The Wireless Ignition Node (WIN) controls the Vehicle Theft Security System (VTSS), Remote Keyless Entry (RKE). When a Powertrain Control Module (PCM) is in need of replacement, perform the following steps in order:
The secret key is an ID code that is unique to each WIN. This code is programmed and stored in the WIN, the PCM, and each ignition key transponder chip. When the PCM or WIN is replaced, it is necessary to program the Secret Key Code into the new module using a diagnostic scan tool. Follow the programming steps outlined in the diagnostic scan tool for PCM REPLACED, WIN REPLACED, or TIPM REPLACED under MISCELLANEOUS FUNCTIONS for the WIRELESS CONTROL MODULE menu item as appropriate.
When an PCM and the WIN are replaced at the same time, perform the following steps in order:
Each FOBIK has a unique ID code that is assigned at the time the key is manufactured. When a key is programmed into the WIN, the module learns the transponder ID code and the transponder acquires the unique Secret Key ID code from the WIN.
The Fob with Integrated Key (FOBIK) cannot be rotated to the LOCK position, allowing it to be removed from the ignition switch also referred to as the Wireless Ignition Node/WIN. The automatic transmission or transaxle is shifted mechanically through a cable from the gearshift lever mechanism to the transmission or transaxle valve body. A gated park switch is physically located on and integral to the gearshift lever mechanism and is hard wired directly to the WIN. The gated park switch is a simple plunger-like actuated open or closed contact switch that could be considered redundant to the Transmission Range Sensor (TRS) except that it monitors the position selected with the gearshift lever, while the TRS monitors the position or gear of the transmission or transaxle that is actually engaged. A damaged or improperly adjusted gearshift cable could result in a different gear being engaged than that which is selected. The WIN uses the gated park switch input to control an internal key lock solenoid, which controls whether the FOBIK can be rotated to the LOCK position. When the gearshift lever is not in the PARK position, the gated park switch is a closed circuit, the key lock solenoid is energized and the FOBIK cannot be rotated to the LOCK position for removal.
Uh, I am just the car owner without access to any of the tools you describe.
Is there no simple sequence such as sitting in the driver's seat, pressing certain buttons at certain times in a certain sequence to get the car to re-remember a key that used to work?
Using special tool 9001, first test to ensure that the transmitter is functioning. Typical testing distance is 2.5 centimeters (1 inch) for Asian transmitters and 30.5 centimeters (12 inches) for all others. To test, position the transmitter as shown. Press any transmitter button, then test each button individually. The tool will beep if a radio signal strength that lights five or more LED's is detected. Repeat this test three times. If transmitter fails any of the test, refer to the Diagnostic Procedures manual.
To replace the FOBIK transmitter battery:
This design is a clam shell design whereby both halves are split apart.
What I need is what comes after "Test FOBIK operation" and that test results in failure.
How do I get the car (WIN?) to recognize the key as valid? Remember, I'm just the car owner and have no access to the diagnotic tools.
I decided to just bite the bullet and get a new wireless key from the dealer ($240 plus a $47 programming charge). I could buy a decent laptop for that amount of money!
Truly rediculous that Chrysler won't allow certified technicians to tell customers how to re-program a key. Talk about a strangle-hold.
