The safety and security of a car is the priority of the manufacturer and the owner. The technologists have sought ways to ensure the vehicle is safe from thieves and other unauthorized activity. The warning alarms and other systems ensure the car is safe from such issues.
What Does a BMW Car Alarm Sound Like? BMW cars have anti-theft alarms, and they make chirp beep or siren-like sounds. It is present beneath the front seat or on the driver’s side dashboard. You can turn it off by pressing the button on the keys.
There is no doubt that alarms protect automobiles, but they can be annoying. You can disable them on the orders of Government authorities in such cases. But it can put the vehicle in danger of being stolen.
What kind of alarm do BMW cars have?
BMW cars are well renowned for their advanced technology and sky-scorching prices. These vehicles are more expensive than ordinary cars and are susceptible to getting stolen by thieves. Therefore, the manufacturers have installed high-quality anti-theft alarms in their systems.
These are essential to protect the car in a parking lot or other less populated areas. They keep the owner alert of any unusual activity outside or inside the vehicles. The features of these alarms differ in different BMW models.
They have flash warning lights and acoustic warnings to warn the owner about the danger around the car. Motion and tilt sensors are also part of these alarming systems. This system contains sensors that guard the door, windows, trunk, or other entryways of the BMW to prevent unauthorized access.
These anti-theft alarms give warning sounds and lights in the following situations.
- When someone tries to open the door, trunk, or lid
- Movement in the interior space of the car
- changes in the tilt of the vehicle in case someone is stealing the wheels
- Towing or lifting attempt on car
- Disconnected battery voltage
What type of sound does the BMW car alarm make?
The anti-theft system uses both types of warning to alert the people in the surroundings to guard the safety of BMW. The acoustic alarms have different sounds in different vehicle models. Mainly, it combines high and low-pitch notes to make a new pitch sound.
Manufacturers use this strategy to keep the sound unique. In this way, they give different pitched notes to each alarm in all models of the BMW car. The high pitch is also used to keep the owner and surroundings aware of the vehicle. A soft and melodious sound is not feasible for such purposes.
Mostly, it sounds like a chirp-chirp-chirp in some vehicle models. It just sounds like the warble of a bird. But this chirp chirp sound has high-pitched notes and feels unpleasant to the ears. In some models, the alarm sounds like a siren and a horn.
This horn or siren looks more like the sound coming from the police vehicles. Some of them also have a beep-beep sound that has one high-pitched note in it.
I once heard a unique beep beep sound while parking the car in the garage. Later, I came to know that the sound was coming from the BMW car of my old friend. It is easy to adjust the alarm sound volume in some BMW models. But none of these sounds are pleasant to the ears and can create inconvenience in the surrounding area.
Where is the alarm located in the BMW Car?
The location of the anti-theft alarm can vary. But in most cases, it is installed on the driver’s side dashboard and beneath the front seats.
It can also be present beneath the plastic trim covering the door. Some alarm systems are installed near the engine bay, and the tilt or motion sensor is attached to the rearview mirror.
The additional wires are also connected to other parts, like the front anterior of the vehicle. In this way, it can sense slight changes in the position or movement inside the car.
How to switch On and Off the alarm in a BMW car?
The alarm in these vehicles gets on and off every time you lock or unlock the doors with the keys or other accesses. It turns on when you open the doors or windows with the keys. But you can open the trunk lid with the alarm switched on.
Use the vehicle’s key to activate the panic mode in the alarm system. Press the button on the key for about three seconds. Then press the button for 2 to 3 seconds for 3 times in succession.
When the system is turned on, the flashlight on the interior mirror flashes after two seconds. The indicator light turns n for about ten seconds and then for every 2 seconds.
The tilt and motion sensors do not activate if the doors and windows are not closed properly. Once the doors and windows are closed, these sensors get activated.
Some situations can trigger the tilt and motion sensor even if no one attempts to steal the car.
- During car washing
- The presence of animals in the car
- During the transportation of the BMW
These sensors can be turned off in this condition. Press the button present on the key within 10 seconds of locking the doors. The indicator light will flash for approximately 2 seconds and then continue. These sensors will be active after unlocking the doors.
Why is my BMW car alarm going off randomly?
The alarm gets activated even if no one has touched the car. It can ring even if the vehicle is parked in a parking lot. Various reasons cause the anti-theft warning to go off.
Fault in wiring
Any defect in the system’s wiring can cause it to go off. The wires of the sensors can get worn out after some time. They can also lose connection with the sensors, which causes the alarm to go off randomly.
In such a situation, you need to fix the broken or damaged wiring of the system. Reconnect the wires with the sensors to troubleshoot the issues. You can also replace it with a new one.
Dead or weak batteries can also activate the alarm system in the BMW car. The acoustic alerts get triggered if the battery cannot provide enough power to the system. Low voltage from the batteries can also cause it to activate.
Old batteries can not provide enough power to this warning system. You should fix the issue by checking the battery with a voltmeter. Low voltage from the battery shows that it is worn out or old. In such a situation, replace the battery to fix the issue.
Fault in alarm sensor
The tilt and motion sensor can also be faulty in such a situation. They can also cause the alarm to turn on randomly. Any defect in the control module can also raise this problem. The control module sends the wrong signal from the sensor to its system.
In such a situation, you need a complete scan of the alarm system to fix the problem. In many cases, defects in the hood switch can also cause it to go off randomly. You can replace the hood switch to fix this issue.
