2004 CADILLAC XLR key fob battery

Battery Replacement
Under normal use, the battery in your keyless access
transmitter should last about three 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 is probably time to change the battery.
A weak battery may also cause the DIC to display NO
FOBS DETECTED when you try to start the vehicle. If
this happens, place the transmitter in the glove box
transmitter pocket with the buttons facing to the right.
Then, with the vehicle in PARK (P) or NEUTRAL (N),
press the brake pedal and the START button. Although
this will start the vehicle, it is recommended that you
replace the transmitter battery as soon as possible. The
DIC may display FOB BATTERY 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.1. Insert a coin or similar object into the slot on the
back of the transmitter and gently pry apart the
front and back.
2. Gently pull the battery out of the transmitter.
3. Put the new battery in the transmitter, positive (+)
side up. Use a battery, type CR2032, or equivalent.
4. Reassemble the transmitter. Make sure to put
it together so water will not get in.
5. Test the transmitter.

When the engine is off, press this button to place the
vehicle in ACCESSORY mode. ACCESSORY
MODE ACTIVE will display on the Driver Information
Center (DIC). This mode allows you to use things
like the radio and the windshield wipers while the engine
is off. Use ACCESSORY if you must have your vehicle
in motion while the engine is off, for example, if your
vehicle is being pushed or towed. If the door is
open while in ACCESSORY, the key in reminder chime
will sound continuously.
Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the engine is turned off:

a safety feature. To restart when you are already

The keyless access transmitter must be in the vehicle
for the ignition to work.

2. If the engine does not start and no DIC message is
displayed, wait 15 seconds before trying again.
