How to Disable the Alarm When Opening the Door with a Mechanical Key?

[DelJulian]

To disable the alarm when opening the door with a mechanical key, you can either turn on the AUTO automatic lights or turn off the lights, or simply turn on the power to stop the alarm. A car alarm is a security device installed in vehicles that sends signals to the controller when someone hits, impacts, or moves the car, indicating the intensity of the vibration. The alarm works on the principle that when the sensor is struck or shaken, a small ball inside the chamber rolls, breaking the circuit formed between a smaller secondary electrical contact and the central electrical contact when it rolls away from the secondary contact.
