On the afternoon of April 17, the Radio Frequency Department (Ministry of Science and Technology) said that the incident of a series of unactivated car and motorbike smartkeys in Me Tri Thuong has been handled.
Previously, on the evening of April 16, the Radio Frequency Department received feedback from readers sent via Facebook FanPage about the phenomenon that many smart lock devices of cars and motorbikes cannot be used in area No. 1 Me Tri Thuong street, Tu Liem (Hanoi).
According to reports, a series of vehicles in this area are experiencing the situation of not being able to unlock with smartkeys, causing inconvenience to people and raising concerns about technical problems or safety risks.
Immediately after receiving the information, the Radio Frequency Department quickly deployed verification, data collection and coordinated handling. By 9:40 AM on April 17, 2026, the Radio Frequency Center Region I (under the Radio Frequency Department) had successfully overcome and handled it.
The inspection results showed that the cause originated from a coffee shop in the Me Tri Thuong area. This establishment uses a wireless call button system attached to tables for customers to press to call staff.
However, due to a technical error, this system emitted a signal at a frequency of 433.91 MHz, which coincided with the operating frequency range of many smartkey devices on cars and motorbikes. This overlap led to signal interference, making smart lock devices unable to recognize control signals.
After identifying the source of interference, functional agencies requested to stop the equipment operation and thoroughly handle the incident, ensuring no recurrence of similar situations.
