Welcome to Allpar. If the ARKEM module is replaced, it will need the dealer DRB III to configure and program it to your transmitters.
NOTE: When replacing a faulty RKE Module, the replacement module must be configured with the DRB lllscan tool for proper operation. Refer to Vehicle Theft/Security Systems, Switching Operat- ing Modes/Configuring a New Module under Service Procedures. Additionally, all transmitters must be reprogrammed to the new RKE module.
