RKE TRANSMITTER BATTERIES

The Remote Keyless Entry (RKE) transmitter case snaps open and shut for battery access. To replace the RKE
transmitter batteries:

1. Using a thin coin, gently pry at the notch in the center seam of the RKE transmitter case halves near the

key ring until the two halves unsnap.

2. Lift the back half of the transmitter case off of the RKE transmitter.

3. Remove the two batteries from the RKE transmitter.

4. Replace the two batteries with new Panasonic 2016 (if equipped with one battery, use 2032), or

equivalent. Be certain that the batteries are installed with their polarity correctly oriented.

5. Align the two RKE transmitter case halves with each other, and squeeze them firmly and evenly together

until they snap back into place.

RKE TRANSMITTER PROGRAMING

New Remote Keyless Entry (RKE) transmitters can be programed using the scan tool and the proper Diagnostic
article, if no functioning transmitter is available. The scan tool can provide confirmation that the Controlled
Area Network (CAN) is functional, and that all of the electronic modules are sending and receiving the proper
messages on the CAN data bus.

The following procedure can be used as long as one functioning transmitter is available:

1. Turn ignition to the RUN position (allow ignition chimes to stop).

2. Using any original (working) transmitter, press the UNLOCK button for 4 to 10 seconds.

3. Within the specified 4 to 10 seconds, continue pressing the UNLOCK button and press the PANIC button

for 1 second, and release both buttons (a chime will sound to indicate that the transmitter programming
mode has been entered - allow 3 seconds for chime to sound).

4. Press LOCK and UNLOCK buttons simultaneously for 1 second and release.

5. Press and release any button on the same transmitter and a chime will sound after successfully

programming the transmitter.

6. Repeat steps 4 to 6 to program additional transmitters.

7. Turn ignition to the OFF position. Transmitter programming mode will discontinue after 60 seconds. All

transmitter programming must be completed within time specified.

RANGE

Normal operation range is up to a distance of 3 to 7 meters (10 to 23 ft.) of the vehicle. Range may be better or
worse depending on the environment around the vehicle.

TAILGATE CYLINDER LOCK SWITCH

DESCRIPTION

TAILGATE CYLINDER LOCK SWITCH

The tailgate cylinder lock switch is integral to the key lock cylinder inside the tailgate. The tailgate cylinder
lock switch is a normally-open momentary switch that is hard wired directly to the Totally Integrated Power
Module (TIPM), and closes a path to ground through an internal resistor when the lock cylinder is rotated to the
unlock or lock position.

The tailgate cylinder lock switch cannot be adjusted or repaired.

OPERATION

2007 Dodge Nitro R/T

2007 ACCESSORIES AND EQUIPMENT Power Locks - Service Information - Nitro

TAILGATE CYLINDER LOCK SWITCH

The tailgate cylinder lock switch is actuated when the key is inserted in the lock cylinder and turned to the
unlock or lock position. The tailgate cylinder lock switch closes a path to ground through an internal resistor for
the Totally Integrated Power Module (TIPM) when the tailgate key lock cylinder is in the lock or unlock
position, and opens the ground path when the lock cylinder is in the neutral position. The TIPM reads the switch
status, then sends the proper switch status messages to other electronic modules over the Controlled Area
Network (CAN). The tailgate cylinder lock switch unlock status message is used by the TIPM as an input for
Vehicle Theft Security System (VTSS) operation and to tell the TIPM to lock or unlock the tailgate. There is no
mechanical linkage between the tailgate key cylinder and the latches.

DIAGNOSIS AND TESTING

TAILGATE CYLINDER LOCK SWITCH

1. Disconnect and isolate the battery negative cable.

2. Remove tailgate trim panel. Refer to REMOVAL .

3. Disconnect tailgate cylinder lock switch harness connector.

4. Using a ohmmeter, test for resistances as shown in the Tailgate Cylinder Lock Switch Table.
