Make Sure You Have Everything You Need!

Nearly all cars require an immobilizer bypass to add a remote start system. Click here to add one to your order!

Remote Start Car Alarm

Remote Start

Allows a vehicles engine to active without physical contact from the user. This feature is useful for warming up your vehicles engine and transmission to operational temperatures. In cold climates you can have your interior hot or in warm climates you can cool it down before use. All of this can be done while in the comfort of your home or office.

Keyless Entry

Keyless Entry

Performs lock and unlock tasks without physical contact with the vehicle. Power door locks can be controlled from several feet away or even within a building using a remote fob. The fob emits a radio frequency that is digitally encoded to prevent frequency stealing so no one can enter into your vehicle without your wireless transmitter.

Dual Zone Shock Sensor

Dual Zone Shock Sensor

This shock sensor utilizes warning chirps for minor disturbances and will trip the alarm if it detects more serious impacts or disruptions. Most dual zone shock sensors have adjustable sensitivity to reduce false alarms or warnings. These sensors let would-be thieves know that your vehicle is equipped with an advanced alarm system and to keep away.

best bang for your buck

sonic shipped fast,installation was easy if you understand wiring we used it all winter and never failed to start once. no false alarms, good range on starter maybe to good. hit it in your pocket and the thing starts. i cannot say enough good things about it for the cheap price dont let that fool you it really works great.i've bought several items from sonic and have always been completely satisfied. Ive never had to return anything so i cant comment on that but that should tell you something and oh ya I'm in Canada they kick the heck out of our prices

Great alarm for the price.

For the person who is looking for basic features and remote start, this is a great choice. The only problem I had was the shock sensor didn't work right out of the box. Of course I didn't have time to install the alarm withing the first 30 days of purchase so the Sonic customer care was not a great experience. They did offer to warranty the item, BUT the shipping was as much as the cost of a new shock sensor. Sonic customer care was horrible and made it extremely difficult to return or exchange the item. If you are going to buy ANY product from Sonic Electronix, i recommend testing it out as SOON as you receive the product, as i am finding out the hard way with EVERY purchase.

Python 513

Being a new car owner I was overwhelmed with the range of alarms available. I'd never heard of Python alarms but decided to purchase this one because it was a great price and had the options I wanted (mainly being able to turn the car on from inside). I must say it's a great alarm. It's easy to use, is not super sensitive (living by the river we get a lot of loud thunder and we're on an airplane route) so it doesn't go off at every little thing and its LOUD!!!

Great Product for a Great Price!!

If you're looking for an alarm or remote starter this is a great product to have. I love dei products and this model even though it wasn't a viper does the exact same thing and is very reliable. The remotes are cheap to replace but you wont have to do that for a loooooong time. The install is pretty staight forward not much extra you have to do to make this work. Free AND fast shipping. This was a no brainer. I highly reccomend this alarm!
