Why choose an aftermarket car alarm?

The standard alarm that comes with a car is surface-level protection, as thieves can bypass them and break into a car without setting it off. An aftermarket alarm has an indicator light that flashes to let people know a security system is installed. No alarm is perfect but an upgraded system will be much more effective than a factory alarm.

How to install a car alarm

Before choosing which alarm to buy and install on your vehicle, make sure you are aware that some need to be installed by a certified technician. If you have a system you can install it yourself, thoroughly read the instructions and have the right tools available. Here is a YouTube tutorial from Mighty Car Mods on how to install a car alarm.

1-way vs 2-way alarm system

A 1-way alarm system only allows you to send a signal to the car, while a 2-way system lets you send a signal to the car while receiving one back. 1-way alarms can lock, unlock and start the vehicle while 2-way systems receive real-time notifications and let you know if the vehicle has been started or if the alarm has been triggered.
