Hanoi: Found the 'culprit' that paralyzed the smart key of motorbikes in Kim Ma street area

For nearly a month now, people living and working in the area around houses 253, 255, 269 Kim Ma ( Hanoi ) have encountered a phenomenon where motorbikes using smart keys cannot be started.

To start the engine, people are forced to move their vehicles away from this area.

Receiving feedback from people via fanpage on the afternoon of August 23, the Regional Radio Frequency Center I (Radio Frequency Department - Ministry of Science and Technology ) quickly conducted an inspection.

After conducting the measurement, the authorities determined that the "culprit" causing the interference was a QR code scanning device used to compare Vietlott results. This device was faulty and continuously emitted interference signals directly to the 433.05-434.79 MHz frequency band, which is exempt from licensing for remote control devices such as smart keys (according to Circular 08/2021/TT-BTTTT).

The main cause of the incident is that the radio wave application equipment does not meet quality standards or is caused by technical problems when operating.

As soon as the device was handled, the smart locks of all vehicles in the area returned to normal operation, ending the inconvenience and anxiety of the people.

Authorities and experts recommend that people and organizations should only buy and use radio wave application devices with clear origin and source, ensuring corresponding technical standards (certified conformity, declared conformity, and labeled conformity).

When encountering a phenomenon of suspected interference with smart keys, people can report it via hotline 0862.92.92.92 of the Radio Frequency Department or notify the regional Radio Frequency Centers across the country or the local Departments of Information and Communications./.
