The Crime Guard 533i4 is a wonderful car alarm for anyone intimidated by the thought of installing auto electronics gear. To simplify the installation process, the 533i4 can be ordered with a harness designed specifically for certain types of vehicles.

The 533i4 is a complete system that comes with a Psycho Siren that produces either a steady or variable tone; either tone is incredibly loud. If that isn't enough to deter a thief, the 533i4 has a starter disable, so they can't steal the car even if they get in. In addition, a 60-second countdown delay protects against carjacking. This is a sophisticated system that has a dual-zone shock sensor that differentiates between a light tap and a hard hit. The 533i4 also functions as a keyless entry system with two auxiliary channels.

One of our favorite features is a personal panic alarm that sounds the siren if your personal safety is threatened. The system comes with two extended-range remotes, and a 9-volt backup battery is also included. The Crime Guard 533i4 is a fabulous system with features that make it very usable and easy to install.

The listed price of $149.99 is the retail price from Crutchfield, as Crime Guard does not provide MSRPs and instead allows retailers to set the price.
