1. A method for determining a location of a digital key wallet comprising:
selecting, by a user, whether to store the digital key wallet in a cloud storage or within a secure telematics unit contained within a vehicle, wherein the digital key wallet is configured to initiate an event within the vehicle;
storing, in a backoffice server, a radio intelligence database and a rule-based vehicle pattern matrix; and
switching the digital key wallet to a fallback device based on a known location area in which communication connectivity is known, status of a communication link with the secure telematics unit, the radio intelligence database, and the rule-based vehicle pattern matrix,
wherein if the vehicle stops in an unknown location area, keep the digital key wallet in the current location regardless of communication connectivity, the unknown location area being associated with an unknown communication connectivity pattern.
