I don't know a lot about this system, but perhaps the following description from the '04 FSM will help, and may be a springboard for discussion with others who know more about it than I do:

SKIS INDICATOR LAMP
DESCRIPTION
The Sentry Key Immobilizer System (SKIS) uses the Vehicle Theft Security System (VTSS) indicator LED to give an indication when the SKIS is faulty or when the vehicle has been immobilized due to the use of an invalid ignition key. The LED is controlled by the BCM based upon messages received from the Sentry Key Immobilizer Module (SKIM). The VTSS/ SKIS indicator LED is hard wired directly to the BCM.

OPERATION
The SKIM sends messages to the BCM to turn the LED on for about three seconds when the ignition switch is turned to the ON position as a bulb test. After completion of the bulb test, the SKIM sends bus messages to the BCM to keep the LED off for a duration of about one second. Then the SKIM sends messages to the BCM to turn the LED on or off based upon the results of the SKIS self-tests. If the VTSS indicator LED comes on and stays on after the bulb test, it indicates that the SKIM has detected a system malfunction and/or that the SKIS has become inoperative. If the SKIM detects an invalid key when the ignition switch is turned to the ON position, it sends messages to the BCM to flash the VTSS indi- cator LED.

The SKIM can also send messages to the BCM to flash the LED and to generate a single audible chime tone. These functions serve as an indication to the customer that the SKIS has been placed in its “Customer Learn” programming mode. See Sentry Key Immobilizer System Transponder Programming in this section for more information on the “Customer Learn” programming mode.

The VTSS indicator LED is housed in the Auto- matic Temperature Control (ATC) Sun Sensor located in the instrument panel top cover. Refer to Group 8E - Instrument Panel and Systems for service of ATC Sun Sensor. If the VTSS indicator LED comes on and stays on after the bulb test function, diagnosis of the SKIS should be performed with a DRB III􏰀 scan tool and the proper Body Diagnostic Procedures Manual.

The "Transponder" that's referred to regarding this problem is the chip in the actual key and it's corresponding antenna ring that's part of the SKIM module. Your Remote Keyless Entry or RKE fob is separate from the key and isn't involved with this problem.

For all faults except transponder faults and VTSS
LED remains on steady. In the event of a transponder
fault the LED flashes at a rate of 1 Hz (once per
second).
If a fault is present the LED will remain on
or flashing for the complete ignition cycle. If a fault
is stored in SKIM memory which prevents the
system from operating properly,
the PCM will allow
the engine to start and run (for 2 seconds) up to six
times. After the sixth attempt, the PCM disables
the starter relay until the fault is corrected.

If it's blinking then either the key or SKIM module. Need to get the codes read.

Might be as simple as getting a new Sentry key cut & programmed. If he has a 2nd key....try using that one. If only 1 Sentry key then see beginning of first sentence.

The What color is the plastic head of your Ignition key? It should be gray in color and not black. If it's not the original key and it's an aftermarket replacement that was cut and programmed for your car, those keys are known to eventually go bad. They'll either stop functioning completely or gradually degrade and quit functioning.

The only way to know what's going on is to get the codes read. A competent locksmith should be able to verify the key and be able to cut/program a new at much less cost than the dealer. Otherwise it's off to the Dealer you go hi-ho and be prepared to pay a princely sum!

The title for the tests will be TRANSPONDER COMMUNICATION
FAILURE.
When Monitored and Set Condition:
TRANSPONDER COMMUNICATION FAILURE
When Monitored: At ignition on and during Key Programming Mode.
Set Condition: When the SKIM does not receive a transponder response after 8 consecutive
transponder read attempts within 2.0 seconds.
TRANSPONDER CYCLIC REDUNDANCY CHECK (CRC) FAILURE
When Monitored: At ignition on and during Key Programming Mode.
Set Condition: When 5 consecutive transponder signal transmissions are sent to the
SKIM with the correct message format but with invalid data.
TRANSPONDER ID MISMATCH
When Monitored: At ignition on and during Key Programming Mode.
Set Condition: When the transponder ID read by the SKIM does not match any of the
transponder ID’s stored in the SKIM’s memory.
TRANSPONDER RESPONSE MISMATCH
When Monitored: At ignition on and during Key Programming Mode.
Set Condition: When the transponder’s crypto algorithm result fails to match the SKIM’s

Sounds like you might have just a factory alarm and not SKIM then?

Something like the Optional Chrysler EVS II Security System you could buy from the dealer.

When you use your fob to lock the door and arm the alarm do you hear a double chirp or does the regular horn honk?

Also where is where is the red LED located exactly in your car. Is it on top of the dash near the center close to the windshield or somewhere else?

The horn beeps... red led is right on top of the area where you turn on lites for the car, on left side

Sounds like you have an aftermarket alarm installed. I really can't hep you much on that. Did you buy the car used with that already installed?

Like I said above. Sounds like it's an aftermarket alarm due to your description of the Red LED being located above the headlight switch. All LH factory alarms have the LED up on top of the dash at the center near the windshield.

Can't really help you any further. Maybe take it to a local stereo/alarm installation shop and see what they say.
