Before Anything Else, Check Your Owner’s Manual
The next solutions are a little more invasive and require you to be comfortable tinkering with your car and its parts. That’s why you should check your owner’s manual before doing anything else.
The manual might indicate that there’s a secret button or another little-known control you can press to turn off the alarm when it doesn’t stop screeching. While not incredibly common, some auto manufacturers include unique controls like this so that owners will head to licensed workshops and pay a fee to get the issue taken care of.
If your owner’s manual doesn’t indicate a way to turn off your alarm beyond what you’ve already tried, continue reading.
Remove The Alarm’s Fuse
You’ll need to locate the fuse responsible for your car alarm’s power. Fuses send electricity to different parts of your car, so removing the alarm’s fuse won’t stop power from the overall battery connected to your engine (remember, car alarms need to run when the engine is off, so they have a distinct fuse).
The exact location of the fuse can differ from model to model. But it’s generally beneath the hood of your car. Check your owner’s manual and look for a picture or a diagram indicating the location of the alarm’s fuse box.
Take a pair of pliers and use them to remove the appropriate fuse. That should take care of the alarm in all cases except one (noted below) since the alarm won’t run without electricity.
Disconnect The Alarm Battery
In the event that you can’t find your alarm’s fuse, you can always disconnect your car battery. But disconnection is only recommended under the most extreme circumstances. You should only do so if you have the experience needed to be safe. Certain car models might not let you disconnect the battery without specialized tools found at licensed dealerships or maintenance shops.
Provided that your battery can be disconnected without special tools:
- open your car’s hood
- remove the negative terminal on your car battery. It will be marked with a minus (-) symbol
- place the connecting terminal where it won’t touch the battery
- re-establish the connection
By replacing the connecting terminal, you’ve essentially reset your car’s battery entirely. The alarm should stop now. If not, you’ll need to take your vehicle into a shop for a more detailed inspection and repair work.
