Acura Legend alarm activates when attempting to unlock door on Acura Legend

Some Acura Legend owners report experiencing issues with their alarm activating when attempting to unlock the door. This behavior may occur due to a malfunction in the electrical switch within the driver's door lock mechanism, which can prevent the security system from deactivating properly. Additionally, if the red security light on the driver's side door blinks when locking, it indicates that the alarm is armed, and opening the door without disarming it will trigger the alarm. Owners are advised to check for faults or corrosion in the door lock switch and consider unlocking the passenger side door as a potential workaround. Another method some owners find effective is to unlock the driver's door with the key while the alarm is armed and hold it in the unlock position for about five seconds, which may stop the red security light from blinking. In some cases, the alarm has been known to go off if the door is opened before pressing the unlock button on the key fob, possibly due to the key being in range. These insights can assist owners in troubleshooting and resolving alarm activation issues.
