What Causes a Car Remote Key to Suddenly Stop Working?

[VonMiguel]

There are several reasons why a car remote key may suddenly stop functioning, including remote control failure and human interference. Remote Control Failure: This occurs when high-power radio signals of the same frequency in the vicinity prevent the car's signal-receiving device from detecting the radio-encoded commands sent by the remote key. As a result, the remote control fails, leading to issues such as the inability to lock or unlock the car doors. Intentional Human Interference: This primarily involves criminals deliberately using car remote jammers. So-called 'car lock jammers' are signal blockers that emit electromagnetic waves to disrupt the car remote's signals, placing the car in a 'false lock' state. This allows thieves to seize the opportunity to commit theft, resulting in financial losses for the car owner.
