Hyundai Mobis Develops Remote Unlock/Start Technology for the First Time in Korea

SEOUL, South Korea–(BUSINESS WIRE)–A smartphone-based smartkey that prevents the risk of smartkey hacking
and provides more user convenience was developed for the first time in
Korean technologies. Competition over automobile and ICT convergence
technologies for the future auto market is now getting fiercer.

(KRX:012330) announced on August 10th that it has recently
developed an integrated smartkey system where a user installs an app on
an NFC-supported smartphone and utilizes it as their smartkey for their

Until now, Hyundai Mobis is the only Korean automotive supplier which
has completed development of a smartkey utilizing NFC technology. The
number of suppliers possessing this technology is rare even in the
global market and this technology has hardly been even applied to
mass-production as of yet. Hyundai Mobis aims to mass-produce the
product from 2019.

Near Field Communication (NFC) is a short-range wireless connectivity
standard that enables data exchange between devices within the range of
10 cm. While NFC has been applied to more areas in IT over the past 10
years, primarily for electronic payments, including transportation
cards, credit cards and membership cards, it has not been developed much
for the automotive industry.

The advantages of NFC-based smartkeys include portability and advanced
security. First, drivers don’t need to carry a conventional smartkey
anymore. They can unlock their vehicle simply by positioning their
NFC-supported smartphone (with an app for security authentication)
closer to the door of the vehicle and can also start it up by pressing
the start button after setting their smartphone on the wireless charging
pad inside their automobile.

The vehicle door knob and the wireless charging pad contain an antenna
that receives NFC signals, which enables communication between the
vehicle and the smartphone. You can install the antenna anywhere inside
your vehicle but can also designate the position according to user

The most important factor when controlling the vehicle via a smartphone
is security. Hyundai Mobis developed an authentication controller
utilizing the latest data encryption and authentication technology,
which enables encryption of data on the vehicle and smartphone and
accurate identification. This provides reliable countermeasures for
smartphone hacking, smartphone loss and data forgery.

Another feature of this new system is that the vehicle owner can
authorize a third party such as their spouse to use an NFC-based
smartkey. This feature is useful when you share a vehicle with others or
need to allow others to use your own.

The third party can use this smartkey system by installing the app under
the vehicle owner’s permission and completing the authentication
process. While the third party uses the vehicle, the owner can control
user permissions for the smartkey to prevent any incidents. For example,
you can allow the driver to use your vehicle only on certain days or
time slots or set the smartkey to unlock the door without being able to
start your vehicle.

“Recently, convergence between automobiles and ICT has been evolving
rapidly and competition among manufacturers is also fierce,” says Cho
Seo-koo, head of Hyundai Mobis ADAS Development Center. “We plan to
develop various new technologies designed to improve user convenience
and prevent security incidents, and remain well ahead of our

Meanwhile, Hyundai Mobis developed and began to produce an Integrated
Body Unit (IBU) from March, which is a first among domestic suppliers.
IBU is a unit that combines 4 ECUs for controlling the Body Control
Module (BCM), Tire Pressure Monitoring System (TPMS) and Parking Assist
System (PAS). This system minimizes interferences or errors among
individual devices and improves system control speed. IBU is also
applied to the NFC-based smartphone smartkeys for locking or unlocking
