CHEVROLET Tahoe - Manual (Page 118)

Battery Replacement
Under normal use, the battery in the RKE
transmitter should last about four years.
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 is probably time to change the battery.
The REPLACE BATTERY IN REMOTE KEY
message in the vehicle’s DIC will display if the
RKE transmitter battery is low. See “REPLACE
BATTERY IN REMOTE KEY” under DIC Warnings
and Messages on page 270 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 do
the following:
1. Insert a flat object with a thin edge into the
notch on the side of the transmitter and
separate the bottom half from the top half.
2. Remove the old battery, but do not use a
metal object to do this.
