Car Alarms: Camaro Alarm, gm passlock, alarmtek

Question
QUESTION: I have 1998 Z-28 Camaro.  I think someone tried to break into it unsuccessfully one night.  Now, every time I use the remote to set the alarm, the alarm starts going off.  I tried using the key to lock/unlick the driver door, but it didn't help.  I disconnected and reconnected the battery, but that didn't help either.  The car starts and runs fine.  But, I can't set the alarm any more without it going off.  What should I do?  Thanks.

ANSWER: Please tell me what you are experiencing.

I need to determine whether it's a factory alarm
issue or, if it's an aftermarket system you are
dealing with.

Is it: Headlights flashing, car horn honking
and a worded SECURITY" light in the dash flashing?
Or,
Is it: flashing parking lights,
an LED in the dash area, and a siren
"going off"?

Let me know more on this to better
advise you on a course of action.

QUESTION: It's the factory GM alarm.  When I use the remote to lock the doors, it arms the alarm automatically.  Everything seems fine at first.  Both doors lock as they should and the alarm arms itself.  But after about 10 seconds, the horn starts honking off and on.  When I use the remote to unlock the doors and disarm the alarm, it beeps twice.

Answer
Ok, here's what's happening,
the vehicle thinks someone is trying to start
the car with the incorrect key.

If there is no aftermarket remote start in the vehicle,
then I would suggest taking it to the dealership
for repair.

Now don't confuse this. The reaction you are having IS
due to the GM PASSLOCK II system being breached & activated
or, it is malfunctioning. In either case, this is
what (in this car) is troubling you. The trouble
though is that the local mechanic at
the gas station can't help here.

Sorry, but the passlock is GM's way
of getting you coming and going.

There is no outside method other then circumventing
it momentarilly to allow remote start, which won't
fix your troubles.

Nope, this is a GM issue and has to be corrected there,
or an outside shop will charge you bukoo bucks
to replace the whole VATS. (VERY PRICEY $$$$!)

Sorry wish I could be more help, but if it's
intermittent now, then it needs they're technician,
they're factory computer diagnostics to fix it.

There will be a fee involved to reset it, but much less
then replacing the entire VATS-Passlock system.

If you do find another fix, let us all know.
This is NOT uncommon. It is GM's way of keeping
it all inhouse, security wise.

Let us know what you find out.
