Battery Replacement - Hummer 2008 H2 Owner's Manual

Matching Transmitter(s) to Your Vehicle
Each RKE transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a transmitter
is lost or stolen, a replacement can be purchased
through your dealer/retailer. All transmitters need to be
re-coded to match the new transmitter. The lost
transmitter will no longer work after the new transmitters
are re-coded. The vehicle can have a maximum of
eight transmitters matched to it. See "Relearn Remote
Key" under DIC Operation and Displays (Using DIC
Buttons) on page 3-49 or DIC Operation and Displays
(Using Trip Odometer Reset Stem) on page 3-54
for instructions on how to match RKE transmitters to
your vehicle.

Battery Replacement

Replace the battery if the REPLACE BATTERY IN
REMOTE KEY message displays in the DIC. See
"REPLACE BATTERY IN REMOTE KEY" under DIC
Warnings and Messages on page 3-56 for additional
information.
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 RKE transmitter:
1. Separate the halves of the transmitter with a flat,
thin object inserted into the notch on the side.
2. Remove the old battery. Do not use a metal object.
3. Insert the new battery, positive side facing down.
Replace with a CR2032 or equivalent battery.
4. Put the transmitter back together tightly.
