2005 CHEVROLET TRAIL BLAZER Owners Manual

Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter will not
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it’s probably time to change the battery.
The Driver Information Center (DIC) will display a KEY
FOB # BATTERY LOW message when the transmitter
battery is low.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.To replace the battery in the remote keyless entry
transmitter do the following:
1. Insert a thin coin in the slot between the covers
of the transmitter housing. Gently pry the
transmitter apart.
2. Remove and replace the battery with a three-volt
CR2032 or equivalent battery.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.

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.
You can use the remote keyless entry transmitter.
You can use your key to unlock your door from
the outside.
You can lock or unlock the door from the inside by sliding
the manual lever forward or rearward. When the door is
unlocked, you can see a red area on the lever.
The manual lever on each door works only that
door’s lock.
