What Are the Reasons Why a Car Door Cannot Be Opened?

[DeJocelyn]

Car doors may not open due to reasons such as aging remote transmitters, magnetic field interference, or door jammers. Aging Remote Transmitter: If the car is locked using a remote key, it is likely that the remote lock is malfunctioning or the antenna of the car's remote transmitter has aged, causing the remote key to fail. In this case, a spare mechanical key can be used to lock the door. Magnetic Field Interference: Another scenario is strong magnetic field interference around the car. Since smart keys use low-intensity radio waves, they may not function properly under magnetic interference. Door Jammer: If the car frequently fails to lock remotely in a particular location, the owner should be cautious of door jammers. Some criminals use radio signal blockers that emit electromagnetic waves at the same frequency as the car's locking signal, thereby disrupting the electronic code of the car's central locking system and temporarily disabling it.
