Tesla Alarm Keeps Going Off [10 Proven Fixes]

You are here because you had the traumatic experience that Tesla Alarm Keeps Going Off. They were right when they said the Alarm is a powerful theft deterrent.

 Because it detects every minor tilt or motion, but at the same time, it keeps going off unnecessarily.

What gives? How do we tackle the problem? You will find all the answers here.

Why Tesla Alarm Keeps Going Off

Tesla Alarm Keeps Going Off

Here are all the possible reasons why your Tesla Alarm keeps going off with the fixes. I have spent 12 hours researching and coming up with these solutions.

1. Sentry Mode Settings 

As a new Tesla user, you are unaware of the alarm settings. That would only alert you when there is an actual threat.

Both your Tesla mobile app and the settings on the Tesla touchscreen need a few changes when you install the app on the phone.

If you set the Location settings on the Tesla mobile app only to detect while using the app, the Alarm will keep going off randomly. You have to make a few changes to avoid activating Sentry mode at random moments.

The Sentry mode is designed to record any interruption when you are away from the car. The distance must be greater than 30 feet. You will immediately receive the notification that ‘Sentry Mode Triggered Alarm.’


You can make these changes in the Tesla touch screen so that the Alarm does not go off due to a triggered Sentry Mode.

  • Open ‘Settings’ on your iPhone or Android device.
  • In Android, scroll down to the ‘Apps Management’ in the settings menu. Then tap on the ‘App List.’ 
  • From here, you will select ‘Tesla.’ 
  • The next page will have a ‘Permission’ bar.
  • There are several options that you can select according to your preference. Therefore, if you have chosen the ‘Location’ only when using the app, change it to ‘Always’
  • For iPhone, you must open the settings and scroll down to ‘Tesla.’
  • In the App settings, select the Location’ tab and set it to ‘Always.

2. Hyper Sensitive Sentry Mode

Tesla puts cutting-edge technology in all its vehicles. The same goes for Tesla’s security system, which is too sensitive. Even when a fly or a car with loud music passes, the Alarm triggers.

I experienced one time when I left passengers in a Tesla, and the Alarm went off. That experience is worse for someone in the car because the alarm sound is set to be too loud. 

If a passenger can’t access the Tesla app, they can’t turn the Alarm off by any means. Not to mention that in that situation, the door locks automatically. 


  • To avoid such situations, you can apply a few changes in the Tesla touch screen and mobile phone app.
  • You must enter the List in the Tesla Touch screen and hit the ‘Controls.’
  • Afterward, navigate to ‘Safety.’
  • Here, you will have to scroll down to the ‘Alarm.’
  • Now, you need to adjust the alarm sensitivity as you prefer.
  • Therefore, tap on to ‘Alarm Sensitivity’ and decrease it.

3. A Painful Experience For Babies and Pets

You must never leave any passenger in the car when they don’t have control over the alarm system. For example, pets and babies cannot handle the situation when the Alarm suddenly goes off. 

Fortunately, Tesla has a unique ‘Dog Mode’ you can turn on when leaving the car.

It has dual benefits: it keeps the internal environment at optimum temperature. Secondly, when a passenger touches the handle accidentally, the Alarm will not go off.

Fix:Set The ‘Dog’ Mode

  • To set the dog mode, you must set your Tesla in the ‘Park.’
  • Next up in the controls, access the ‘Climate Control.’ 
  • On the right-hand side, you will see a ‘Dog Mode.’ option, which would maintain the perfect temperature inside, and the Alarm would not go off when the pet or kids touch the doors.

4. Bug In The System

The Tesla’s computer system may get messed up and respond differently than the set instructions. Similarly, the system bug would set off the Alarm at random times.

To correct it, you need to report the bug to the Tesla. 


  • You have to hold the scroll button on the right side of the Tesla’s Steering wheel.
  • The touchscreen will display that Voice command mode is activated.
  • Put in the command that you are reporting a bug.
  • The system will automatically submit this report to Tesla. Therefore, they would monitor your car’s software and will remove any glitch that causes your Alarm to go off. 

