They found it to be a "black box" with this labelled on it:
P-X-4
A04
03296
How do I disable the alarm so that it won't auto-arm itself when i close the doors? I need to prevent it from going off on the mechanics when they do jobs that require them to leave the key in the ignition. How do I set it to the supposed "valet mode"? No one knows how to control it. Do You? . . . . .

The remote seems fairly generic: black, with a lock and unlock button, and an asterisk and pound button. The store told me that probably the dealer back in the early 90s put a cheap alarm into the car. I've figured out (well the store did from their own general experience) how to both unlock and arm the car with the chirp muted which i didn't know before (requires me to press all four buttons in a certain sequence), but completely disabling it at my command, I don't know how to do. Any suggestions?
Because I have hope that I don't have to replace this alarm by buying a complete new one. I just need to figure out how to control it.
Thanks in advance.
