Recently purchased a 93 Maxima equipped with Touchpad Entry System.

Unfortunately, I do not know the 7 digit "fixed" code (factory programmed).

Without it, system is unusable.

Nissan dealership said they could not provide the code, but could reprogram
the system at a cost of $90.

I said, no thanks.

Question: Is there any way to reprogram the system myself or, at a minimum,
retrieve the "fixed" code from the system itself, or retrieve the "fixed"
code from Nissan based on VIN?

Thanks in advance.
