Cadillac 2008 CTS - Manual (Page 84)

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 on page 3-48.
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 3-54 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, located above
the metal base.
2. Remove the old battery. Do not use a metal object.
3. Insert the new battery, positive side facing up.
Replace with a CR2032 or equivalent battery.
4. Put the transmitter back together tightly.
