Cadillac 2010 DTS - Manual (Page 114)

Programming Transmitters
to the Vehicle
Only RKE transmitters programmed to the vehicle will
work. If a transmitter is lost or stolen, a replacement can
be purchased and programmed through your dealer.
When the replacement transmitter is programmed
to the vehicle, all remaining transmitters must also
be programmed. Any lost or stolen transmitters no
longer work once the new transmitter is programmed.
Each vehicle can have up to eight transmitters
programmed to it. See RELEARN REMOTE KEY
under DIC Operation and Displays on page 4‑61.
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 4‑66 for additional
information.
Notice: When replacing the battery, do not touch
any of the circuitry on the transmitter. Static from
your body could damage the transmitter.
To replace the battery:
1. Separate 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. Reassemble the transmitter.
