Smartphone Key Fob Programming With Secure Cloud Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing keyless remote devices require intervention from car dealers or locksmiths for programming, which is cumbersome and costly, and there is a need for a user-friendly, secure, and cost-effective method to program new vehicle fobs without such intervention.
Innovation Solution
A smart platform that includes a programmable remote transmitter (ARK) designed for easy programming via a smartphone app, utilizing cloud-based services to communicate with a vehicle's onboard computer, allowing users to reprogram the fob interface and transmit commands securely without dealer intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user programming of vehicle fobs is enabled without dealer intervention, then ease of operation and cost-effectiveness improve, but security and reliability may deteriorate
Solution Approach 1:
A cloud-based service acts as an intermediary between the user's computing device and the vehicle's onboard computer. The service receives programming instructions from the user, validates them securely, and transmits authorized commands to reprogram the fob interface. This mediator ensures secure authentication and controlled access while enabling user-friendly programming without dealer intervention.
2Ease of operation
If cloud-based programming service is implemented, then ease of operation improves, but device complexity increases
Solution Approach 1:
The complex programming logic, authentication mechanisms, and communication protocols are extracted from the user's computing device and relocated to a cloud-based service. The user's device only needs to provide simple input through a graphical interface, while the heavy lifting of secure communication and fob reprogramming is handled by the external cloud service, reducing local complexity.
3Reliability
If traditional dealer programming process is used, then security is maintained, but loss of time and cost increase
Solution Approach 1:
The system enables users to perform fob programming themselves through a simplified cloud-based interface, eliminating the need to visit dealerships or hire locksmiths. Users can complete the programming process remotely at their convenience, significantly reducing time loss and costs while the cloud service maintains security through authenticated access and controlled command transmission.

AI summary
A system and method for programming a new key fob. Some embodiments include a programmable remote transmitter, designed, and programmed to perform single or multiple operations, optionally incorporated into a custom-made base that attaches to a smart phone case or other mobile devices. The remote transmitter is designed and activated via secured programming provided by an application on the user's mobile device, without the intervention of car dealers, locksmiths or using difficult manual processes. The remote transmitter can be attached to smart phones, mobile devices, or other suitable surfaces (e.g., a briefcase or a vehicle's dashboard) for safekeeping and accessibility.
