    This siren is MUCH louder than the tiny 6 tone that comes with the Viper 5901. It makes my ears ring and will definitely get someone's attention if your alarm goes off. Very high quality design and comes with a key in order to turn it on or off. Nice job DEI.

What Our Customers Say

Had this alarm installed in my Camaro z28 and could not be happier, my car has had two other alarms in the past and this is by far the best yet! No complaints, works great!

Daniel - Austin, Texas Viper Color OLED 2-Way Remote Start + Security System

This product does everything you need, the best part is by the LED confirmation, you will know if your car starts. My husband has a remote start the dealership put in, and if you're not close to the vehicle to hear the horn beep, you're out of luck. I got this for my daughter last year and for me, and it works like a charm. You can't go wrong. The distance is great on it!

Cheryl - Cleveland, Ohio Viper 1-Button 2-Way Plus Remote Start System

Best thing I ever put in a car. I live in Wisconsin where winter cold is colder than cold, it is great to walk outside and get into a warm car, windshield is clear of snow and ice, I bought and had it installed by Best Buy, it works great and the installer was very helpful and still is when I call with a quick question.
