Instructions

  1. 1

    Use your remote to turn off the alarm. Regardless if you're planning to permanently disconnect your battery or not, hit the "Panic" button the remote. This may shut off the alarm and allow you to work in peace and quiet.

  2. 2

    Locate the fuse box by referencing your owner's manual. The fuse box is often located below the steering wheel on the left side of the dash or on the right side of the engine under the hood.

  3. 3

    Follow the fuse lid diagram to determine which fuse belongs to your car alarm. Take a pair of needle nose pliers or a fuse puller tool and clamp it around the fuse. Gently pull vertically and the fuse should pop out.

  4. 4

    Disconnect the battery if you can't locate the fuse box or determine which fuse is for the car alarm. With a Phillips head screwdriver, remove the terminal screw on the negative (black) terminal. Once this screw is loosened, you can disengage the terminal, thus shutting off power to the car.

  5. 5

    Disconnect the battery and reconnect it. The alarm may automatically trigger. If this occurs, use your remote to shut it off or check your owner's manual to determine if there is a toggle button that shuts the alarm off.
