General Information

SECURED ACCESS mode is not required to check programmed status of key. If PCM is replaced, a unique secret key data must be transferred from Sentry Key Immobilizer Module (SKIM) to Powertrain Control Module (PCM). This procedure requires SKIM to be placed in SECURED ACCESS mode using 4-digit Personal Identification Number (PIN) code.

SKIM will only remain in secured access mode for 60 seconds. If incorrect unique PIN is entered 3 times, SKIM will be locked for one hour. To exit lock out mode, turn ignition switch to RUN position continuously for one hour. Ensure all accessories are turned off. Monitor battery state and connect battery charger is necessary. To program sentry keys using "customer programming method" requires 2 valid sentry keys. See SENTRY KEYS  .
