Passlock - GMC 2007 Envoy Denali Owner's Manual

To avoid setting off the alarm by accident, do the
following:
•
Always lock the vehicle using the door key
after the doors are closed.
•
Always unlock a door with a key, or use the
RKE transmitter. Unlocking a door any other
way will set off the alarm.
If you set off the alarm by accident, unlock any
door with the key. You can also turn off the alarm
by pressing unlock on the RKE transmitter.
The alarm will not stop if you try to unlock a door
any other way.
Testing the Alarm
To test the alarm, do the following:
1. From inside the vehicle, lower the driver's
window and open the driver's door.
2. Activate the system by locking the doors with
the power door lock switch while the door is
open, or with the RKE transmitter.
3. Get out of the vehicle, close the door and wait
for the security light to go out.
4. Then reach in through the window, unlock the
door with the manual door lock and open the
door. This should set off the alarm.
When the alarm is set the power door unlock
switch will not work.
If the alarm does not sound when it should but the
headlamps flash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
see Fuses and Circuit Breakers on page 493.
If the alarm does not sound or the headlamps do
not flash, the vehicle should be serviced by
your dealer.

Passlock

Your vehicle has the Passlock
system.
®
Passlock is a passive theft-deterrent system that
enables fuel if the ignition lock cylinder is turned
with a valid key. If a correct key is not used or the
ignition lock cylinder has been tampered with, the
fuel system is disabled and the vehicle will not start.
During normal operation, the security light will
turn off about five seconds after the key is turned
to RUN.
