Remote Keyless Entry Module: Operation
WARNING: This page is about a different car, the 2004 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.
Whenever the vehicle battery power is interrupted, the Remote Keyless Module (RKE) Module will retain all vehicle access codes in its memory. When replacing or adding a key fob transmitter (maximum of 4) a DRB III(R) scan tool is required to program the RKE Module to accept the new Vehicle Access Code if a customer owned transmitter is not available.
If a functioning transmitter is available, see STANDARD PROCEDURE .
