Why does the car key suddenly lose its sensing function?

[VonElias]

The reasons why the car key suddenly loses its sensing function are as follows: 1. The car battery is dead: This causes the vehicle to fail to receive signals, and the car remote key cannot open the door due to lack of power. 2. Car remote control failure: Due to the presence of high-power radio signals of the same frequency in the surrounding area, the device inside the car that receives frequency signals cannot receive the radio coding instructions sent by the remote key, resulting in the failure of the car remote control, such as being unable to lock or open the door. 3. Intentional human interference: This mainly involves the deliberate use of car remote control jammers by criminals. The so-called 'car lock jammer' is a signal blocker that emits electromagnetic waves to shield the electromagnetic waves of the car remote control, putting the car in a 'false lock' state, thereby creating an opportunity for theft and causing property losses to the car owner.
