Cal. Civ. Code § 1939.37

A rental company is not subject to the requirements of Section 14608 of the Vehicle Code if the rental is subject to the terms of a membership agreement that allows the renter to gain physical access to a vehicle without a key through use of a code, key card, or by other means that allow the vehicle to be accessed at a remote location, or at a business location of the rental company outside of that location’s regular hours of operation.
