Disclosed systems and methods provide self-service access control for rental vehicles in which a user's mobile device may be used to access rental vehicles and to determine and process payments for rental vehicle usage. A user's mobile device may be configured to receive a user-profile including one or more access rules governing a user's access rights to one or more respective point-of-entry devices associated with one or more respective rental vehicles. The user device may then provide an access key to a point-of-entry device to unlock a rental vehicle. The user device and/or an external device may then determine and process a payment for usage of the rental vehicle after the vehicle has been returned to the point-of-entry device from which it was accessed or to a different point-of-entry device. The user's mobile device may further be configured to lock and unlock point-of-entry devices that secure various vehicle accessories.
