I had a similar problem with my '87.
The VATS can not like the "chip" (it's really just a resistor with one of about
a dozen values)
because it gets a poor connection. If the VATS doesn't like the "chip" in the
key, you gotta wait
five minutes before it will start. I'd suggest spending those five minutes
puttng the key in and out
to clean up the contacts.
I've seen VATS bypass widgets in the MidAmerica catalog.
