How do car alarms go off?

What makes car alarms go off? I'm asking because my car alarm keeps going off at night when I let my dog out. I'm sure it annoys my neighbors, and it definitely annoys me. How do I keep my car alarm from going off at random hours?

Most car alarm systems are triggered by shock or vibration sensors. These sensors will detect when something is moving the car, like a potential thief or your unsuspecting dog. The movement is what triggers the alarm.
To prevent your car alarm from going off in the night, you have two options:
  • Keep your dog away from your car
  • Get your sensor adjusted to reduce the sensitivity
After you’ve adjusted your car alarm, it might be a good idea to adjust your insurance, too. While a high insurance bill might not annoy your neighbors, it can definitely be enough to keep you up at night. Fortunately, the Jerry app can help. Jerry will collect car insurance quotes for you for free, so you can find the lowest prices for the insurance coverage you need.
