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.

Viper SmartStart


Gives you complete control your vehicle's security and remote start system from your smartphone with the free downloadable SmartStart app. SmartStart eliminates the need of additional keychain remotes and as long as you in an area with cellphone reception, you don't have to worry about being in range of your vehicle.

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.

Keyless Entry 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
Sidekick Remote Transmitter Type
Some car alarms and remote start systems come with more than 1 transmitter, which is referred to as the "sidekick" transmitter. Most LCD/OLED systems come with a button-only sidekick transmitter, while select units come with an additional LCD/OLED transmitter.
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.
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
System Type
This refers to the type of remote start system, whether it is an add-on or a complete kit.
