Remote Start Car Alarm

Remote Start

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.

General Features

Security System Type
This indicates whether the product is a security car alarm product, remote start module, or a combo unit that offers security with remote start features.

Security: This means that the car alarm system is just that. No bells and whistles, just a car alarm system.

Remote Start: when installed, this allows the user to start a vehicle from a remote location. Remote start modules and security with remote start alarms often require an additional vehicle specific bypass module to complete installation.

Security with Remote Start: This means that the system incorporates both features listed above.

Security with Remote Start
Car Alarm
If "Yes", the system will have alarm security features to help prevent vehicle theft and tampering. Remote start modules without alarm features will have "No" for this value.
Remote Start
If the alarm or remote start module has "Yes" for this value then the system has an electronic device that allows you to start your vehicle by remote control without actually being inside the vehicle or using the key. The remote start system supplies the vehicle with power and simulates a start just as if you were inside using the key. Select vehicles require additional accessories or immobilizer/bypass modules to use the remote start feature.
Keyless Entry
Keyless entry allows you to remotely lock, unlock, and open the trunk of a vehicle if that is equipped with power door lock motors (actuators) and power truck motor (solenoid). Door lock controls via the remote are found on nearly all of today's car alarms.
2-way Paging
Alarms with 2-way paging inform the user via remote vibrating/audible/visual alert when the alarm is triggered. The pager must be within range to receive the transmitted signal.
Number of Remotes
The number of remotes included with the alarm system purchase.
Number of Buttons on Primary Remote
The amount of buttons on the Primary Remote generally equals the number of functions that you can use your remote for. Some remotes have auxiliary buttons which can perform more than one task per button.
Main Transmitter Type
LCD and OLED transmitters display various screen savers, warnings, alerts and other features on the face of the remote, rather than first generation button-only transmitters. They provide more information typically and other features.
Button(s)-only with LED Lights
LED/Display Color
The color of the LED indicator(s) on various items such as button-only car alarm transmitters, various chargers, cell phone accessories and other products.

For OLED or LCD car alarm remotes/transmitters the display color refers to the color(s) of the screen.
Number of Vehicles Supported
Some higher end car alarm systems can support multiple vehicles. This is the number of vehicles that the works with.
Number of Auxiliary Outputs
The number of auxilary outputs that the car alarm system supports. These outputs are left over from the total number of channels. They can be used to add on other options or additional features to a vehicle.
PC Programmable
Custom, advanced programming options through one or more of the following: PC, Pocket PC, PALM Pilot, Valet SW or Remote Transmitter allows for advanced controls of your alarm's functions.
Smartphone Compatibility
These are the types of smartphone systems that the car alarm system is compatible with.
Professional Installation Recommended
This will indicate whether or not we recommend going to a professional installer for this item. Some items have complex installations that should only be done be professional certified installers.
Built-in Bypass Module

Convenient Features

Panic Mode
Panic mode allow the user to be able to set off the alarm from the remote.
Trunk Release
The trunk release option allows for integration and control of the trunk latch. Additional parts may be required.
Valet Mode
Valet mode is a car alarm setting that adjusts system to less sensitive settings when allowing a valet to park your car and similar settings.

Alarm Features

Paging Range
The maximum distance that the car alarm system will work with the wireless remotes.
Not Specified by Manufacturer
Number of Car Alarm Channels
The total number of channels that the car alarm system supports. These channels can include locking and unlocking doors, opening the trunk, remote start, and many other options.
Most car alarms come with a siren that can be installed. The siren will sound when the car alarm is triggered the alarm goes off.
Shock Sensor
The shock sensor is designed to trigger an alarm on light or heavy impacts and vibrations (standard sensor included with most alarms).

A dual zone shock sensor is a feature of proximity and shock sensors only. Zone 1 ( light impact on shock sensor and short motions(adjustable) on proximity sensor) will trigger warn away chirp to warn intruder that car has an alarm without setting off the full alarm. Zone 2 (heavy impact on shock sensor and extended motions(adjustable) on proximity sensor) will trigger the alarm to “go off”.


Remote Start Features

Cold Start Timer
Great for those on a set schedule who need their vehicle to warm up at a specific time every morning for example.
Turbo Timer
Some remote start systems have turbo timer feature which allows the vehicle to run for a specified amount of time after exiting vehicle. In turbocharged vehicles this prevents hot oil in the engine from choking up in the lines. Hard driving can raise engine oil temperatures to dangerously high levels. Proper cool down is essential for a healthy turbo and engine.
Compatible with Diesel Engines
This means that the remote start system will work with diesel engines.
Engine Start Intervals
Some remote start systems offer feature to protect your engine. The engine start interval feature will start the car at particular time intervals or when the engine has reached a certain temperature. This feature prevents the engine block from freezing.

Great Product for a Great Price!!

December 19, 2012

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!

January 27, 2012

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 alarm for the price.

July 28, 2012

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.

because I see that its a good alarm system and I Don't need really expensive
Brian T on Feb 1, 2015
Will this system work for an 02 silverado duramax diesel?
Noah R on Nov 10, 2015
Best Answer: look at the manual page 22 says diesel
Connect this wire to the wire in the vehicle that sends the signal to turn on the
WAIT-TO-START bulb in the dashboard. In most diesels the wire is negative
(ground turns on the bulb) and the GRAY/BLACK wire can be directly connected
to the wire in the vehicle. If the vehicle uses a positive wire (12V to turn on the
bulb) a relay must be used to change the polarity.
Note: A 1-amp diode must be installed in line on the factory wire between the
wait-to-start indicator and the ECM. (See the following diagrams for details)
