Keyless Entry System Using a Smartphone for Vehicle: A Development of Vehicle Security Performance

This study involves developing a keyless entry system using a smartphone for vehicles. The system comprises a mobile application and apparatus with main and secondary modules. The main module comprises a mini-computer, Bluetooth Low Energy module, NFC module, ultrasonic sensor, and control circuit installed inside the vehicle. Connected to it is the Secondary module comprising a Car Battery voltage reader circuit, EFI and Fuel Pump control circuit, and a microcontroller located inside the vehicle hood. The mobile application connects to the apparatus wirelessly and acts as a key. A chip-enabled card is a backup key in case the Smartphone is unavailable. It can activate the application by tapping the chip-enabled card through the Smartphone's NFC. The participants of the study are the vehicle owners and are determined through purposive sampling, which is important in examining the subject characteristics involved in the study. Experts evaluated the system using the ISO/IEC 25010:2011 Systems and Software Quality Requirements and Evaluation Questionnaire. The level of acceptability of the Keyless Entry System using Smartphones in terms of functional suitability, performance efficiency, compatibility, usability, reliability, security, maintainability, and portability was "Excellent". Upon Overall, the system performed its intended function and extended a vehicle's safety features.
