Do you have the OEM alarm option or just keyless entry?
If you have an LED near the rear defog button and a siren chirp when locking or unlocking then it's the alarm, if so there is a button near the dead pedal (obviously on the drives side footwell)
Press that in for about 10-15 seconds and it should allow you to start your car
Where are you in Mass? If you have the alarm I just picked up a spare one for my 96 GT, if you aren't too far I could meet up with you and show you how to use the button to program the remote and then you could replace mine down the road (bought this one off Ebay)
PM or email me if interested
