Sentry Key Immobilizer Module Replacement/System Initialization

The Sentry Key Immobilizer Module (SKIM) Replacement and System Initialization Process can be summarized by the following:
1. Obtain the vehicle's unique PIN number assigned to it's original SKIM module from either the vehicle's invoice or from Daimler Chrysler's Customer Center.
2. With the DRB select "Theft Alarm " "Skim " "Miscellaneous." Select "SKIM Module Replaced" and the DRB will prompt you through the following steps.
3. Program the unique 4 digit PIN number into the SKIM's memory.
4. Program the vehicle's VIN number into the SKIM's memory.
5. Program the country code into the SKIM's memory (U.S.).
6. Transfer the vehicle's unique Secret Key data from the PCM. This process Will require the SKIM module to be in secured access mode. The PIN number must be entered into the DRB before the SKIM Will enter secured access mode. Once secured access mode is active the SKIM will remain in that mode for 60 seconds.
7. Program all customer keys into the SKIM's memory. This requires that the SKIM be in secured access mode. The SKIM module will immediately exit secured access mode after each key is programmed. Note: Secured access mode is not required to query the programmed status of the key

NOTE 1: IF A PCM IS REPLACED THE UNIQUE SECRET KEY DATA MUST BE TRANSFERRED FROM THE SKIM MODULE TO THE PCM. THIS PROCEDURE REQUIRES THE SKIM TO BE PLACED IN SECURED ACCESS MODE USING THE FOUR DIGIT PIN CODE.

NOTE 2: IF THREE ATTEMPTS ARE MADE TO ENTER SECURED ACCESS MODE USING AN INCORRECT PIN SECURED ACCESS MODE WILL BE LOCKED OUT FOR ONE HOUR. TO EXIT THIS LOCK OUT MODE LEAVE THE IGNITION SWITCH IN THE RUN POSITION CONTINUOUSLY FOR ONE HOUR. (ENSURE ALL ACCESSORIES ARE TURNED OFF. ALSO MONITOR THE BATTERY STATE AND CONNECT A BATTERY CHARGER IF NECESSARY).

To program Sentry Keys using the "customer programming" method which requires two valid Sentry Keys refer to either the owner's manual or service procedures.
