Why Does the Car Key Unlock Alarm Keep Ringing?

[Lynne]

Reasons for the car key unlock alarm continuously ringing: alarm being overly sensitive, faulty door contact switch, excessively high sensitivity of the anti-theft sensor. Alarm being overly sensitive: If the alarm is too sensitive, even slight movements around the car can trigger continuous ringing. In this case, simply adjusting the sensitivity will suffice. Faulty door contact switch: A faulty door contact switch can also cause the alarm to ring. It needs to be repaired at a service point. Excessively high sensitivity of the anti-theft sensor: If the anti-theft sensor's sensitivity is too high, it can be adjusted. There is a sensitivity adjustment knob on the anti-theft vibration sensor, and a slight adjustment should resolve the issue.
