Shut Off A Car Alarm That Won’T Quit

It’s annoying when a neighbor’s car alarm won’t quit and embarrassing when your own is the culprit. Knowing how your particular alarm works will save you (and others) from ringing ears. Read through the owner’s manual before you have a problem. When the alarm is blaring, your wits may desert you.


1. Check for user error. Consult the owner’s manual for directions on turn the car alarm on and off.

2. Put the key in the ignition and try to start the car. On many systems this will shut off the alarm.

3. Find the alarm’s fuse. It may be in the fuse box, usually located below the steering wheel to the left. Many cars also have other fuse boxes (sometimes three or even more) inside the engine compartment. If it’s an aftermarket alarm (installed after the car left the factory), you’ll find the fuse under the hood, usually on a wire connected to the positive battery terminal.

4. Locate the fuse that has the alarm label. You should find a fuse diagram on the lid of the fuse box. An aftermarket alarm won’t have any label. Don’t worry; removing the wrong fuse won’t cause any damage. If you pull out a fuse and the alarm stays on, put that fuse back in and try another.

5. Pull the alarm fuse with the fuse puller (sometimes found in the fuse box) or a pair of needle-nose pliers. Sometimes you can remove a fuse using your fingers.

6. As a last resort, disconnecting the battery’s negative terminal will stop the alarm, but it will also keep your car from starting.
