Pass-Key ® Iii - GMC Yukon Denalid Owner's Manual

Here is how to avoid setting off the alarm by
accident:
•
If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the
door key after the doors are closed.
•
Always unlock a door with the RKE transmitter.
Unlocking a door any other way will set off
the alarm.
If you set off the alarm by accident, turn off the
alarm by pressing the unlock button on the
RKE transmitter. The alarm will not stop if you try
to unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
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 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.
136
While 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 538.
If the alarm does not sound or the headlamps do
not flash, the vehicle should be serviced by
your dealer.
