Why My Security Light On in My Car

When you arrive at your car in the morning, the first thing you usually do is turn off your headlights and taillights, lock your doors, and ensure all of your windows are closed. But what about your security light? According to the National Institute of Standards and Technology (NIST), most cars today come with one or more security lights that should be turned on when you’re driving in low-light conditions. Here’s why:

What could be causing my car’s security light to come on?

There are a few potential reasons why your car’s security light might be on. Some of the more common ones include:
-A broken window that needs to be fixed -This is a common issue, and it can cause the alarm system to go off. If you’re able to fix the window yourself, make sure to do it quickly before the alarm triggers again.
-A stolen car -If your car has been stolen, the thief probably disabled the security system in order to avoid being caught. If you notice that your security light is coming on more often these days, it might be a good idea to get a new security system or install one yourself.

How can I reset the security light in my car?

If you have a car with a security system, the light will turn on when it’s time to reset the system. All you need to do is open the car’s door and hit the button on the inside that resets the system.

What if the problem is not with the security light, but something else in my car?

If you’re like most people, when your security light starts blinking in your car, the first thing that comes to mind is that something is wrong with your car’s security system. However, there are other possible explanations for why your security light is on, and it’s important to troubleshoot them before assuming the worst.

Here are six common causes of security light problems and how to fix them:

1) The light is faulty. If you have a newer car with a computerized security system, the light may be faulty and need to be replaced. If the light has been working fine for months or years but now starts blinking, it may be due to a software issue that needs to be fixed. Check the owner’s manual for instructions on how to test and/or replace the light.

2) The key fob is not working. Make sure you have charged the key fob and inserted it into the ignition. If you still can’t get the security light to turn off, try resetting the car by pressing and holding down both of the button on the key fob for five seconds while turning the key to “on.”


If you’re experiencing trouble understanding why your car’s security light is on, keep reading. Many times, when a security light is on in a vehicle it means there is an issue with the car’s keyless entry system. This can be caused by a broken remote or by something as simple as dirt or dust getting stuck in the sensor. In most cases, simply cleaning the sensor will solve the problem and turn off the security light. If this doesn’t work, there may be more serious issues involved that require professional attention.
