Car alarms are sensitive and distributed throughout your car. When you are sleeping inside, you can accidentally activate the alarm by shaking the car or pushing against the window, which is common during sleeping. So how can you sleep in your car without setting off your alarm?

Here’s how to sleep in a car without the alarm going off:

  1. Use the mechanical lock.
  2. Disable the car alarm.
  3. Use alternative security features.

Since you are worried about setting off the alarm while trying to sleep inside your car, this article will show how you can easily solve your problem. Let’s get started!

1. Use the Mechanical Lock 

Car owners have often either locked themselves inside while attempting to figure out a way around the alarm system or unintentionally activated the alarm. The easiest way to ensure your car alarm does not go off is by using the mechanical lock button. 

We are so used to using the fob key that we forget about the physical lock-unlock button inside. This lock is handy when you want to keep your car safe without waking the entire neighborhood. Using the lock button on the drivers’ side will lock the car without setting off the alarm. 

However, make sure the fob has enough charge to operate.

2. Disable the Car Alarm

Disabling the car alarm is a great way to ensure you are not inviting people’s wrath around you. There are multiple ways to do this, including removing the alarm’s fuse or disconnecting the battery. 

Let’s look at these ways in greater detail.

With the Fob Key

Check the batteries on your fob key. There are instances where the alarm refuses to turn off despite using the fob because the batteries are dead. If everything is fine, then press the lock and unlock button on your fob simultaneously. That should do it.

With Only the Key

You can also stop the alarm by using only your key to unlock the car manually. If you have installed your alarm separately, then this might not always do the trick. 

Additionally, switch on the car battery without starting the car and press the alarm key (look at the car manual to locate the alarm button) for about 3 seconds. If the alarm still doesn’t stop, then turn on the ignition. 

Some alarm systems will not even let you start your car. In such cases, either follow the instructions of the alarm manual or contact the alarm manufacturer. 

But in most cases, the above two tricks should work.

Remove the Alarm’s Fuse

You can also locate the alarm wiring and deactivate it by removing the fuse that powers the alarm. This fix is more permanent, and you should do it only if you are confident about what you are doing.

If you have no idea how to remove the alarm’s fuse, you should check out method 2 in this WikiHow article. To summarize, you need to do the following.

  1. Locate the alarm fuse. You will find the alarm fuse in the fuse box of your car. Use the manual if you are unsure.
  2. Identify the alarm fuse. Again, use the manual if you are not sure what the alarm fuse looks like. Aftermarket alarms might operate differently.
  3. Remove the alarm fuse with a pair of tweezers. If you don’t know which one is the correct fuse, keep removing all the fuses one by one until the correct one stops the alarm.

Disconnect the Battery

The last method of disabling the car alarm is by disconnecting the battery. You should only do this if all the other methods have failed. Wear rubber gloves before touching any part of the car’s engine. 

Locate the battery under the hood of your vehicle. It is usually apparent, but some cars keep their batteries in the trunk. Refer to your car’s manual if you can’t find it. Remove the black wire connected to the (-) symbol on the battery. It will immediately cut off power to your car, including your alarm. 

Re-connect the wire.

If you have installed the alarm system later or used a separate alarm system in your car, it might be powered by a dedicated battery. You need to locate that and disconnect it.

3. Use Alternative Security Features

Car alarms are not the only thing that can keep your car safe. If you don’t like car alarms anymore, you should try one or more of the following alternatives. 

GPS Tracking Device

Even though GPS tracking devices lack the same function as car alarms, they are highly effective in tracking stolen vehicles.

Final Thoughts
