Technician installing a car alarm system in San Leandro.

Protecting your vehicle is more important than ever. Whether you live in the city or commute regularly, a reliable car alarm can be your first line of defense. But with so many options out there, how do you know which car alarm system type is right for your car?

At Audiomotive, we specialize in Car Alarm Installation in San Leandro and surrounding areas like San Lorenzo, Fremont, and San Francisco. In this guide, we break down the most common types of car alarms and help you choose the best fit for your vehicle and lifestyle.

1. Passive Car Alarms

Passive alarms activate automatically when you turn off your ignition and lock your doors. You don’t need to press a button or activate anything manually.

Best for:

  • Drivers who tend to forget to arm their systems
  • Those looking for hassle-free protection

Features:

  • Automatic arming
  • Door, trunk, and hood protection
  • Interior motion detection (in some models)

2. Active Car Alarms

Active systems require manual arming via a key fob or remote control. While not as hands-off as passive systems, they provide strong customization.

Best for:

  • Drivers who want control over when and how their alarm activates
  • Vehicles in high-traffic or high-theft areas

Features:

  • Remote locking/unlocking
  • Panic button
  • Real-time alerts (depending on the model)

3. Two-Way Car Alarms

These alarms allow communication between the alarm and the key fob or smartphone app. You’ll be alerted if something triggers your alarm—even if you’re blocks away.

Best for:

  • Urban commuters
  • People who park far from their home or work

Features:

  • Real-time alerts
  • Remote monitoring
  • Smartphone app integration (in many models)

4. Immobilizer Systems

This advanced security option prevents the vehicle from starting unless the correct key or token is present. It’s often built into factory systems but can also be added aftermarket.

Best for:

  • High-value vehicles
  • Areas with frequent auto theft

Features:

  • Engine disabler
  • Encrypted chip or key recognition
  • Theft deterrent even if entry is gained

5. GPS-Enabled Alarms

Looking for next-level protection? GPS alarms allow you to track your car in real time, which is essential for theft recovery or monitoring teen drivers.

Best for:

  • Fleet owners
  • Parents or frequent travelers

Features:

  • GPS tracking
  • Geofencing alerts
  • Smartphone control
