Anyone know how to adjust the sensitivity? On my cousins 1997 Grand Prix GT it goes off with the slightest bump, but on my 1999 it doesn't go off -period. Tried the open windows thing and that didn't even set it off.

Martin, i called the dealer today and asked about this...of course no one knew...

you should have the alarm light up on dash board right?? the door trick should work.. roll down the window.. use the FOB and lock all doors... wait ( and have a smoke if you're a smoker like me to kill some time cause I think the system doesn't actually arm right away ) then reach in.. unlock that one door manually.. and open the door .. it should go off.. as for sensetivity.. I don't think there'* any external sensor/motion on stock alarm.. it senses by the internal light when door become ajar to my knoweldge.. I think buddy with 97 may have aftermarket .. just my 2 and ahalf make no cents idea..

Correct. There is no 'sensitivity' adjustment, as there is no shock sensor. Make sure you use the MANUAL lever next to the entry handle. Not the power unlock button on the door handle.

Lock it with the fob walk away for like 15-20 minutes, and pull on the handle inside and then outside.

You may not have any security system.

It'* standard equipment on an SSEi. Optional on the SSE.

My SE has a factory alarm on it. Mine only works like this. Doors locked and you pull up on the handle or pop trunk lid it goes off. There is like a 10sec time span there before it goes off. Also after car is turned off the ignition becomes dead until you unlock the car agian even though the door are unlocked( Gets a bit annoying).The worst thing about this hole system is that if the windows are down and you pull the door handle it goes off but you can disarm it by the unlock button on the door panel. To me you should not be able to do that. It should only disarm with the key fob only. well that is how my stock alarm work so i hope that helped you out some.

Y'know, I've read your description several times, but it doesn't sound like the factory alarm system at all, unless they changed its functionality dramatically from '93 to '94. Did you buy this car new? Is it possible that someone has installed an aftermarket box in it? After all, you're right that you should not be able to cancel the alarm simply by pressing the interior door unlock button, nor does the '93 system use a 10-second delay when there is an intrusion, nor does it trigger if you pop the trunk, nor does it kill the ignition until you... what, lock the car and unlock it again? That part of your description was the strangest part of all; none of this sounds like factory system behavior.