Quick Tips

  1. Suppose you cannot solve the Tesla’s Alarm triggering at any time. Then, you can turn off the Alarm for some time by going into the ‘Controls’ and scrolling down to ‘Safety.’ Then Select the ‘Security Alarm’ and tap on the ‘Turn Off The Car Alarm.’
  2. Excluding the home from the Sentry Mode will save your battery, and you will not hear repeated alarm noise. To do this, you have to hit the ‘Controls’ and scroll down to the ‘Safety.’ now uncheck the ‘Home’ from the List where Sentry mode will actively record video and turn on the Alarm.

5. Faulty Door Handle Sensor

The Tesla’s door handles have sensors. When someone tries to break into the car, the sensors immediately send a message to the Alarm, and it goes off. 

But with time, the sensor’s efficiency reduces, and it begins sending false alarms. It’s a simple technology failure. 


  • It would be best to clean the Tesla’s door sensors from dust and grime. Therefore, contact Tesla’s expert technician and book an appointment. 

On the other hand, you can calibrate the Tesla’s doors and windows by following these steps.

  • In the ‘Controls,’ enter the ‘Service and Security.’ Make sure that you have a car in the ‘Park.
  • Then tap on the ‘Calibrate Windows and Doors and follow the instructions.
  • The recalibration of the doors will reset the system and remove any glitches. So the Alarm would not trigger randomly.

6. Faulty Hood Latch Sensor

The Hood latch also has a sensor connected to the Alarm. If Any dust or grime gets stuck on your Tesla‚Äôs Hood latch, it will reduce its efficiency. 

The sensor will send false signals to the Alarm due to incorrection detection, and you will receive a notification on the phone that the Alarm is going off. At the same time, the whole neighborhood can get disturbed.


It would help if you cleaned the sensor. But it is located under the hood; therefore, seek the help of an expert Tesla technician to detect any fault in the sensor. 

They will check the wires and sensors for malfunction and clean the sensors to avoid any problems in the future.

7. Malfunctioning Key Fob

Usually, Tesla uses the Key Card to unlock the car. But with some models, you get the key fob. The faulty key fob may convey false alarms to the Tesla, and the Alarm would go off even when no one is around. 


  • You have to change the batteries on a malfunctioning key fob to prevent the situation. 
  • You need to use a flathead screwdriver to open the plastic cover enclosing the key fob’s battery.
  • Now remove the old battery and insert the new one in place. 
  • Put the cover back on.

8. Update The Software

Tesla keeps releasing new updates for its software. Any old software may no longer support the settings, and you may need to install the latest update. It can solve the issue in the systems, and the Alarm would not go off repeatedly.

  • You must ensure your Tesla is at a safe location and in the ‘Park.’
  • Then, connect the Tesla with high-speed Wi-Fi to install the updated software version.
  • Enter the Controls and hit the ‘software’ at the end of the menu.
  • You will set the ‘Software Update Preference’ to ‘Advance’ and initiate the installation.
  • Wait until the installation is completed.

9. Low battery

It’s a common reason that your Tesla alarm goes off. When the Alarm gives a false alert at a time, you will notice the battery is drained the next day. That’s a sign that you have to test the battery.


You can test the battery’s health using a multimeter. Alternatively, charge the battery, and if it works fine afterward, something else triggers the Alarm.

10. Corrupt Alarm Control Module

When everything works fine in the above List, you might want to check the Alarm’s control module. The faulty alarm control module will send the wrong signals, and the Alarm goes off. 

It’s a tricky business; therefore, you must book an appointment with Tesla’s local dealership to trace the fault.

Take the Tesla and your wallet because it can cost a hefty price.

How To Reset Tesla To Troubleshoot Faulty Alarm System

Here is how you can reset the Tesla. It will reset the electricals to their factory settings and may remove the bug in the faulty alarm system.

Soft Reset A Tesla

  • You must place the car in ‘Park’ and simultaneously press both scroll wheels on the steering wheels.
  • Hold it until the touchscreen turns off.
  • They leave the scroll wheels and wait until the screen turns back on.
  • Please do not interfere with the screen’s functions when it turns back on for an additional 1 minute.

  • Ensure that ‘Dog mode’ and ‘Climate controls’ are also turned off.
  • Afterward, open the hood and access the battery.
  • Use safety gloves and appropriate wrenches to disconnect the battery terminals.
