2006 GMC SIERRA keyless

Always unlock a door with the remote keyless entry
transmitter.
If you set off the alarm by accident, turn off the alarm by
pressing unlock on the remote keyless entry transmitter
or by placing the key in the ignition and turning it to
START.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, activate the system by
locking the doors with the remote keyless entry
transmitter.
2. Wait for the security light to go out.
3. Unlock the door with the manual door lock and
open the door. This should set off the alarm.
4. Turn off the alarm by pressing unlock on the remote
keyless entry transmitter or by placing the key in
the ignition and turning it to START.
If the alarm does not sound when it should, but the
vehicle’s headlamps ash, check to see if the horn
works. The horn fuse may be blown. To replace the
fuse, seeInstrument Panel Fuse Block on page 5-124
andUnderhood Fuse Block on page 5-127.
If the alarm does not sound or the vehicle’s headlamps
do not ash, see your dealer for service.
