Remote Keyless Entry

WARNING: This page is about a different car, the 2004 Dodge Grand Caravan, 2004 Dodge Caravan, and 2004 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.

The RKE transmitter uses radio frequency signals to communicate with the SKREEM module. The SKREEM is on the PCI bus. When the operator presses a button on the transmitter, it sends a specific request to the SKREEM. In turn, the SKREEM sends the appropriate request over the PCI bus to the following:

Integrated Power Module (IPM) - to activate the park lamps, the headlamps and the horn for the horn chirp.
Power Liftgate Module (PLGM) - to control the liftgate lock and unlock functions.

After pressing the lock button on the RKE transmitter, all of the door locks will lock, the illuminated entry will turn off (if all doors are closed) and the vehicle theft security system (if equipped) will arm.

Pressing the unlock button one time will unlock the driver door, or all doors based on the customer programmable feature enabled, the illuminated entry will turn on the courtesy lamps and the vehicle theft security system (if equipped) will disarm. Pressing the unlock button a second time, the remaining door locks will unlock.

If the vehicle is equipped with the memory system, the memory message will identify which transmitter (1 or 2) sent the signal.
