- Once you have the physical key, use it to manually unlock the driver’s side door as mentioned above.
Ignition Method (If Applicable):
- Some vehicles have a method for deactivating the alarm by turning the key in the ignition.
- Insert the key into the ignition and turn it to the “on” position without starting the engine. This may silence the alarm. Some vehicles require you to cycle the ignition key from “off” to “on” multiple times to reset the alarm.
Remove the Car Alarm Fuse or Relay:
- Refer to your vehicle’s owner’s manual or fuse box diagram to locate the fuse or relay associated with the car alarm.
