2006 CADILLAC DTS PROFESSIONAL battery location

At times you may notice a decrease in operating range.
This is normal for any remote keyless entry system.
If the transmitter does not work or if you have to stand
closer to your vehicle for the transmitter to work,
try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-5.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System
Operation
The vehicle’s doors can be locked and unlocked, and
the trunk can be unlatched from about 3 feet (1 m) up to
60 feet (18 m) away with the remote keyless entry
transmitter.
You can also start your vehicle with the remote keyless
entry transmitter. Your remote keyless entry transmitter,
with the remote start button, provides an increased
range of operation. You can start your vehicle from an
average range of 195 feet (60 m) away. However,
the range may be less while the vehicle is running and
you may need to be closer to your vehicle to turn it
off than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter. SeeRemote Keyless
Entry System on page 2-4.

Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry 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 GM dealer. Remember to
bring any additional transmitters so they can also
be re-coded to match the new transmitter. Once your
dealer has coded the new transmitter, the lost
transmitter will not unlock your vehicle. The vehicle can
have a maximum of eight transmitters matched to it.
See RELEARN REMOTE KEY underDIC Controls and
Displays on page 3-72.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four 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.
The REPLACE BATTERY IN REMOTE KEY message
in the vehicle’s DIC will display if the remote keyless
entry transmitter battery is low. See “REPLACE
BATTERY IN REMOTE KEY” underDIC Warnings and
Messages on page 3-76for 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 remote keyless entry
transmitter, do the following:
1. Insert a at object, with a thin edge, into the notch
located below the trunk release button, and
separate the bottom half from the top half of the
transmitter.
2. Remove the old battery using a pencil or similar
object. Do not use a metal object to do this.

5. Check that the jumper cables do not have loose or
missing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+) will go to
positive (+) or to a remote positive (+) terminal if
the vehicle has one. Negative (−) will go to a heavy,
unpainted metal engine part or to a remote
negative (−) terminal if the vehicle has one.
Do not connect positive (+) to negative (−)oryou
will get a short that would damage the battery
and maybe other parts too. And do not connect the
negative (−) cable to the negative (−) terminal on
the dead battery because this can cause sparks.
6. Connect the red positive (+) cable to the remote
positive (+) terminal location on the vehicle with
the dead battery. Use a remote positive (+) terminal
if the vehicle has one.
7. Do not let the other end touch metal. Connect it to
the positive (+) terminal location of the vehicle with
the good battery. Use a remote positive (+)
terminal if the vehicle has one.8. Now connect the black negative (−) cable to the
negative (−) terminal location of the vehicle with
the good battery. Use a remote negative (−) terminal
if the vehicle has one.
Do not let the other end of the cable touch anything
until the next step. The other end of the negative (−)
cable does not go to the dead battery. It goes to
a heavy, unpainted metal engine part or to a
remote negative (−) terminal on the vehicle with
the dead battery.
9. Connect the other end of the negative (−) cable to
the negative (−) terminal location on the vehicle with
the dead battery. Your vehicle has a remote
negative (−) terminal marked GND (−).
10. Now start the vehicle with the good battery and run
the engine for a while.
11. Try to start the vehicle that had the dead battery.
If it will not start after a few tries, it probably
needs service.
