key HUMMER H2 2006 User Guide

To replace the battery in the keyless entry transmitter,
do the following:
1. Insert a thin object, such as a coin, in the slot
between the covers of the transmitter housing
near the key ring hole. Remove the bottom
by twisting the coin.
2. Remove and replace the battery with a
three-volt CR2032 or equivalent battery, positive (+)
side up.
3. Align the covers and snap them together.
4. Resynchronize the transmitter. See
“Resynchronization” following this information.
5. Check the operation of the transmitter.Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The transmitter
does not send the same signal twice to the receiver. The
receiver will not respond to a signal that has been
sent previously. This prevents anyone from recording
and playing back the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and press and hold the lock and unlock
buttons on the transmitter at the same time for
15 seconds. The door locks should cycle to conrm
synchronization. If the locks do not cycle, see your
dealer for service.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle will not open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors are not locked. So,
wear safety belts properly and lock the
doors whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock your vehicle.
To unlock the door from the outside, use the keyless
entry system or the key.
To unlock or lock the door
from the inside, slide the
manual lever forward
or rearward.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle is equipped with a content theft-deterrent
alarm system.
With this system, the
security light in the
instrument panel cluster will
ash as you open the door
if your ignition is off.
This light reminds you to activate the theft-deterrent
system. Here is how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The security
light will illuminate to inform the driver the system is
arming. If a door is open when the doors are
locked, the security light will ash.
2-21

3. Close all doors. The security light should go off
after about 30 seconds. The alarm is not armed
until the security light goes off.
If the delayed locking feature is turned on, the
theft-deterrent system will not start the arming
process until the last door is closed and the delay
timer has expired. SeeDelayed Locking on
page 2-9.
If a locked door is opened without the key or the remote
keyless entry transmitter, the alarm will go off. The
headlamps and parking lamps will ash for two minutes,
and the horn will sound for 30 seconds, then will turn
off to save the battery power. You can choose different
feedback options for the alarm. SeeDIC Vehicle
Customization on page 3-55.
Remember, the theft-deterrent system will not activate if
you lock the doors with the vehicle’s key or use the
manual door lock. It activates only if you use a power
door lock switch with the door open, or with the remote
keyless entry transmitter. You should also remember
that you can start your vehicle with the correct ignition
key if the alarm has been set off.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 keyafterthe doors are closed.
Always unlock a door with a key, or use the remote
keyless entry 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 remote keyless entry 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
power door lock switch while the door is open, or
with the remote keyless entry 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.
2-22

While the alarm is set, the power door unlock switch is
not operational.
If the alarm does not sound when it should but the
headlamps ash, check to see if the horn works. The
horn fuse may be blown. To replace the fuse, see
Instrument Panel Fuse Block on page 5-116and
Underhood Fuse Block on page 5-119.
If the alarm does not sound or the headlamps do not
ash, the vehicle should be serviced by your dealer.
Passlock®
Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock
®is a passive theft-deterrent system. Passlock®
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 is tampered with, the fuel system is
disabled and the vehicle will not start.During normal operation, the security light will turn off
approximately ve seconds after the key is turned
to RUN.
If the engine stalls and the security light ashes, wait
about 10 minutes until the light stops ashing before
trying to restart the engine. Remember to release
the key from START as soon as the engine starts.
If the engine does not start after three tries, the vehicle
needs service.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the
engine off. However, your Passlock
®system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
®at this
time. You may also want to check the fuse. See
Instrument Panel Fuse Block on page 5-116and
Underhood Fuse Block on page 5-119. See your dealer
for service.
In an emergency, call the Roadside Assistance Center.
