Smartphone-Attached Key Fob Programming Without Dealer Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing keyless remote devices require complex and dealer-intensive programming processes, making it difficult for users to self-program new vehicle fobs without intervention from car dealers or locksmiths, and there is a need for a solution that allows secure and accessible key management.
Innovation Solution
A user-programmable remote transmitter platform, referred to as the Attachable Remote Key (ARK), which allows secure programming without dealers or locksmiths, and can be attached to smartphones or other devices, utilizing a smartphone app and cloud-based services to reprogram vehicle fobs wirelessly, enabling commands like locking, unlocking, and starting vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional dealer-intensive programming processes are used, then security and reliability are maintained, but device complexity and difficulty of operation increase significantly
Solution Approach 1:
The patent introduces a smartphone application as an intermediary between the user and the vehicle's onboard computer. The app communicates with the vehicle through wireless interfaces (Bluetooth, Wi-Fi) and mediates the programming process, translating user-friendly actions into the complex protocols required by the vehicle system. This intermediary layer maintains security through authenticated communication while presenting a simple interface to users.
Solution Approach 2:
The system enables users to program their own keyless remotes without requiring dealer or locksmith intervention. The onboard computer automatically processes the programming requests from the smartphone app, and the system self-manages the authentication and data transmission processes. Users can independently add, delete, and manage key fobs through the app interface.
2Manufacturing precision
If dealer intervention is required for programming, then programming precision and security are ensured, but loss of time and accessibility are increased
Solution Approach 1:
The patent replaces the mechanical process of physical dealer intervention with a wireless electronic system. The smartphone app communicates with the vehicle's onboard computer through wireless interfaces (Bluetooth, Wi-Fi), eliminating the need for physical presence at a dealer location. The programming data is transmitted electronically, maintaining accuracy while dramatically reducing the time and logistical requirements.
3Reliability
If key management is centralized at dealers, then security is maintained, but adaptability and user control are reduced
Solution Approach 1:
The system transitions from a static, dealer-controlled key management model to a dynamic, user-controlled system. The smartphone app provides real-time control over key fob programming, deletion, and management. Users can dynamically add or remove key fobs as needed, and the system adapts to user requirements while maintaining security through authenticated communication protocols and encrypted data 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.
