What Causes the Keyless Entry Door Handle Button to Malfunction?

[ThomasRose]

Keyless entry door handle button malfunctions can be attributed to the following reasons: Circuit Board Failure: If the keyless entry door handle button is unresponsive, it may be due to a malfunction in the smart key's circuit board, causing the sensing system to fail to provide feedback. In such cases, if the issue cannot be resolved immediately, you can use the backup function on the smart key to unlock the door and use the vehicle, then visit a 4S store for inspection and repair at a later time. Recognition Interference: Keyless entry utilizes advanced RFID (Radio Frequency Identification) technology and identity code recognition systems, which can sense the owner's proximity to the vehicle without the need for traditional mechanical keys to unlock the door or start the vehicle. As long as the system detects the smart chip key on the user, it will unlock all vehicle permissions, allowing the owner to use the car seamlessly.
