It could be from excessive moisture or wear from continuous usage.

How Does a Car Door Lock Switch Work?

How to Tell a Faulty Car Door Lock Switch

Most modern cars have power door locks and a keyless remote system. The lock switch functions as the actuator’s remote. If the switch has an issue, it’s not possible to activate the actuator, and therefore, there’s no way to operate the locks. Some of the signs include:  Door Lock Functioning Periodically The first indicator that the car door lock switch is malfunctioning is the locks failing to work sometimes. This is often a result of the lack of communication between the door lock actuator and the switch. If the electrical components wear out or get damaged, the door switch functions randomly, causing the door to lock and unlock unexpectedly. If the switch fails to activate the locks and door security system, this is a sign that the door lock switch is not transmitting the appropriate amount of power.  Damaged Door Lock Button or Rocker Most car door lock switches are plastic, making them prone to breaking, corroding, and wear caused by frequent usage or exposure to high temperatures in hot seasons.  Excessive Energy When Unlocking the Door Applying excessive pressure when unlocking the door is also a sign that the switch has an issue, and you need to repair car doors.  Repeated Attempts to Lock or Unlock the Door If you need to keep trying to lock or unlock the door multiple times, it’s a sign that there may be excessive moisture in the car door lock switch.
