Abstract

A system and method for estimation method for determining a location of a vehicle digital key wallet includes selecting, by a user, whether to store a digital key wallet in a cloud storage or within a secure telematics unit contained within a vehicle. The digital key wallet is used to initiate an event within the vehicle. A backoffice server stores data including a radio intelligence database and a rule-based vehicle pattern matrix. The digital key wallet is switched to a fallback device based on the status of a communication link with the secure telematics unit, the radio intelligence database, and the rule-based vehicle pattern matrix.
