antitheft problem

Hi.
I own a '95 cirrus lx 2.5.
I don't have the original oem keyless remote. The car has an aftermarket
starter installed which also locks/unlocks the doors.
The keys that I have for the cars don't work on the front doors, but work on
everything else (trunk and engine). It never bothered me since I've always
used the remote starter keyless remote.
Problem is that somehow or something triggered the antitheft or the panick
mode on the car. (when it happened the car was parked at work in a fairly
small paking lot).
It starts, runs for 4-5 seconds then stops. Light are flashing in sync with
the horn.
Since I can't do the obvious and use my keys to unlock the front doors and
therefore disable the alarm or the panic mode, my question is where is the
oem antitheft and/or keyless remote modules located on the '95 cirrus lx?
I've searched and looked, but no luck. I've completly uninstalled the
aftermarket starter and still no luck. I've unplugged the battey and the
computer for about 12 hours and still no luck, the antitheft or the panick
mode is still on when I reconnect everything.
Please, if somebody knows how to fix this or where the modules are located,
let me know. I've been on this for weeks.
thanks.

 

sound like you have a alarm remote start all rolled into one unit
i would take it to a ziebert store or auto one and see if they can show ya how
to use it( not trying to dis ya)
