Abstract
Methods and apparatus are provided to dynamically configure a passive entry, passive start system to issue passive and active commands upon authentication of a remote keyless fob with a body control module in a given vehicle selected from a fleet of vehicles. In particular, a UID secret key data field is generated in the FOB data store using a fleet secret key data field and a vehicle secret key field retrieved from the BCM data store. A wakeup pattern data field stored in the FOB data store is generated with a fleet wakeup pattern data field and a master wakeup pattern data field retrieved from the BCM data store such that an approach wakeup pattern data field stored in the BCM data field is written to an approach wakeup pattern data field in the FOB data store when the remote fob is authenticated with the body control module.
