Untact vehicle sharing
service through 'Special One'

without a car key

스페셜원 로고.png

Since 2016, we have been researching and developing 'Key+',

a system that allows you to control and drive cars without a car key.

Special One is a manufacturer of convenient cars that begun with a small idea of "how to open a car without a car key," and is developing and producing the world's first digital key 'Key+' that can be immediately used after purchase.

With our vision to provide all non-face-to-face platforms for vehicle-related services and our mission to initiate non-face-to-face connected Key+ with vehicle-connected services, we are striving on developing research to enable non-face-to-face vehicle sharing systems and shared community platforms through Key+.


Through Digital key KEY+

Non-face-to-face vehicle
sharing service

We currently provide smartphone-based digital key
services, which is a key technology in the era of car sharing.

Ultimately, the goal of SPECIALONE is to provide a
non-face-to-face vehicle service platform that allows
people to wash their car and repair their car from

their seat by using the digital key 'Key+'.
