For a '95:
Operation
You don’t have to doa nything for PKE to work when
the passive feature is on. Just walk toward your vehicle
with the PKE transmitter, and the system will
automatically disarm your theft-deterrent system and
unlock the doors. If it’s dark enough outside, your
interior lamps will come on.
If you move out of range, the PKE system will:
1. Lock the doors after five seconds.
2. Arm the theft-deterrent system.
3. Sound the horn to let you know the doors are locked.
4. Turn off the interior lamps.
You can also use the buttons on the transmitter. Press
DOOR to open the passenger’s door or HATCH to open
the hatch. The HATCH button will only work when the
ignition is off.
The system has a feature that makes it difficult for you
to lock your keys in your vehicle. If you leave your keys
in the ignition and lock the doors, the system will unlock
the doors as soon as they are closed. If you leave the
keys in the ignition and move away with the transmitter,
the doors still will not lock. You should notice that the
horn doesn’t sound and return to get your keys.
The system will allow you to lock your keys in the
vehicle if you didn’t leave them in the ignition. You
should, however, be able to use the transmitter to get
them out. After 26 seconds of no motion, the transmitter
shuts down to save tbhaet tery. Wait about 30 seconds,
then rock the vehicle. The transmitter should “wake up”
and unlock the doors.
This system can’t guarantee that you’ll never be locked
out of your vehicle. If the battery is low or if the
transmitter is in a place where the signal can’t get to the
antenna, it won’t unlock the doors. Always remember to
take your keys with you.
PKE Settings
You can use the system fobr oth doors or just the
driver’s door, or you can turn the system off.
To change door settings:
1. Put the ignition key in the ignition, but don’t turn it
2. Press DOOR on the transmitter until thed oor locks
on.
cycle (about two seconds).
To turn the system off:
1. Take the ignition key out of the ignition.
2. Press DOOR on the transmitter until the door locks
cycle (about two seconds).
To turn the system back on, just repeat the steps.
To check that the system is off, turn on the ignition. The
PASSIVE KEYLESS ENTRY light on the Driver
Information Center should not come on. If the light does
come on for as econd or two, thent he PKE system is
still on.
You can also check whether the system is on or off by
closing the dooar nd walking away with the keys and
transmitter. If the doors lock, the system is on.
If you are working around your vehicle and keeping
your keys with you, you might want to turn the PKE
system off. If you don’t, the transmitter will keep
locking and unlocking your doors.

 

What about a 84 vette shouls have mentioned that.:bang head:

 

Don't know for an 84, for an 85 (maybe it is the same):

After the ignition is turned off the system may be armed at either opened ddor by:
Activating the electric door lock switch to the lock position or
Sliding the door lock lever on both doors to the lock position. When the last door is closed, the system is armed.

The system is disarmed by unlocking either door with the key or by turning the ignition on. Alarm shutdown is accomplished only by unlocking the door with the key.
If the driver wants to prevent arming the system after using the "door lock" swithc, the switch can be moved to the unlock postiion before closing thw doors. He amy also cancel the arming process by retating the ignition switch to the "ON" position, then back to lock. Rotating the ignition switch will not cancel the alarm once it is activated.
The doors may be locked mecanically using the door key without arming the system.The door key will disarm and deactivate the system. The ignition key in the ignition lock can only disarm the system (before the alarm is activated).

Once the alarm has been activated, the starter interupt will be energized and the alarm will continue to operate for a period of three to seven minutes. At the end of the time period, the alarm will automatically shut off to conserve battery power and, if the locks have not been damaged, the system will rearm itself. However, once the system has been activated, the starter interrupt ramain energized until the proper disarming sequence is initiated.
