What could be the issue if the car key buttons are not responding?

It could be due to a dead battery. Other possible reasons include nearby radio frequency interference, interference from theft devices, or decoding. Relevant explanations are as follows: 1. Mechanism of action: The remote key operates through a wireless communication system consisting of a transmitter and receiver, which is a low-power radio device. The car's control system identifies the signal code via the Electronic Control Unit (ECU). 2. Signal interference: When the radio frequency band used by the car remote key (314-316MHz, 430-432MHz, 433-434.79MHz) coincides with the frequency band occupied by some devices in the parking location, it is prone to interference, leading to the remote key's "failure."
