You can get the part number from the dealer. Just go to the parts department and kindly ask for the part number. To replaced it, just unbolt the old one and install the new one. Just remember to disconnect the car battery after you install the new one.

There is one BIG problem, the keys needs to be reprogram to the ECM after the installation.
