Why does the car alarm keep going off after remote locking?
2 Answers
It is most likely due to the excessively high sensitivity of the anti-theft alarm. Here are the relevant explanations: Excessive sensitivity: The sensitivity of the anti-theft alarm is set too high, causing the device to trigger an alarm with even slight vibrations. It could also be due to wiring issues with the main unit of the alarm, requiring timely inspection, repair, or replacement. Solutions: You can use the key to unlock the car and then press the lock button to deactivate it, but this only temporarily solves the problem; if the sensitivity of the anti-theft alarm is too high, it can be adjusted at the main unit of the alarm; if neither of these methods works, you need to visit a 4S shop for computer diagnostics to eliminate the fault.
As an experienced car maintenance enthusiast, let me talk about this common issue. The key reasons for frequent alarms after remote locking usually lie in doors not being properly closed or an overly sensitive security system. I often see car owners overlook the trunk or side doors not being fully shut, and the system misinterprets gaps as triggers for alarms. Another common issue is when the remote key's battery is nearly depleted; weak signals can confuse the system into thinking there's an intrusion, thus setting off the alarm. Interior sensors can also be easily activated by items moved by wind, so avoid placing easily movable objects in your car. If this happens repeatedly, first test locking the car with a mechanical key. If the alarm stops, it's a remote issue—replace the battery immediately. If the alarm persists, it might be necessary to check the security control unit. Don't attempt to dismantle it yourself; getting a professional inspection at a specialized shop is the safest way to prevent minor issues from turning into major problems.
