1. Locate the alarm siren, usually installed in the engine bay.
2. Disconnect the siren's power connector.
3. Open the driver's door and locate the fuse box.
4. Remove the alarm fuse.
5. Close the driver's door and start the engine.
6. The alarm should be disabled.
Note: Disabling the alarm will also prevent the car's horn from honking when the alarm is triggered. If you wish to keep the horn functional, you can leave the fuse in place and disconnect only the siren.
