Stop the Beeping: How to Turn off a Car Alarm

By Kimberlea Buczeke, November 14, 2017

Car alarms are incredibly important to any driver; whether to locate your vehicle in a crowded parking lot or call for help in times of danger, every car needs one and if you ever need to use it, you'll be glad it's there.

Nevertheless, it is possible — and even common — for car alarms to inadvertently go off, and that can be an inconvenient and uncomfortable situation. If and when this happens and you need to stop the alarm, or when you deliberately use it but it has served its purpose, it's helpful to know how to turn off the alarm quickly. This will stop the loud noises and ensure others that no one is in danger and needs help. Here are some ways to turn off a car alarm that are quick, easy, and sure to work:

Try Starting Your Car

If you're near your car when it goes off — or if remote starting is one of your features — all you have to do is turn the car on to turn the alarm off. Many factory and aftermarket alarm systems are designed to reset when the vehicle's key is used to start the car. 

This method will work in both older cars with more traditional keys and newer cars that have abandoned the system in favor of a button to start the vehicle. Simply turn the key or press the button, the alarm will stop, and you can be on your way!

Hit the Panic Button (Again)

This is one of the easiest ways to shut off your car alarm. As long as you are within the range of your car remote (and if you turned the alarm on, you probably are), all you have to do is hit the button, which is often red and labeled with a horn, a second time and silence should return.

Lock or Unlock the Car

This can be done even if you're not right by your car when it happens. If you're in a parking lot or inside, for example, you probably won't be able to start the car. Hit either the lock button or the unlock button on your remote, and that should do the trick.

Use Your Key To Physically Open Your Driver's Side Door

Another way to disable your vehicle's alarm system is by using your key to unlock your driver's side door. For an unlocked door, lock it with the key, then unlock it again.

Open the Trunk (or Use Other Buttons on the Remote)

There are usually other buttons in addition to those for locking and unlocking on car remotes. One of the most common buttons featured opens the trunk or hatchback, a button which has uses beyond making it easier to put bags inside after a shopping trip. Pressing this button — or holding it, if that's what your car normally requires — will stop an in-progress car alarm. Additional buttons, if you have them, can come to your rescue, too. 

Remove The Alarm Fuse

Most of the time the fuse for your vehicle's alarm system will be located under the hood of your vehicle. The fuse box in the engine compartment will be a small black box. Once you have located the fuse box, remove the top. Sometimes there will be a fuse diagram on the inside of the lid that will tell you fuse locations, sizes and what component it goes to. If the lid does not have a diagram, look in your vehicle's owner's manual.

The alarm fuse may also be located in the interior fuse box, which will be on the inside of your car, commonly on the driver's side, under the dash. 

Once you have located the alarm fuse, remove it and then reinstall the fuse.

Disconnect The Vehicle's Battery

Disconnecting the battery will make all of the electrical systems in your vehicle reset themselves. The alarm system will undergo a hard reboot and reset alarm protocol. 

To disconnect the battery remove the negative battery cable. The negative cable should be black and the positive cable should be red. Leave the negative cable disconnected for around thirty seconds, then reconnect the cable.

Most cars nowadays, including new ones, are equipped with remotes that can lock, unlock, and perform other functions on the vehicle from afar — including starting and stopping the car alarm. In order to stop the alarm once it's sounding, it is most convenient to use a remote. Even though it will most likely take you longer, it's not impossible to complete the task with just a key. Starting the car will always work; this is a foolproof method.

Overall, the alarm is a very valuable part of your car. Make sure you know how to use it, and you'll be driving more safely and comfortably every day.
